Question
What mineral is this ? It is isotropic. This is a thin section of olivine gabbro
The image is a photomicrograph captured through a microscope, showcasing a thin section of a geological sample. The sample appears to be composed of various mineral grains, each exhibiting different colors and patterns due to their optical properties in polarized light. The minerals are interlocking and show a range of colors from pale greens to pinks and yellows, with some areas of dark, possibly opaque minerals. The variation in color suggests different mineral compositions and orientations. In the center of the image, there is a dark, irregularly shaped area that could represent a mineral inclusion or a void. Such images are used in petrography to study the mineral content and texture of rocks, aiding in the identification of their origin and history. Understanding these features is essential in fields such as geosciences and materials engineering.
