While performing petrographic analysis in a rock composed mainly of plagioclase, pyroxene and olivine, I came across the mineral shown in the photo. Do you have any clues of what it could be?
The images of the rock in thin sections were taken with a polarising microscope. The top photo is the image with the crossed polarizers and the bottom photo is the image with one polarizer.
The biggest mineral (shown in photos) is about 800μm but there are also smaller ones.
