Hey dudes, /x/ here.

You're probably gonna want to beat me up for stating this, but is there any love in here for the feeling that granite expresses?

I come from a place where most old buildings are from granite stone, and it does give the town a strange mood, like if there is a perma-fog stuck in time. This rock has so much importance, that in pre-roman times there where a few cults that went as far as describing it as the primordial rock. They even spent quite a while looking for something they called the "Granite Seed".

So, I dunno. Granite thread? Mysticism + rocks thread?

Granite does feel nice to the touch but I dont know about all that other /x/ stuff.

Well it is a sialic mineral and probably the most typical rock of plutonic felsic igneous formations. Alongside it's metamorphic equivalent, granitic gneiss, it's the type of rock you'd expect to find in plenty of in and around cratons

The difference between the two is that granitic gniesses have experienced more compression and semi-melting than unaltered granitic intrusions, which makes sense considering how cratons sit for eons under continents without experiencing volcanism or tectonism. First pic related.

Contrast this to sialic rocks near mobile belts, which are constantly eroded into sediments and then lithified. (However, uplifting does create more vaccums for intrusion to occur, which simply does not occur in cratons).

On a slightly less autistic note, the mica, orthoclaise feldspar and quartz create a beautiful warm tone. Second pic related

It's found near the interiors of continents

>implying metamorphism requires partial-melting

I never said that. Cratonic materials undergo metamorphosis from sitting underground for a very long time, usually WITHOUT partial-melting or tectonism.

Contrast this to granite near mobile belts, which, compared to cratonic material, is more likely to be eroded and fragmented due to uplift exposure to the elements. It would just get eroded into sediment before it has a chance to undergo metamorphosis into gniess

>implying granite doesn't primarily form through fractionation and assimilation processes in arc/back-arc settings

See

>However, uplifting does create more vaccums for intrusion to occur, which simply does not occur in cratons

You're just paraphrasing my point

My point is that true granite rather than gniess will be under mobile belts, whereas gniess will more likely be in cratons. I don't see why you're trying to distort this

Exact quote from you:

>>The difference between the two is that granitic gniesses have experienced more compression and semi-melting than unaltered granitic intrusions

But go ahead and keep slinging jargon around, it'll impress the casuals.
