Thin-sections are carefully prepared glass slides suitable for mineralogical and petrology studies when viewed through a microscope. They are thin slices that have been carefully ground down and polished so thinly that light can pass through the mineral structures.

In transmitted light, thin sections reveal the texture and crystal shape of the mineralogy while through polarized light, the mineralogy is awash in color allowing for more complete mineral identification.
