Could you teach us how to use 365nm uv light to aid the identification of igneous rocks? Or maybe it is not possible at all?

Very good course. Mud is converted to shale rock by pressure solution of, most prominently, quartz. Google "Proposed Model for Shale Compaction Kinetics " .

Close to the end of 2024 college student in an intro geology course! This video is so helpful!!! You rock!😜

Hello sir

Thank you! My gifted middle school students will definitely benefit from this. Also a great refresher for me

Hi

Lesson ONE for geologists should be the explanation of the catastrophism theory. This theory is based on the findings of the French naturalist and paleontologist Georges Cuvier around the year 1800. During the excavations when making roads through France, he discovered the fossils from land and sea creatures in the same layer, strata. But also in the layer on top of that and the one below. So he concluded that the planet Earth is suffering from a recurring natural disaster where flooding must cover a large part of the land even on high places. But I assume that this theory is neglected because nobody could think of the possible cause of regular floods. Ancient books tell us that our planet Earth is suffering from a cycle of seven natural disasters. The only possible cause of such a cycle can be a celestial body that orbits our sun in an eccentric orbit. Than that body, planet, will be close to the sun for a short while and disappear in the universe for a long time. That celestial body is also mentioned and even depicted in many ways. The Aztec Sun stone is a warning for this event. Abundant and convincing evidence about this cycle of natural disasters and its timeline and many images are available in the eBook: "Planet 9 = Nibiru". Search: nibiru = 9

Thanks a billion ❤❤

This is very helpful! More identification videos please 😅

Hi with rhyoliite it has an aphanitic texture rather

Great explanation, thank you!

It's 2024 and I'm still being help by this 3yr old video. Thanks

I studied geology in college in 69-72 and the understanding on this was not as well-developed yet. This is the best explanation of magma differentiation and melting curves I've seen since then. This pulls it all together. Well done.

I like this video but the earth isn’t billions of years old, but a few thousand.

Great practical experiments that can be repeated by anyone in the backyard. The essence of science. Perfect. Thanks for putting this together and posting

Cool experiment with the different melting temperatures

Yes thank you so much

I agree.

Wow.

I’ve Been looking for a. Experiment that shows a chemical to cool (both slowly and quickly) into a solid to show how different size crystals form. I liked your experiment with phenol salicylate. Not sure where I can find some. I’ve been experimenting with making candy with hot sugar, and cooling it in the air for a control and in the oven at its lowest temperature for the experimental conditions. Unfortunately haven’t had much luck with it. Just want to have something that’s accessible to everybody at home

Thanks for this video, very helpful for our earth science class!

I like u man

Very helpful video. Thank you..Sir...

finally not an indian

Thank goodness for YT time machine! Great vid!

hi sir i am mining engineering student and i am looking for the best geology expert for my research pepr can you help me.

geology for 5 year olds

Glad to see more content from you 😊

Jesus was there for me when no 1 was. Every time I sought solitude in my 4 placements. I felt His peace and love. He's kept me alive when most people made me not want to be. Please, you never know when your last day will be. Choose Him. You are His favorite. ua-cam.com/video/mt-UwafwXYk/v-deo.html

Thank you :) learned a lot here

Can I have your contact details plz..I have some meteorite that need to be examined.they mostly contain crystals. And I witnessed this meteorite crash.however another scientist that I consulted just by looking at is saying terrestrial rocks.

Thank you for sharing this

You start off with the grid with 4 Composition categories and the two textures and then jump to the two categories of intrusive and extrusive and never get back to Phaneritic and Aphonretic. you present some good information, but this misdirection was a source of confusion.

Fantastic! This is really helping with my study :) You explained the current section I'm working on so well.

Really helpful to supplement my uni module :)

Please make another video on magma evolution along Namibia region.

Please make another video on magma evolution along Namibia region.

You explained so nicely 👍

Thank you sir

Thnks sir for the information regarding igneous rock.

Sir any new videos on this topic?

Hi

Thank you so much your videos are really helpful !

Thanks you sir 😊

why are you made only a few videos we become so interested with geology
