anyone here a geology major?

I'm not. However, if you post the question or problem you are having, you might get some useful answers.

Civi/environmentall engineering. Sometimes some overlap

I took two semesters of Geology like 3 years ago.
Maybe I know what you need.

Well, it's about normative minerals in igneous petrology. So it takes a deeper understanding than a few intro classes or googling some shit.

That's where the google gods come in handy. Some around here are very close to these gods it seems. In posting a question, I wouldn't be surprised you get specifics on normative minerals in igneous petrology, flowage differential, convective Basaltic magma and whatever else.
