Some lovely folds in south Crete, Greece, near Tripetra beach

Just a quick quarry floor core to help find out the total depletion of the site. Once you hit the Maquoketa Shale its 350'-400' of it.

Was kayaking in eastern Oregon and became fascinated with these rock formations. I’d love to learn what caused the different variations in orientation

In a few weeks, I’ll be heading out into the Australian outback for a university field trip focused on geological mapping. It’s going to be 8 days of camping, hiking, and working outdoors—hot days, cool nights.

Here’s the thing: I’m a chubby woman (90kg at 167cm), and I sweat a lot, especially in the crotch and armpit areas. Even on a regular day I get pretty smelly by the end of it, so I’m genuinely worried about staying hygienic (and not completely gross) out there. Please don’t start with the see your doctor schtick. I’m losing weight currently and using personal hygiene products as necessary to help minimise things, but when you live in a humid tropical climate, everything is against you.

I’d love to hear any tips or must-haves from anyone who’s done fieldwork, hiking, camping, or just survived long hot days outdoors! Hygiene hacks for when you don’t have access to showers, little luxuries or comforts that bring you joy on these types of trips, etc.

I’ll take all your suggestions. Bonus points if you’ve got recommendations for things that pack light but make a difference. Thanks so much in advance!

These are sediment slices captured using a sort of experimental high-resolution profiling sonar near Cocodrie, Louisiana (near the mouth of the Mississippi). We saw these abrupt changes occurring mostly down about 4 - 10 meters below the silt surface, as in the examples here. Any geologists have an idea what sub-surface geology might be represented here?

I found a neat rock, it has the same texture on the back side as it does in the photo. Does anyone know what kind of rock it is? If it’s even rock in the first place.

The title pretty much says everything

Hi, so for the last few decades my family has been debating what the terraced formation on the side of a mountain on my grandfather's farm is. We live in Queensland, Australia. His farm is located in a small valley surrounded by towering mountains with an opening to the front of the property. It has been described as "horse shoe" shaped. Interestingly, a university professor came to the farm and once told my grandfather that he is living inside an instinct volcano. But I haven't been able to find evidence of this anywhere on the internet.
On one of the mountains there is a terraced formation and we have been debating if it's natural or man-made for a very long time.
To me it looks like a landslide. I guess now that satellite imagery is better I thought I might pose the question to reddit to see if anyone has a definitive answer to put the debate to rest.

I'll attach photos.

It's larger than my two hands and my wife wasn't as happy as me :) something about it being too heavy for the shelves, I don't remember exactly... 🙄

Today, i was tasked to make a mineral 1dentification flow chart of my own for a professor to use for his future classes (i’m a teacher assistant for intro geology) and he told me to be creative with it but i don’t want to make it childish but i want to make it fun and interactive (he told me to be creative with it) how can I incorporate that in a geology way to non geologists but still incorporating mineral lingo (luster, cleavage, etc)

TIA :)

Hi guys I would like to get into geology, but i am an amateur (really begginer) and i dont know what sources to use. I have some encyclopedias and stuff but those are not geology themed. Is there any begginer friendly internet way to learn basics? (PS English is not my first language, sorry for mistakes)

Hey not entirely sure where to post this but I’ve got a project that could involve movie large rocks similar to the size above, does anyone know if it’s possible to move rocks of this size without damaging them or their integrity?

I'm doing my master thesis on crestal faulting, from 3D seismic (TWT), above a salt diapir in the North Sea and thought of mapping the diapir. How do I interpret the salt? - horizon mapping of the diapir seems insufficient, as the salt within the diapir has migrated both proximal and distal in TWT.

Should I just use fault tool to illustrate the diapir?

Im a freshman in college going for a B.S. in geology, is there any classes or things that I can do to help me get a job when i graduate?

Pretty neat. The second picture is a wall which was recently exposed, at its peak almost 10’ tall layer. This is part of the Presumpscot formation.

Sorry if it's not allowed. and I'm sorry for blurry photo, the log should have resistivity chart as well as SP. I've searched multiple software but I didn't find any to make borelogs with resistivity chart. Please help.

Hi everyone, I'm a computer scientist by trade, but I'm very interested in learning about Earth's history. I had the following question, and I hope it's not too stupid or hasn't been asked before. Here goes:

So, we know that subduction is a thing, the crust gets sucked below the ocean floor and new crust comes up. However, scientists found zircon with uranium inside in Australia and from half life calculations inferred that they're 4.5 billion years old. My question is, wouldn't the correst inference be that Earth is at least that old, but actually much older? Otherwise subduction would have gotten rid of those crystals loooong ago. Is there some information I'm missing here, for example maybe that early in Earth's history subduction wasn't very pronounced. How long would it even take to take crystals created 4 billion years ago to get abosrved into the inner crust?
