Just wondering if there are any areas around the world that have always been above water since that bit of continental crust formed. Never under a shape or inland sea, delta, etc. Presumably this would exclude any areas with sedimentary rocks in the stratigraphy?
I have a limited knowledge of geology. It's one of the fields I would like to know more about. Are the Appalachian Mountains one of the oldest on the world? I thought I heard that they may be.
And yes I actually wanna know what the rocks taste like
This will be the first of many educational videos. I’m trying to keep them as simple as possible. So, of course some more nuanced concepts behind metasomatism and the formation of nephrite are left out.
Please let me know what you think, share it with folks if you’d like.
I've only had one lesson on these plots and I already know these things are gonna be the bane of my existence by the end of my course lol
I am trying to get my hands on some Trinitite but I don't know which ones are authentic. It would be extremely helpful if you could suggest some sites where I can get authentic Trinitite possibly with an authenticity certificate. Thanks! :-)
Does anybody see the metamorphic layering bend toward the dyke on the side closest to the viewer? That would suggest left lateral movement (not implying that this is a fault) doing dike emplacement. Maybe I am seeing things but if you look at the opposite side near the sunglasses it seems like the beds are becoming parallel with the dike margin. That would be consistent with the movement I described above but once again I may be totally seeing things that aren't there. By the way this is in coastal Maine Paleozoic rocks.
Actually just off the the Monument. 4WD needed.
"Yohey Suzuki, the lead researcher and an associate professor at the University of Tokyo’s Graduate School of Science, explained, “We didn’t know if 2-billion-year-old rocks were habitable. Until now, the oldest geological layer in which living microorganisms had been found was a 100-million-year-old deposit beneath the ocean floor, so this is a very exciting discovery. By studying the DNA and genomes of microbes like these, we may be able to understand the evolution of very early life on Earth.”
WOW! I'm not geologist but my god the history on display there was BREATHTAKING! Has anyone else been?
I have access to an area I know has fire agate because I’ve found it there. I’ve read some about how it formed but I was curious if there is a way to use google maps/satellite imagery to find the most likely spots to find it in that area based on things like lava flows etc.
Hej, I'm here for advice on books to read. I want to learn more about load caring capacity of different soils, and layers underground. I'm a complete novice in this. Could this community recommend a book from which to start?
Whether it's your study space, outfits, or even the way you organize your notes, how do you all incorporate that geology vibe into your routine and surroundings?
That’s quartzite on top. Nice find in a canyon with big quartzite chunks about.
Im the type of guy to sift through the sands whenever im at a beach and found this beauty. Is it a rare find? Does it look like it has any minerals in it? My camera isnt too good but theyre is glimmer when you move the rock. What do you guys think?
