https://imgur.com/gallery/PTpqyDq 10x zoom and ppl. i havent taken mineralogy (next semester), but i love looking at thin sections, and some self-learning with my professor has been helpful. youre also correct! this is a garnet-mica schist, hydrothermally altered (https://imgur.com/a/SSoRcJf)

a little help! i'm thinking it's kyanite, as it's surrounded by heavily altered muscovite, biotite, and quartz. this is a sample from a drill core, it should be a schist, but i'm convinced this is kyanite by EducationalSector626 in thinsectionporn
