Podiform chromite

This sample is light olive to brownish black. It exhibits a cumulate texture with anhedral chromite crystals in a matrix of serpentine minerals. The matrix weathers to moderate yellowish brown on uncut surfaces. Cut chromite crystals show alteration rinds that stand out because of a change in luster; dull in the rind, submetallic in the center. Chromite crystals are also highly fractured with the same alteration following the fractures.
