thank you Dr. White!

It's still just impossible to really get one's head around just how long the timelines of the early earth are. Billions of years can pass almost as a footnote.

This is the best geology channel on YT. You can explain physics better than my uni course.

The best lectures ever ! I'm not into geology but it's insanely interesting with you !

Dr. White is one of the most competent geology professor I've seen. So clear and concise and full of facts.

This guy is an encyclopedia on two feet! British gentleman with lots of pure geology to offer. Thank you Professor White.

What I like in Dr. White lectures is the high density of useful informations. He covers just about everything geology has to offer. He is even more polite than me (I'm Canadian). Is he from Wales? Thank you for the upload.

Awesome Chris. Thank you so much for this presentation. I've been looking for this spatial description of historical plate tectonics. Excellent!!!

OMG I just found you and I've been listening to you all the time. I'm not a geology but biology student but the way you're explaining everything is amazing. ❤❤❤❤❤❤

For a different paradigm you may want to wach is Genesis History? And then Genesis After the Flood. Seems logical and legit.

Its interesting. You don't alow comments on some of your vids. Like the lecture 6 about geologic time.

Brilliant series Dr White. Bravo 👏👏👏

Did not a recent study show that the isotopes of oxygen of comets and the earth do not have a close match? Could the water we gained have not arrived inside the rock of impacting asteroids?

What about the Room Problem for granitic intrusions? Any solutions?

Thank you for the lecture. Can you please help me with sources you followed for making the lecture.

Im sharing this playlist everywhere - it is top teir info and very well done. I would love love love you to update this series with the latest research and go into even more detail, just so interesting - thanks you!

Oh yaaaaa you are back!!!!!

Excellent lecture series!

New research has shown that multicellular very small life appeared 1.2 billon years ago :) There are also indications that life probably got going around 4 to 4.3 billion years ago. You skipped over the Theia-earth mk 1 collision? Recent research proves that there indeed was a crust 4.4 billion years ago based on the Australian zircon inclusions as you mentioned, most amazing,plus the Acasta gneiss is 4.03 billion years old, and the Nuvvuagittuq greenstone belt in Quebec is 4.28 billion years old. Most definitely these oldest rocks are rare! Do you agree with some ideas that the 1st granite may have been formed from asteroid impact melts? Also, you 1st say that water would be rare to absent on Hadean earth, but then you say common volcanism would have released water vapour alongside other gasses. does that not imply more water was present earlier, esp in line with the Jack Hill zircon research? Do you agree with some research which suggests Archean earth was mostly basaltic crust with many volcanic islands and a few tiny mice continents?

These stimulate my imagination greatly, thank you doctor.

Where's part 2..?? i see part 1 which i've already watched.... & of course, this is pt3....but i cannot find pt2. help please oi hate doing things incomplete as specially when it comes to learning & knowledge i want to see & hear all parts ....

i love how hes so educational and precise yet relaxed and relatable so ANYONE weather you're in school or just wanting to learn something new, you'll follow along just fine.. at one point hes like "so here's north america, Gondwana is doing its thing" made me laugh and kept my attention from start to finish because he's just being himself and not too ....uptight (for lack of a better way to put it). great work and hope to see and watch more from you

Hey, I watched this recently: The Largest Mountains To Ever Exist Were Created By Prehistoric Life It basically states that all the mountains on Earth were caused by Microbes/Bacteria & plate tectonics. The theory being that all the dead matter from life under pressure turned into shale rock? Or some rock, I forget which. And that made a super slippery layer that meant mountains could form. And apparently, before life existed on Earth, there were no mountains. So my question would be, does this mean that any mountains on any other planetary body in the universe that also at some time in its history had a hot centre, and plate tectonics, does it mean that if that planet also has mountains, that it would prove 100% that that planet either has life on it or once had life on it in the past?

I wish nothing but the best for you. I have so enjoyed the content you have already generated. I found it so informative and interesting. Please bring us more when you are up to it.

Does anyone have the answers 🥹

Thank you for this nice presentation, very educational.

I've come up with an entirely different theory to explain the shape of the greenstone belts. What if they reflect something like dunes, but on the interior side of the crust? When the earth was young and hot, perhaps there were dune-like deposits on the inner side of the crust that were shifted as dunes by wind. Eventually, the interior side of the crust would have been levelled and the combs of the dune pushed upward, creating mountains, between which the sea flowed in, allowing for the shallow sea materials to form.

A priori, in Archean times, we can't exclude internal mantle forces that would have simply pushed the oceanic crust upward. Also, is it really impossible that the Greenstone belts were pushed upward by enormous amounts of underplating?

As I understand it, the continental accretion works because mainly shallow waters are being eliminated.

One extension of the back arc model one could come up with is that the compression event is weakened by competing downward magma streams on the left in the picture, allowing the process to repeat itself on the right part of the islands. In case of an equal split of the original island arc, we would then see though that the overall volume of the stripes decreases exponentially in one direction.

Wouldn't the presence of sandstones, limestones and banded iron formations suggest that the greenstone (which formed at a deep sea environment) was later lifted by plate tectonics to shallow sea environments, where the sandstone etc. deposits formed?

I also wonder what clouds would have looked like in the early earth's atmosphere (if they even existed). Would they have also been white, or rather tainted like on Venus? That may also have affected the amount of radiation absorbed by the clouds.

I wonder: About the Titanium experiment, were the zircons all dated differently, or are we simply given some confidence interval? If the former option is true, it may be interesting to look at whether zircons from 4.1 Ga or younger show more signs of low temperature melting, which would favour the theory of Late Heavy Bombardment water addition.

Excellence in boring, therefore good #bedtimelistening

Yo Mr. White! Yeah, science!
