XRD Confirmed

Blue granular mass of mostly Cerchiaraite-(Fe). (XRD). Since the discovery, analogues of Cerchiaraite were also found at Big Creek and again at the type locality (Cerchiara mine). As such, the original Cerchiaraite was renamed Cerchiaraite-(Mn).   The abstract of Cerchiaraite-(Fe) in Mineralogical Magazine v. 77 n. 1 states that the mineral occurs as aggregates of irregular blue prisms at the Esquire claims. This specimen from the Gun Claims also contains crystalline blue compact aggregates. The prism ends can be seen as crude grains in the matrix. It is associated with yellow barite. Specimen has been analyzed by XRD by one of the others of the original Cerchiaraite.

Type Locality,Author's Material

Carchiaraite-(Fe) is one of the latest new interesting barium minerals from the Big Creek area. It shares type localities with the Cerchiara mine and Esquire #7 claim. It forms by the alteration of sanbornite-quartz rock and occurs as dark blue micro prisms in matrix barely visible with microscope. May be associated with Bazirite, Calcite, Titantaramellite, and Tobermoreite. This is authors material. Several authors provided the analysis of this new (2012) mineral including A. Kampf, A. Roberts, K. Venance, C. Carbone, G. Dunning, and R. Walstrom.
