It would be really cool if you could do a video on the formations around Maori Bay. So much interesting formations there with all the columnar jointing and lava pillows, and I'm sure Bruce could tell a tale about how those formations came to be there.

As an Aucklander I’m familiar with pretty much all the rocks formations you’ve looked at - when at Piha I spend more time looking at the rocks than I do the sea. Thanks for making sense of the geological jumble there. Although it’s obvious that much of the formations are volcanic in origin, I had no idea that there existed a volcano that has been eroded away by the sea. All things succumb to time. One question though re the Piha conglomerate. I had always thought ( novice factor 10!) that it was sedimentary, since all the smooth rocks were contained in another “sand” medium. But I’m wondering now if these are in fact smooth due to the erosion of the whole conglomerate i.e. if you were to dig one out of the conglomerate it would be rough?
@OutThereLearning2 жыл бұрын
Actually - although they are derived from volcanic activity, the conglomerates are sedimentary as they have been transported and deposited down the slopes of the volcano. The rounded cobbles were worn smooth by being moved and abraded during transport. The more angular fragments have been rolled around much less. If you were to dig into the conglomerate the rocks you pull out would be similar to what you see on the surface. Great question - thanks for asking.

Same as userps1 - I'm an Aucklander, live in Mairangi Bay on the north shore. Visited West Coast beaches regularly. Only recently learned about the massive undersea volcano out at sea. Imagine if we could see how it was, where it was, and how it's totally eroded and invisible today. Just as well, or the stunning Gannets at Muriwai and other colonies would have suffered terribly from any volcanic activity. Well, i suppose the volcano predated the emergence of trans-Tasman gannets, but i could be wrong. Don't know much about Gannet species or evolution. But their ancestors would have seen the volcano slowly dying out and being eroded. Deep time !!

The Taniwha sent huge rogue waves; strong "pull you into the sea by your ankles" backflow; and other random things up towards the beach. They were right. Further, do we know if there is any residual volanic activity deep down in the core?

Yes both are the eroded sides of stratovolcanoes of a similar age. The main difference is that at Piha the volcanic conglomerates were deposited under the sea on the largely submarine slopes of the Waitakere Volcano. At Whangaroa the volcanic conglomerates were deposited on land as part of the laharic ring plain, rather like the gentle ring plain that surrounds Mt Taranaki today or the Desert Rd area which is the ring plain of Mt Tongariro and Ruapehu.

That was interesting, enlightening, and ... _exciting._ I wondered about the wisdom of walking into/through those tunnels, but I guess that Bruce Hayward is living proof that, at least for the past 45 years or so, that has been safe to do. I also wondered how the rocks that were of "different compositions" (at the 9:00 minute mark), could all come from the same volcano. I assume they were created at different times. Most of the hardened lava looked like basalt, but there was also mention of some andesite. Was the stratovolcano that produced these rocks over a rift system? Was it created by an oceanic plate subducting under what was once land but now is undersea? Perhaps it's obvious from these questions, I'm a recent student of geology. It's all pretty thrilling, actually! Thanks for a great tour.

Why is Taitomo island south east face so smooth in a circular type of shape, it is not a flat face at all, it is round - when all around it are rough scalloped out caves on other cliffs. Also, why is there a flat face facing north exactly on top of Taitomo Island above the fallen rocks 12:54. You can see the flat face at 19 seconds at the summit of Taitomo island not only is it facing north exactly but it is also perfectly perpendicular, and is a flat face - perfectly. Seems odd given it is created from lots of little stones held together in a matrix that it should fracture flat and perpendicular does it not...?

So why has the volcano out to sea eroded to the point that it's beneath the waves when the portion that makes up the Waitakeres hasn't?
@BruceHayward12 жыл бұрын
The Tasman Sea actually had eroded all of the volcano down to sea level by about 5 million years ago during a period of little tectonism. Then in the last 5 million years we have had another phase of tectonic activity that has progressively pushed up the Waitakere Ranges, more so in the east than the west so that it is tilted down towards the NW. If you look at the Waitakeres from a distance you can see their flat gently tilted top, which is the 5 million year old sea floor that has been pushed up. The flat top is actually just the ridge crests - in 5 myrs this uplifted surface has been deeply eroded into valleys by streams and the sea is once again carving away the west side forming the cliffs as it eats into the uplifted rocks.

Would have been nice to mention why the tunnels follow the intrusive dikes of lava, it is because that lava, although considerably harder than the surrounding conglomerates, cools into a basically hexagonally jointed pattern which is very easy to erode in blocks. The Taitomo tunnel, blowhole, and the other tunnels shown all at least initially follow the line of these basaltic intrusions. There are some fascinating ones at Bethells Beach (Te Henga) as well, mostly at the Northern end, including a connected series running beneath one of the small peninsulas there. Just FWIW.

The river rocks, the cliffs are full of them up and down the coast, must have been a huge river to deposit so much river rock sediment above todays sea level which then have deposits of rock atop. Everywhere the camera points it seems river rock is exposed, not being shaped by wave action, rounding, but being exposed as it is, imbedded and pre river rock rounded without a river. Maybe it’s a Magic underground river, I saw one once.

Excellent video thanks; your time and effort is appreciated! I was at the south end of Piha beach today looking at that vertical section of conglomerate that had water running down it wondering why it was less eroded than the surrounding dry conglomerate. You have answered my question! My guess as to how the keyhole tunnel formed on Taitomo island was that there looked like there was a dyke (igneous intrusion) there but most of it had been eroded away. I would have expected the surrounding conglomerate to erode faster. Would this be because the border between the dyke and conglomerate served as an exposed crack for water/wave action to penetrate and then the dyke, being formed on a vertical plane, was more prone to sliding downwards with gravity?
@OutThereLearning2 жыл бұрын
Your observations and thoughts about the eroded dyke are very astute. The dyke is much harder material as you point out, but is broken up into pieces along the cooling joints. This would have allowed loosened pieces to drop out under gravity. We did in fact have this in the original video but left it out for the sake of length / time. Great that you spotted it!

I don't know- those volcanic conglomerates look composed of awfully water-rounded cobbles and boulders to me. And then deposited in very water sedimented strata. All this appears to be fairly level strata deposited by a fast moving debris flow thousands of feet thick and miles long. This is identical to thick stratified gravel deposits found in many places on earth that are in some places claimed to be from glaciers but in others from debris flows. Given that the debris flow theory has eye witnesses to modern examples with no one disputing it, I go with the obvious.
