Mineralpedia Details for Poughite
Poughite
Named in honor of Dr. Frederick Harvey Pough of Nevada, USA, who was a mineralogist and gemologist and made numerous contributions to those sciences, and is most known for authoring the Field Guide to Rocks and Minerals. Poughite is an uncommon mineral found in Honduras, Mexico, the USA, Chile, and Japan among only a couple others. It is a product of the alteration of pyrite in oxidized hydrothermal Au-Te minerals at its type locality at Moctezuma, Mexico.
