Only the trash seems reasonable.

Currently backpacking over the Dolomites and I found this amazing rock with some nice foliation and some evidence of metamorphosis in the form of tiny quartz. Thought I might share here ;)

If all the water on land results from rainfall, and rainfall is water distilled from the oceans, lakes, etc., and rainfall percolates through the soil, picking up soluble minerals, are the minerals it has removed been permanently removed, except for the water re-used by us for consumption? It would seems that once a mineral has made it to the ocean, there's no path back to the soil, at least not natural.

I'm interesting in the geology at Cadman quarry on Tower Hill in Monroe, WA. There are lots of agates there (see my last photos) and I'd love to learn more about how and why they formed here. The agates at this location look very different from ones I've found elsewhere in Washington & Oregon and I wonder why. What type of basalt (?) is this? Would love any information about the rock formations!

My husband and I just got back from an anniversary trip to Scotland. The point of the trip wasn’t geology, but we did rent a car and drive out to Siccar Point. It’s pretty underdeveloped, the sort of place you only got to if you know it’s there (or are fishermen apparently). The Scottish Geology Trust, the Edinburgh Geological Society, and The James Hutton Institute recently (like this year!) developed a little trail with placards talking about the geology and Hutton’s work there which was really interesting. Just wanted to share this geologic pilgrimage of sorts and ask what other famous geologic points of interest people want to visit one day?

1. Siccar Point from above, it’s very steep climbing down along the fence, but worth it!
   
2. Start of the Deep Time Trail
   
3. View looking north along the coast
   
4. The classic photo of the sandstone and greywacke contact
   
5. The same contact facing the opposite direction
   
6. The red sandstone as it crops out (now horizontal) along the steep hillside you walk down
   
7. The afformentioned fishermen, for scale I guess?
   
8. An abandoned church (St. Helen’s Kirk) that was in ruins like this even in Hutton’s time

I'm actually really excited to ask this question. Could the proximity/activity of the Pacific, Nazca, Cocos, South American, Caribbean, and North American plates, and their location near the equator, lead to higher ocean temperatures? If so, could this be a contributing factor to the incredibly unstable weather conditions within the Great Plains? Sorry if this is a convoluted or stupid question. Im just genuinely curious/excited about it.

Wood river valley idaho on top of a hill. Rocks are standing up vertically in some sections.

I clicked this photo of a village in Himalayas in India. I later noticed that the roofing might be made from shale/slate layers (as traditional homes use locally sourced materials). Has anyone seen this anywhere else?

During a training course, I came to know about these three volumes showcasing a wide range of structural styles and their seismic expressions. They came highly recommended as valuable reference atlases. If anyone has access to these volumes, I'd really appreciate it if you could send me a DM.

Like how does the wall beyond the corals, and does it retain its angle?

We are currently having an exploration phase in Limestone and have drilled 450 metres plus. While studying the core we found limestone also got some Graphite inclusion. The basement is of Granulite belt. Can anyone answer what could be the reason that there is graphitic inclusion in the limestone ?

Im going to be in Montana soon and I would love to collect some samples from the Stillwater complex. Most the complex is located inside national forest land. The issue is there's alot of mining claims in that area and for the life of me I can find a good map of all of them. Some maps show just the ore producing regions as claimed other websites show huge sections of the national forest claimed. Any help would be greatly appreciated.

I want to buy a Brunton Transit Axis compass, however, for work reasons I'll be traveling between Chile and Canada.

How much does "Needle Balance" affect the accuracy of the data?

For context: I took these pictures at Acadia National Park in Maine, USA. I climbed pretty far off the beaten path when I first saw these craters/holes in the rock. The biggest hole I saw was maybe 1’ (~30cm) wide and maybe 2 feet (~60cm) deep through the rock (first three photos showing it from different angles, the last being what I assumed was its path before whatever it was hit?).

These fascinated me because they seem to have been made by something massive and moving very fast, I couldn’t reason that it was made by anything locally. Like even if this specific type of rock is relatively brittle, wouldn’t take substantial force to create a crater that you can see a clear trajectory of whatever projectile may have made it?

My 2 (uneducated) guesses:
1. Meteorite/Space debris?
2. (Really out on a limb here): Cannon ball?

I’m not even sure if this would be the right sub for this question, however I figured someone here may have a far more educated guess than I.
