Description

Wulfenite is a lead molybdate mineral named for an Austrian mineralogist. It is most often found as stubby, pryamidal or tabular crystals in a bright orange-red to yellow-orange color. It is found in many locations, associated with lead ores as a secondary mineral and often found Cerussite, Smithsonite, Hemimorphite, Vanadinite, Mimetite and other minerals. Among the more notable locations for finding Wulfenite are Pennsylvania, Arizona and Mexico.

Hemimorphite is a sorosilicate mineral that is chiefly associated with Smithsonite. It commonly forms crystalline crusts and layers and also massive, granular, rounded aggregates or finely shaped clusters of crystals. It may fluorescence a strong green in UV short wave light and weak pink in UV long wave light.
