Identifying Metamorphic Rocks -- Earth Rocks!

[@kattiannavaughn6942]

The pile of pens... Awesome way to show how foliation occurs. Thank you

[@nickolaykolev8986]

Helps a lot in school. My son told me that he got %100 on his test because of this video.

[@EarthRocks]

Yay! So happy to hear that. Thanks. :)

[@sherali9383]

Great

[@jjcvmd]

The illustration of foliation using pens and pencils is so simple yet the most brilliant metaphor I’ve ever seen

[@chrisavila8693]

Seriously you need credit

[@Wishball38]

This is the best video on metamorphism I have seen. I have extensive chemistry background, so it may be that the way things are explained here makes sense because I think of the world in terms of atoms and their movement and rearrangement. I think this is the most fascinating and helpful video on explaining mineral formation and and metamorphism at an atomic level that I have found, and I've watched upwards of 30 or 40 videos just on this topic. Thank you SO MUCH!

[@EarthRocks]

What a fabulous comment. Thanks for sharing your experience! It means a lot. :)

[@botryoidalbishhh3150]

The best information on KZbin to date. Thanks

[@koikogo]

Great info. Professional lecturer. Nice voice. Logical explanation. Easy to remember.

[@skylark1848]

I've always wanted to be able to tell /feel where a rock was formed.. this information you have presented is gold ❤️

[@nunyabiznes4471]

This was excellent! I was confused on how rocks change and the explanation on pressure and temperature really helped me understand the process.

[@WiekingderViking]

You do a very nice job. Showing the “stuff of geology” helps me to relate to the historical geology! Great graphics, great voice. Very picky professor Bob

[@carlamaeterrado8777]

I'm a geology student and your videos helps me a LOT!! Thank you :))

[@EarthRocks]

You're welcome. Thanks for letting me know. :)

[@IrishAndy001]

Great video with a lot of knowledge I love learning about different rock types how they were formed how heat and pressure can change them and learn all about geology.

I'll probably watch this 10 more times just to gain an intimate understanding ha

[@missemma8504]

I've watched it for more than___, I don't know how many times.. i always come here to watch this anytime before an interview or an exam.. As I'm a senior Geological Engineer Graduate. DONE my Undergard Degree 6 years ago.

[@bobketteringham4779]

Me too

[@aoconnor2933]

@@missemma8504 that's awesome. What do you do with it now? I'm barely only about to earn my Associates in LA with a focus in Math and Science before transferring to an undergraduate program in geology.

[@georgemcconnell5405]

Me too lol!

[@georgemcconnell5405]

Check out earth science x. It's a complete geology lecture and it's on the same level as this. I think there are 26 videos, going through minerals, igneous, sedimentary, metamorphic, plate tectonics, ground water, soils, volcanoes, mass wasting etc. It's a great KZbin course if you like geology.

[@bhavatharani7412]

Excellent video about metamorphic rocks.... keep make more.....

I've always enjoyed feeling different rocks as a child. ❤️

[@raieyahya8350]

it really help me a lot in our activity in geology, thanks for this video

[@spectator59]

I've recently taken up geology as a hobby, and enjoyed the video, but wow! so much new vocabulary. It's going to be a challenge to internalize it all.

[@supritisingha7909]

You are right

[@oscarmedina1303]

Same issue. I focus on on understanding and learning one new word per day. Really helps to have a sample in hand to examine closely.

[@ing-acnl9455]

these rocks are soooo prettyyyy i adore them

[@brento2890]

Excellent video !!!!

[@सीताराम-च4न]

Very informative video.👍 I have a question please. How are there alternate layers in metamorphic rocks? How is there a black, then light, then black band in Gneiss for example? Is this like nature is also conscious about color combinations.😁 How do they arrange like this?

[@EarthRocks]

Density -- the darker minerals are denser than the lighter ones. When the crystals are given some energy through heat, they can move around a bit and will separate in bands by density. We see the same thing with sand grains settling on a hillside.

[@stephenrocks7004]

I have spent most of my adult life scouring our local deserts in the great Southwest San Diego and Mexicali and Calexico. There are areas that are restricted to all people along the old Butterfield stage Road. I have ventured into these areas with great caution and there are no signs of indigenous habitation. Back in the 1400s it was reported that this area was inundated by the sea of Cortez. I have found many large Jipson crystals and igneous rocks associated with volcanic activity yet the one element that confounds me are the manganese nodules in small piles strewn about. I sent several samples to be analyzed and they came back as 98% pure manganese the rest being iron. So my question is, how does manganese nodules form in ancient oceans and seas?

[@EarthRocks]

Manganese nodules form on the bottom of the seafloor as waters are supersaturated with dissolved Manganese. It may be you're finding some deposits left behind as old seafloor rocks have eroded/weathered. Manganese oxides also form as part of the chemical weathering process when minerals dissolve (especially in the desert), but that just creates a stain on the surface (desert varnish). I bet on the old seafloor deposits. You can see them described in part of my Ocean Sediments video: kzbin.info/www/bejne/eYDdZYufptKEZ7s

[@stephenrocks7004]

@@EarthRocks my surname is Rocks, and my Christian name is Stephen. So as much as I enjoy Rock hunting, my college degree was in chemistry. I hear now that industry is looking for manganese deposits in the search for rare earth metals. The samples I turned in for analysis showed two elements, manganese at 99% and iron at one. So why are they looking for manganese when there is one percent left over as iron and possibly a fraction. And of that could be rare earth. So what am I missing in this equation? as a neophyte ?

[@surajpatel3044]

I thought converging continent and subduction zone are same. What's the geological difference. I am not asking the difference of pressure and temperature gradient

[@EarthRocks]

Continents don't subduct. So when two continents collide, they create massive mountains with deep roots, but no subduction. Only when one of the converging plates has ocean crust at the boundary will there be subduction. I have a video on plate tectonics basics that can help you: kzbin.info/www/bejne/aKbLaYpqq6x_h5I

[@surajpatel3044]

@@EarthRocks our teachers said indian plate is subducted into Eurasian plate and himalayan range is formed. Is that wrong? Please clarify. And thanks a lot for the previous reply. I owe you ma'am.

[@EarthRocks]

@@surajpatel3044 Yes, subduction brought two continents together. The subducting Indian plate had continental crust attached to the ocean crust, and once the portion of the plate with the ocean crust had completely subducted, the continental portion collided with Eurasian plate and formed the Himalayas. So subduction brought the two together. See the Plate Tectonics Global Impacts video: kzbin.info/www/bejne/j2bEfqGIfLujlZo (look at 7:14 onward). And you're welcome. :)

Minerals aren't like pens. Sand would be better for illustration. Awesome video. As Shawn Willsey calls them a general term, sexy rocks 😂

[@EarthRocks]

Thank you for your feedback. 😀 Note: unfortunately sand wouldn’t show foliation. It’s equidimensional. To see foliation, you need an elongated mineral like actually actinolite or kyanite or hornblende. These have shapes similar to pens. Or flat planes like micas (and paper). Only these will align when put under pressure.

[@noahraby53]

LUOA gang!

[@TheMrdoc26]

Wholly Mountain Building Batgirl!!!

[@thebestofallworlds187]

so if a rock has foliation, it's always a metamorphic rock?

[@EarthRocks]

Not necessarily, but usually. Sedimentary rocks can have layering, and as pressure is added, that layering can turn to foliation (the clay minerals in the sediment align). So some sedimentary rocks that are grading into metamorphic through addition of small amounts of pressure can be foliated. But that's a gray area (the zone when sedimentary turns into metamorphic).

[@thebestofallworlds187]

thank you!
