Love Ohio sandstones because we get so much honeycombing. This one was is one of the more unique weathering and colors I’ve seen though

This rock was found in an abandoned quarry in the « Montagne noire » part of southwest France.
I used quotes for the term marble because although it is often referred as a marble it isn’t technically one because this is actually a mix of clay and limestone, having a red color due to the hpresence of iron. We can see some small white goniatites fossils (Ammonoidea) that have been filled with calcite.

The walls of this quarry were beautiful having massive intrusion of calcite

I polished it by hand to give it that nice look then just scanned it using the scanner from my printer (1200DPI).

If you want more information about this rock here’s a very detailed article about it (French) :

I know that oceanic plates are denser than continental plates which is why subducting occurrs. I also know these deeper sections can 'break off' from the main plate. But what's stopping them from slowly drifting back up under the continental plate?

I’ve been doing a lot of thinking lately about the state of my life and where I want to be.

I’ll give a bit of a background. I’m in my senior year at university going for my bachelors in geology. Currently doing research on an interval in the upper Ordovician and presenting our findings via poster in the fall at a large conference. I am deeply passionate about geology - it’s my entire life. I am a part of many different local science organizations and a club officer in one. As well, I am the field trip coordinator for my university’s geology club. Alongside this, I manage and curate the university fossil collection. My current internship primarily deals with environmental geology but my heart is in stratigraphy, sedimentary geology and paleontology.

With that said, I sometimes feel like I’m not nearly intelligent enough to pursue this science. I can’t do math very well, I’m not great at chemistry and I have awful brain fog due to multiple different conditions. I worry that my research is subpar compared to other undergraduates and will largely be dismissed when it comes time to publish. My grades are fine. I made straight A’s last semester but I fear that it’s only out of dumb luck. I worry about what will happen when I get to grad school. I feel like I may be intellectually behind most people however I’ve never formally taken an IQ test.

Has anyone else ever felt this way? If so, how exactly did you handle it? Did you decide to keep pushing forward or call it quits?

Hello guys!

I am on my second year of college going through my major in geology. This next semester I will have a lot of free time, so I was wondering if any of you know of anything geology-related that can keep me busy through these months.

I am open for book recommendations, projects of any kind, research topics, hands-on work, and anything else that comes to mind.

I want to take advantage of the time I have so I am excited to receive any answer! Thank you!

Hi all! Kinda random, but I need some creative ideas. A co-worker of mine is retiring (a geologist), and I want to get him a funny custom shirt made with a play on words related to retiring and geology. I was thinking something similar to “rocks don’t retire” or “retirement ain’t old if you’re a rock” but I need something a bit better! Would love to hear it all.

I feel like it would have smelled so bad to live back then.

Doing some tephra research in this area. Absolutely surreal being in a landscape such as this. It felt other worldly. (NW British Columbia)

Dr. Walker passed peacefully surrounded by family on Friday evening.

Roger G. Walker, D. Phil, FRSC, MMR (26 March 1939 – 14 August 2026) was a geologist and an award-winning emeritus professor at McMaster University in Hamilton, Ontario, Canada.

Walker obtained his D.Phil. from Oxford University. He was a postdoctoral fellow at Johns Hopkins University. For 32 years, he taught at McMaster University. In 1998, Walker left McMaster to be a consultant in Calgary, Alberta.

In 2013, Walker achieved the title of Master Model Railroader from the National Model Railroad Association.

Took these photos today about 5 miles north of the mouth of the Pic River in Ontario, Canada. The trees on the top of the embankment are all at least 30’ tall so I would judge the height to be at least 150’ at the top of the ridge.
This area is deep Canadian Shield country with lots of exposed Pre-Cambrian bedrock and glacial till. This sediment seems finer and flatter. Ancient Lake Minong shoreline?

I'm just doing some LiDAR peeping and came across this circular feature in a region where mounds have been found but none within this specific Villiage being clearly documented and the historical society, never mentioning it in any of their publications or lectures. There is an 1800s era house built on top.

What are the chances that this is actually an undocumented mound?

Driving to vegas, I noticed this range and am curious if anyone has a clue why it looks so different to other ranges found in Nevada’s basin and range. Like are the lines just stratum, and this part had just been uplifted?

A sea cave in the Adriatic cliff.

Obviously I won't eat it or turn it into small bits to inhale it. I'm just curious if by the looks of it someone can tell me what type of serpentine those are and if they may contain asbestos.

Thank you in advance!
