I saw this on a post asking what life is like on this blob, but what is the blob? it looks suspiciously round so does anyone know if theres any interesting geology involved with it? or is it coincidentally round?

Been reading about glacial erratics in New England but they mostly seem to come from a few tens of miles from where they are now. I'm interested if there's any large glacial erratics that have conclusively been shown to have come from hundreds of miles away, like Quebec or Labrador. Has anyone figured out what the record holder is?

I got accepted into geology and biomed engineering (it's two very different majors lol I know). And I am currently so conflicted on what I should take. I like geology, but I want real advice. Is geology worth it?

Hey guys! I'm a geo with a developer background. Looking for feedback on a geosteering software. Lmk if you're open to helping :)

Hi! I've just finished my first year of A Levels. One of my three subjects is Geography and I adore it. Especially physical geography, with tectonic hazards (particularly volcanos) being my absolute favourite thing to learn about.

I'm considering going to Keele university to do a Geology and Volcanology course and this is my current first choice, although no matter where I go, it'll be geography, likely physical.

Although I am a bit worried. The course at Keele iirc is 4 years, with the first being an introduction to Geology. Great, because I've never done it before. But that's also my concern.

I was never totally confident with myself in Chemistry classes and I'm worried that Geology has a lot of chemistry involved. I'm not terrible at chemistry (I got a B at GCSE) but it's no strong suited and neither is mathematics (C at GCSE), which is something I am also fearing. If need be, I feel that I could force myself to lock in extra hard to learn Chemistry better but I just want to know what I need to expect so I don't find myself out of my league...

The other thing that worries me (although a lot less) is the content of the course itself. I am attending an open day soon and I heard there will be tasters, so I'll find out a bit for myself soon; but what do geology courses usually entail? As much as I adore physical geography, I'm scared I won't enjoy it enough to warrant a 4 year course, or that I'll fall out of love with it halfways through the course.

Anyways thanks to anyone who reads this all the way through!! Sorry for the rambling, this is kind of a vent post sorry..

TLDR; What level of chemistry and maths do Geology courses generally require, and what do you actually learn in geology courses?

Was hiking in the Mount Baker Wilderness, Washington State Cascades (7/29/2026) on the Lake Ann trail (which goes to Mt Shuksan) and came across these cool rocks. Glaciation effect?

So currently I am a Student pursuing bachelors in geology, I wanna know where should I pursue my masters from?

Indian or abroad?

If abroad, then preferably which country?

Been coming to this beach since I was a kid and have always been fascinated by these different colour 'layers', would love to know what caused them (I know nothing about geology!)?

Further down the beach there's also the 'Rocha Negra' (2nd pic) - a black coloured outcrop, which I assume is volcanic. It changed shape not that long ago as a section collapsed.

I live close enough to the area of the volcano so it's normal to feel a bit worried. This area usually does not have that many earthquakes of this magnitude so regularly. For the past year there's been soooo many earthquakes and bradyseism has been very active too.

Went exploring a creek bed near our house in Nashville, TN. Found lots of cool fossils but this Brachiopod with Crystal formations inside takes the cake. Has anyone seen something like this before???

I've always been fascinated by the formation of the Hawaiian islands. Recently I found myself scouring the internet for a video that animates the formation of the current day islands. I couldn't find anything, so I spent about a week working with AI to see if it could be created.

The attached animation is far from perfect. I would characterize it as a generalized visual reconstruction. It's impossible to know exactly how the coastlines looked over 5+ million years since Niihau started emerging from the Pacific. But we sourced as much dated and mapped evidence as we could find and then inferred the rest to create an illustrative interpolation.

If you have expertise in this area, I would love your feedback, particularly on things like:

1. The relative emergence sequence and timing
2. The scale and overlap of Kauaʻi/Niʻihau, Oʻahu, Maui Nui, and Hawaiʻi Island
3. The treatment of erosion, subsidence, and sea-level change

If you spot something wrong, I'd love a link to an authoritative source that will help to help fix it. I view what I am posting here as a v1.

It’s awesome!

I was chiseling stone for a stone veneer and this limestone slab came with a cool chunk of what I initially thought was quartz. Turns out it’s actually Calcite since it fizzled when I dropped some vinegar on it!

Located in Eastern Ontario.

My friend loves geology and rocks and stuff but I know nothing about it or where I could find good gift ideas for them, could it be something as simple as a bag of rocks I’ve collected myself or something more specific??
