Szenicsite is a copper hydroxy molybdate mineral, named after husband and wife Terry and Marissa Szenics, American mineral collectors who found the first specimens. When it was first discovered in Atacama, Chile, it was thought to be lindgrenite. The occurrence appeared in an isolated area, which was about one cubic meter in size. The mineral occurred in cavities of copper bearing powellite and matrix rich molybdenite. These cavities were filled with a material resembling clay. Outside of the zone the szenicsite crystals grew, copper levels seemed to decrease, and the mineralization changed to

Szenicsite is a copper hydroxy molybdate mineral, named after husband and wife Terry and Marissa Szenics, American mineral collectors who found the first specimens. When it was first discovered in Atacama, Chile, it was thought to be lindgrenite. The occurrence appeared in an isolated area, which was about one cubic meter in size. The mineral occurred in cavities of copper bearing powellite and matrix rich molybdenite. These cavities were filled with a material resembling clay. Outside of the zone the szenicsite crystals grew, copper levels seemed to decrease, and the mineralization changed to lindgrenite. Moving further from the zone, the minerals growing seemed to be lacking copper, and consisted of powellite blebs in the ore. Szenicsite was approved by the IMA in 1993.
