We have finally reached the Anthropocene epoch!

It said that "Had it been approved, the official declaration of the new Anthropocene epoch would have taken place in August 2024, and its first age may have been named Crawfordian after the lake."

Found this on the bank of Apalachicola river when visiting Torreya State Park in North Florida. What causes these lines? This area is predominantly limestone but idk if this is limestone

My mom went to an estate sale and bought me an old jar of rocks. I opened the jar and some dust from the rim fell out. I then realized there was a sticker on the jar that had the names of the rocks. There were about 10 different kinds, and one was uranium ore.

As someone with a lot of health anxiety, I am now freaking out. I do not know if I breathed any dust or not. I don’t think I did? Everything I read online either says I’ll be fine or it says I’m going to die. I’m just looking for more opinions on what the likelihood of this being impactful to my health would be.

On a recent field trip I collected some ulexite, halite, calcite, and kernite.

What is the best way to preserve these. I heard hairspray and clear nail polish. Is there one better than the other?

Thank you 😊

Essentially what's in the title. I'm curious about how things form. The location is between San Diego and Ramona. Thanks in advance!

I'm back with another dumb question

So I've heard that the energy radiated away from an earthquake is much less than the total energy of the event, why is that?

Hi, I’m studying a levels biology, chemistry and geology. I’m predicted ABB.

The degrees for human biology and biomedical science have content that I find more interesting but the earth science degree has better opportunity’s for careers after the degree. Can someone help me decide which one to go for?

On the foreshores of Wollongong, New South Wales, Australia.

So I inherited a massive collection of local rocks. Most of them are obvious what they are. Some are more obscure and various groups have offered many different opinions on what they might be, these are the ones I would like identified.

There is a local University near me that has a geochemistry department, with a laboratory.

I’ve been thinking about sending an email to see if they will analyze some of these rocks.

My questions:

Will they want reimbursement?

Will they have to destroy the samples?

Is this even something they would consider?

Do you have any advice for how to ask them?

Thanks

I'm 28 with a full time job in a completely different field. Can any veterans or experts in the group help me with sources or guidance to study Geology on my own? Is it even possible, this is the only option i currently have. Got a quick learning curve, I can digest tough literature eventually. Side note, I don't want to pursue it as a hobby but equivalent to academia.Thanks in advance. Background: Material science

Can someone explain to me in layman terms why the drop in salinity caused by the melting of the polar ice caps is weakening the Gulf Stream

Hello! I was in a field reconnaissance for mineral exploration and found a huge quartz (white) blocks with thats darks red iron oxidized portions. Anyone think that have potential for some ore mineralization?

I’m traveling in Moab Utah and I’m really confused on the difference between a petrified sand dune and sandstone. I tried googling and couldn’t find anything.

I was at the same glacier (helm glacier) just three years ago, and that massive rock pile wasn’t there, it was just white. The pile has appeared within 3 years. if you look on Google Earth it’s not there. At first I thought that it was just exposed rock because of the melting, but I went to check it out and there is definitely glacier under it. My only other two theories are that there was a large rock fall in the area, or that the glacier has lost so much thickness that it exposed an old rock fall.

This is one of my favorite gemstones but it’s also super expensive. I was wondering if a low quality version of it exists and how much it costs ? Also if anyone knows where to buy it from a reputable source that would be dope.
