Nice post! We usually encounter big limestone outcrops here in my area. I've only ever seen a dolomite from my laboratory class. If you could have done an acid test on the veins, I think you would be have a better idea if it were quartz or calcite! Then maybe a hardness test if it didn't effervesce, just to see if it's quartz or plagioclase.
Will definitely look forward to your other posts! I'm glad to see geology content here!
Thank you, I could make a thin section and look under a microscope but I suck at making thin section haha
Making a thin section is the worst haha especially the polishing part! I'd rather digitize maps than do that.
I always have a hard time not cracking the actually glass that holds the sample
I agree! That's the hardest, especially when the sample is already super thin
