Lustre:
Adamantine, Pearly
Crystal System:
Orthorhombic
Name:
Named after Zoltan "Terry" (b. 1947) and Marissa (b. 1950) Szenics, American mineral collectors who discovered the mineral.
The szenicsite occurrence was an isolated area, approximately 1 cubic meter in size, wherein the szenicsite occurred in cavities in a matrix rich in molybdenite and Cu-bearing powellite. The cavities were filled with a clay-like material. Outside of the szenicsite zone, the mineralization changed from szenicsite to lindgrenite, with decreasing copper. Thereafter, moving further out, the mineralization was lacking visible copper content and consisted of powellite blebs in the ore. (pers. comm. Terry Szenics to Chet Lemanski, 2006).
Note: the type locality was originally erroneously given as "Tierra Amarilla".
