This is a thin section of dunite, a rock made up almost entirely of the mineral olivine, as seen in cross-polarized light through a Leica Z6 APO Macroscope. There is a band of black mineral grains to the left of center of the image that is a cumulate layer of the mineral chromite - in the magma chamber from which these minerals crystallized that band of chromite would have originally settled out in a horizontal layer. The width of the entire field of view visible here is just under 2 cm.
