  1. Multiple, sharp, in-focus images taken ideally in daylight.
  2. Add in a scale to the images (a household item of known size, e.g., a ruler)
  3. Provide a location (be as specific as possible) so we can consult local geological maps if necessary.
  4. Provide any additional useful information (was it a loose boulder or pulled from an exposure, hardness and streak test results for minerals)

You may also want to post your samples to r/whatsthisrock or r/fossilID for identification.

Compiled clips from the USGS documentary on the 1964 Great Alaska Quake to accompany this song inspired by the Cascadia subduction zone rupture.

Plate Tectonics Simulation

Hi everyone! I’ve been working on a procedural plate tectonics simulation. This project started from my interest in geology and plate tectonics, and being curious about how different landscapes form on Earth. I wanted to share the latest version here and see how the overall evolution looks to you.

It seems like the Geological Society of London holds a careers fair every year, sometimes in London and sometimes somewhere else. This year it's in London at their HQ on Wednesday 4th Nov. Has anyone been before? Is it good? Are there companies to talk to who are hiring? Is anyone else going?

A tourist captured these images without thinking anything else from some distance away possibly from an observatory.

First picture 8:27 am

Second picture at 9:33 am

Third Picture with some collapse 10:21 am, he heard some rumblings at around 10:30 am as well. The pictures show what he thinks is rock collapse , before the glacier gave away from lack of support underneath. His explanation.

Picture 4 aftermath.

around 30 minutes later of the 3rd picture, the collapse occurred . CCTV time border at station 10:59.. an estimated 7 minutes to reach that place.

Quality loupe for my retiring geologist/mineralogist father

10 Upvotes

Hi all,

My dad is retiring and I want to get him some kind of cool rustic loupe triplet (I think that’s what they’re called??). A pocket magnifying glass that you flip out to inspect the gems/rocks etc

He’s been a geologist/mineralogist for 45 years and I thought it would be cool to get him a last little tool and like a leather case for it.

It seems like there’s not just shops for them online or like dedicated geology brick and motor places? I am not a geologist so I have no idea really about the magnifying glass scene.

If anyone can suggest cool brands, maybe with cool aesthetics and stuff? Something that’s like nice to look at and feel in the hand?

Sorry for ignorance and thanks for your help!

Similar to the earlier video I shared, but with some more insights into the local geology and highlighted things like remnant ice underneath the gravel of the valley floor, so I thought it was a worth sharing also.

I know that one of the first things that geologist looks for in a disaster is a geological map of the affected area. Below, are sources that I have so far been able to find of the disaster area. Most of the online publications can be found using Google Scholar. Unfortunately Reddit will not let me include links for some reason. If a person can not find the links, they can DM me.

What master's degree or doctorate in geology could I pursue to earn a high income without having to be in the field for several weeks or months at a time? I'm not looking for something that doesn't require me to be in the field at all, just something that doesn't require such long periods of time, like work on oil platforms. Something balanced between fieldwork and earning enough to ensure financial stability? (Images of the geology of my country)

While scouting for rock art/petroglyphs along the Yampa River Valley sandrocks in Northwest CO, I found some interesting features and formations & I was curious whether or not they appear natural? For example, some red pigment/staining in photos 4 and 5; almost perfectly circular indentations in photos 1, 2, 3, and 9; and interesting looking shapes alongside some similar colored banding/stratigraphy in a rock face in photos 6-8. Any thoughts at all are much appreciated!!
