The Geologic Oddity in New Zealand; The Banks Peninsula

[@Fiftytimes]

I live in Lyttelton! My house is perched right up high on the side of the crater overlooking the Port. Thanks for such a great reminder of my local geology and for such a fascinating channel 🌋

[@complimentary_voucher]

My family used to have baches in Little Akaloa but now we reside in the *superior* volcano vent in Port Chalmers.

[@GeologyHub]

Sounds like a fun place to live :). By chance do you know what rock types (volcanic of course) are exposed under/near your house?

[@adriennefloreen]

I just looked at pictures of that city on a google search because it looks amazing, with the city in and going up the sides of the steep crater. You should make KZbin videos about life in your town, and the rocks and plants that grow there too, because rare plants grow in volcanic rocks.

You should go to rapaki bay and take a spade, find the spot on the sand (where the waves are breaking) where is warm water and dig a hole, a natural thermal spring in the hill means you'll have a nice warm pool to warm up in after a dip!

[@davidk6264]

I lived in Christchurch for a decade. It is totally flat, and even though you can see the hills of the bank's peninsula, it still felt bizarre seeing Littleton after such a sort of journey through the tunnel. You arrive in a completely different land.

[@stryka777]

Lived here my whole life, hiked it, surfed it, swam it, admittedly haven’t done any diving, but I still feel like I could spend a whole lifetime exploring nooks and crannies and then need an additional lifetime to see the rest and then some. Blessed to grow up here.

[@PiefacePete46]

There are other countries with interesting features, but New Zealand really is the concentrated package. You can see more variety in one day than you can in many places where you must travel vast distances between interesting scenes. You have obviously spent time exploring the country... too many New Zealanders take it for granted. They don't know what they are missing out on! 😊

too many fault lines and each fault line, I was told is pressure building up and blowing up over due... The entire new zealand is geo wonder hope it stays that way without blowing up..

[@wordzmyth]

The Heaphy track passes through 4 different landscapes in a 4 day walk. I am from the North islamd and it blows my mind how beautiful the south island is. The track follows a road that was never built from the top left of the south island to Karamea on the west coast. It will stay with you forever.

[@riverAmazonNZ]

I live near here. The landscape is so beautiful, with evidence of volcanism and ancient sea erosion (cliffs!) before the plains built up. The plains are almost entirely gravel. Fun fact: the Waimakariri river used to run south of the peninsula, through where Waihora/Lake Ellesmere is now. Most of Christchurch is sitting on the Waimak's shingle fan.

[@SpaceLover-he9fj]

Wow..

[@DaRoachDoggJR.]

Mostly gravel? Which plains? The canterbury plains? No, otherwise it wouldn't be an agricultural hotspot. I assume you mean down toward lake ellesmere, where the ground is more gravel, but still nowhere near "almost entirely gravel"

[@riverAmazonNZ]

@@DaRoachDoggJR. Fundamentally, not at the surface. As Wikipedia says, “The Canterbury Plains were formed from Quaternary moraine gravels transported from the Southern Alps and deposited here during glacial periods in the late Pleistocene approximately 3 million to 10,000 years ago.”

[@jeffbrooks8024]

I visited Christchurch in 2012 in the aftermath of the 2011 (I think) earthquake and I was certain I heard geologists say that the area is underlain by fine grained silts and sands, the shaking of which caused liquefaction. Evidence of this can be seen on the beaches where the black mineral sands were brought to the surface and overturned the yellow beach sand

[@wordzmyth]

I didn't know that but do remember the words alluvial floodplain. Under 2 of the houses I knew we underground streams. There are springs all over it and it should have been left for agriculture. As we see now it was a disastrous place to put a city. But we can't afford to shift it and flat land by the ocean is so attractive. Pity about sea level rise. So many NZ cities will be affected and soon. We just had a report showing which areas of the coastline are being affected first. It's already starting to happen. My local beach in Orewa north island has high tides up to road level and huge banks cut into the beach sand in storms.

[@_Opal_Miner_]

Thanks for this vid. The geology of Banks Peninsula is amazing. It's just a marvellous place to go walking and there are numerous campgrounds in the bays. We are very lucky that you can go from the centre of town to the top of the hills in just 15 mins with views right over the ocean and to the alps. The vast majority of the sediment that has built up the Canterbury plains (between Banks Peninsula and the Southern Alps) is made up of a slightly metamorphosed rock commonly known as Geywacke (it's a biotitic quartz arenite that was originally sediment eroded off the Great Dividing Range in what is now Queensland.. Bury it, heat it..... voila) deposited by the 3 main rivers whose source is in the alps. They migrate across the plains very slowly but also undergo rapid avulsion and find a new course each time the massive strike/slip Alpine Fault ruptures. We end up with interbedded layers of course gravels and cobbles with overbank fines from flood events. Lake Ellesmere, seen at 01:30 , never gets much above your head and used to extend about 2/3 the way around Banks Peninsula. While testing I find lacustrine sediments covered over with alluvial silts right up to the boundary of the city. Then those deposits swap to marine deposited sands for the rest of the way around the peninsula. In fact it is one of the more complicated sedimentary deposit areas I have dealt with. In a 20m bgl test I can find alluvial silts, peat from marshes and riparian vegetation, marine sands, small tsunami deposits, aelion loess, colluvial and landslip jumbled messes, large clast river deposits from fault rupture or glacial dam breaks. Never a dull day trying to figure that cat's breakfast out. That the volcanic complex was twice as high and an island is a great way for me to teach my kids about the changes that can take place over geologic timescales. You could easily fill 50 videos with New Zealand geology. Sorry for rambling. Geology....you get it. Thanks again.

[@OpaSpielt]

I know this part of the world only from maps and the wonderful street view, when I was checking the influence of the strong earthquakes of Christchurch on the city by the history of pictures. Of course I went virtually also in that peninsula. The contrast of this very mountainous peninsula and the flat parts in the northwest is impressive. While I was able to explain the flat areas with erosion from the New Zealand Alps, the peninsula was still a mystery for me. Thanks for this video, it explains my unasked questions. The two bays, I think, are wonderful natural harbours in case of rough weather conditions, which I guess are quite common in that part of New Zealand. Have a nice day 🖐👴

[@k.c1126]

Same. I remember how concerned people were about the potential devastation on the peninsula at the time ...

[@stephenprice8172]

Great video, and great comments. Captain Cook ( english explorer ) named it Banks Island after the botanist onboard his ship. If he had gone ashore and climbed up to the rim of the volcanic crater he would have seen the entire Canterbury Plains with the Southern Alps that stretch the length of the South Island in the distance. The English settlement of Christchurch ( there is one in England as well ) was built on a swampland left after they redirected the Waimakariri River to flow north of ChCh ( short for Christchurch ) and when they tried digging a canal from the estuary of the Avon and Heathcote Rivers ( more like drains than rivers now ) they discovered very quickly that the seawater was starting to flow downhill towards the center of Ch Ch !!! So they gave up that idea of using english barges towed by horses to move everything from a wharf at Redcliffs. I was raised in ChCh and have spent many, many hours exploring the entire area. If you are visiting ChCh, put aside plenty of time because there is so much to do in this area. I have a yacht moored in Lyttelton and it is a great area to do some sailing. If you can, stop at one of the many airB&B's on the northern side above ChCh ( Sumner to Cashmere suburbs ) and enjoy the night lights of ChCh and the views. Taylor's Mistake is the best surf beach, and do a paragliding tandem flight off the Summit Rd above it. You are permitted to walk all over the DOC administered land on the entire Peninsula, and there are camping grounds in almost all of the bays.

[@chubbyballsack]

great comment! chch was an incredible example of peak anglo saxon civilization planning & civil engineering brilliance - they had to drain the swamp and tunnel through a volcano to pull it off - technology that hadn't even been perfected - the only deep water port, lyttleton, was only accessible by a barge for the first 40 odd years ( out of the harbour & around the south side of the peninsular to ferrymead, the mouth of the heathcote river) until a rail tunnel was bored under the volcano - the first time ever done - and pulled off without a hitch with digs from eather sides meeting in the middle!

[@stephenprice8172]

@@chubbyballsack The rail and a road tunnel both go through at Ferrymead Valley Township, and the old "Bridle Path" track that the early settlers from England walked up from Lyttelton, and down the northern side to Lyttelton is a great walk to do. ( catch a bus back to Ferrymead Gondola Carpark in Ferrymead beside the 'Bridle Path' ) The Summit Road is a fantastic road to get really great views all around the Plains, the Christchurch City, and the New Brighton Beach and the Ocean. Then there is the Ferrymead Historic Park, a minitown with all manner of historic buildings and other working exhibits. Passenger trains use to run between Lyttelton and Christchurch with many stops along the way, but the Government sold the NZ Railways off and it was carved up and sold off for scrap mostly. The land assets were what the Corporates wanted, and around 15,000 people lost their jobs. If they had kept the trains running then there would now be a very quick and cheap electric train fast rail system from the Port into Christchurch central, but no. Even the big Christchurch Central Railway Station was demolished, and all the sheds and the huge shunting yards areas are now car sales and factories. So much for progress, massive truck and trailer rigs block the roads and cause massive pollution, and all the cars that people are forced to use because the rail system in Christchurch/South Island were scrapped. You can catch the tourist train to the West Coast, but it is actually cheaper to fly there. Christchurch to Springfield is 1hr 20 mins by car, and $120 one way by tourist train. The real gem of the entire Banks Peninsula is the french village of Akaroa. Well worth a few days rest.

Akaroa has some really interesting history behind it too, in 1838 the French Captain Langlois set out and began a colony in Akaroa. After the signing of the treaty of Waitangi in 1840, the French colonists there essentially gave up on trying to create an independent colony, and assimilated into the other British settlers there. You can see the French influence there today, with place names such as Duvauchelle, and French-inspired buildings (one such example is the Langlois-Éteveneaux House, which is the only surviving house erected by the French settlers).

[@malectric]

Thanks for this. This is the first time I've seen an significant detail on the volcanic past of this area of the country where I live. I knew Banks Peninsula and Dunedin harbour were old shield volcanoes but knew little about the eruptive history.

[@SpaceLover-he9fj]

The Banks peninsula looks so weird! It has alot of volcanic cones, but thanks to erosion, it looks ragged, unassuming and rough, I like it! Zealandia, as mentioned by different comments, is a geologic oddity itself. It is one of several microcontinents, which are landmasses smaller than the usual 7. Another microcontinent is the Kergulen (may have misspelt that) plateau in the southern indian ocean, where the Kergulen islands are located. Tectonic rifting can be an immensely complex process. Other than a rift dividing plates from each other, the rift may suddenly change course, fork into two, go one path before starting another path and connecting the two paths, etc. etc. The complex process of rifting can be observed in the Atlantic Ocean, where the Mid-Ocean ridge forked from the usual route to between Greenland and Canada On top of that, northwest of Great Britain, there’s another complex situation where the Mid-Atlantic ridge jumped several times, producing a piece of continental crust that was left put in the middle of the ocean. Interestingly, Zealandia’s western part fits with Australia’s eastern part. It is also interesting how much land erosion, uplift and volcanism (even explosive volcanism) can add. When Mount Vesuvius erupted, the bay was extended by a lot. Herculaneum, once at the coast of the bay, is now no longer near it- It is much further away. When Mount Tambora erupted in 1815, its summit collapsed but its puroclastic flows and surges seemed to have extended the volcano’s land area. On top of that, shifting volcanic vents also occur on many other volcanoes, like monogenetic volcanic fields, complex volcanoes like Etna, Fuji, Mount Baker, Kilimanjaro, Emi Koussi, Ararat, some supervolcanoes and caldera systems and complexes like Toba, Yellowstone, Taupo, La Garita, Valles caldera and Long Valley caldera, maybe Aira caldera and Aso caldera can be considered as well, La Pacana, etc.etc. Do note that when I was referring to the shifting vents of supervolcanoes, I was referring to their other eruption types other than supereruptions. Supervolcanoes don’t always erupt in supereruptions. They can extrude lava flows, lava domes and produce phreatic eruptions, phreatomagmatic eruptions, deform the land, producing uplift and subsidence, etc. etc. There’s no need to be very terrified of a supervolcanic eruption, because it is unlikely it will happen soon. To those fearmongers, stop it. do research and supervolcanoes aren’t always super-violent, nor do they always erupt in a supereruption. Yellowstone has produced more eruptions in the last 2.5 million years other than the 3 large, cladera forming megaeruptions and supereruptions. That being said, are there any other types of volcanism other than the usual (Subduction volcanoes, hotspots, lithospheric drip, etc.) ones?

@geologyhub there are more volcanoes in Otago, which is the region below the Canterbury where Banks peninsula is.

[@BohumirZamecnik]

Thank you for the video! My brother lived near Akaroa for several years.

[@jo2lovid]

There are numerous roads along the summit tops of the caldera. As a result there are also lots of suitable launch sites for hang gliding, parasails, RC slope soaring, and dynamic soaring. It's such a great location for aviating sports!

Christchurch Resident Banks Peninsula will always be special to me, as the port hills to the south of the city dividing Lyttleton and Christchurch are practically visible from all over the city and into the Canterbury Plains. Driving in the port hills is a wonderful experience as the views of entire bays come and go all afternoon. I have a very fond memory of reaching the tip of one peninsula and seeing the pacific ocean with my dad. Beautiful place

[@dmays67]

The one place in recent years where I almost shat my pants driving a single lane road from one inlet to another on the peninsular. No barriers, no fences, just shear drops. An amazing place to visit ll the same as someone who has lived in many parts of NZ including Christchurch.

[@musicisajourney]

I was curious about this place as there are no other local volcanoes. Thanks for the explanation in cool video!

[@Lara-234]

Ahhh thank you for this, I'm originally from Christchurch, right next to banks peninsula

[@crisf7125]

Question: so did these 2 volcanoes help build New Zealand? Fascinating...

[@_Opal_Miner_]

Mostly what built the South Island of NZ was to subducting plates. One subducting West at the North and one subducting East down South creating a massive strike/slip fault that has pushed the Southern Alps up. These alps continue to get pushed up and the land that makes up the South Island is the erosion sediment layed down by rivers coming off the alps. The North Island is mostly built up by still active volcanism.

[@kaymish6178]

That was super interesting. I didn't know Te Waiponamu had any volcanoes; I thought it was all just land mass, and Te Ika A Maui had all the volcanisim.

[@bazza945]

Even Rakiura (Stewart Island) has one, Mount Anglem.

[@chrisbrown1462]

Soon as I saw the Google Maps image I thought, that looks just like the Sutter Buttes. The Buttes are in my backyard and are quite the sight.

[@SageRosemaryTime]

Valuable and enjoyable information. THANK YOU.

[@DrLeavingsoon]

We live right in the middle of BP between Little River and Port Levy Saddle. Loads of volcanic rock, baked red ash and clay. Can confirm this youtuber has it right. A rare thing. Nice job!

[@RahulReddy-eq5zy]

You must be stalking me mate since I was literally just in Akaroa and the Banks Peninsula a few days ago, by the time you uploaded this video I believe I was walking around the waterfront at Akaroa!

[@k.c1126]

I first paid attention to the Banks peninsula after the Christchurch earthquake some years ago. The geologic story of this volcanic complex is definitely an interesting one.

[@robinsonfriday]

Banks Peninsula is my favorite place on earth.. Worked on a farm near Le Bons Bay, for a couple of years in the 90. , went back to NZ, 3 years ago, and 1. stop was BP. Spend New Years eve in a forrest near Little River, and the sound of first the insects and then bird song around dawn, was breathtaking.. So was the drive from Hill Top to Le Bons Bay, via "the tourist route", but that was also nerv wrecking, pretty steep road and sharp bends, and all the Kiwis did it with 80 K/H. beautyful place.Going back some day, but right now the plane fare is tripled, so i wait..

[@griner65]

Love this area. Camped on a beach on one of those small bays. Also almost died by driving off the narrow road... I was singing spice girls and did not see the super sharp turn. Slowed down JUST in time

[@ytmndman]

Can you make a video on the Sleeping Giant formation in New Haven CT?

[@yzettasmith4194]

I'd love to go to NZ. Such a fascinating landscape.

[@ZoltanVaci0]

Great video! While you're investigating volcanic oddities, you should do a video on the Cameroon Line.

[@emmanuelg.3999]

Interesting video, every time I saw maps of the South Island it seemed interesting to me how it stands out in that sedimentation area

[@wilsonov87]

I had always wondered why there had been this seemingly random volcanism along the south island's east coast. Now I know, thank you.

[@hamishd6389]

And best of all, they make for some killer cycling and trail running. I'd go insane without these hills nearby❤️

[@rayopeongo]

I did a New Zealand cruise pre-COVID. The ship sailed into and anchored at Akaroa overnight, and when I woke up in the morning and checked the map, I was like WTF!?!?! It was pretty obvious that we were anchored in an old volcano. We didn’t have any plans that day, so I mostly sat pool side and researched volcanic activity in New Zealand. It was very enlightening.

[@gdr55]

Interesting. Thank you. I lived in Christchurch until 2012 and used to walk up the Bridal Path to look over into Lyttelton now I live less than an Hour from the Buttes in NorCal mentioned in this video.

[@brucekeach4882]

Can you do one on central Otago pleases and the geological anomaly on Galloway Station at the foot of the Crawford Hills?

[@nateroseman]

I live further north in the Wairarapa and I am wondering if you could look at the region as a whole, maybe focussing on the impact of the many faultlines and how they have shaped the landscape today. Great vid too.

[@gaijininja]

If visiting the area, take the Black Cat Tours swim with the endangered Hectors Dolphins in Akaroa harbour, and walk up to the Giant’s House on Rue Balguerie. Any of the restaurants and cafes are worth the visit too. Lovely locals, beautiful views, bloody freezing water. Black Cat supply thermals and very thick wet suits, but boys, your voice will still go up an octave when you jump in the water.

[@marinedrive5484]

It's a great commute from Diamond Harbour to Christchurch; over hill and down dale as you wind your way around all the little bays.

[@bethanymillar6991]

Oh my gosh eeee this is cool, i live in Christchurch :)) Great video

[@luannvondracek439]

Sent this to a friend that lives in NZ for his edification. What a fascinating planet we live on.

[@gonk123]

I'm studying in Christchurch, didn't even know this! Always wondered why the peninsula looked so out of place
