Schematic of Martite Microscopic Image

Caption

A schematic highlights the trellis or basket-weave pattern composed of tiny crystals of the iron-oxide mineral hematite that is diagnostic of the hematite pseudomorph, martite. The image at left is a reflected-light microscopic image in cross-polarized light. At right is an electron backscatter diffraction produced from a field-emission scanning electron microscope. Utah State University scientists use these images to accurately identify mineral types and determine the rock’s geochemical and tectonic histories.
