Name:
For the type locality.
It was published in 1989, abstracted in Am. Min. in 1992, is in the ICDD PDF database as 00-45-1399. "It was not submitted to the New Minerals Commission of the IMA at that time, although it was formally discredited (Burke 2006), as being possibly synonymous with hessite or petzite. Additional mineralogical studies were undertaken, therefore to clarify the chemical composition and crystal structure. In light of these new data, the mineral and its name were approved by the IMA Commission..., IMA No. 2009-080."
