Type Occurrence of Tianhuixinite
General Appearance of Type Material:
nanometric crystal aggregates, 10–70 µm in size, intergrown with virgilluethite.
Place of Conservation of Type Material:
Parts of the cotype samples have been deposited at the University of Arizona Alfie Norville Gem and Mineral Museum (catalogue nos. 22072) and the RRUFF Project (deposition nos. 220024)
Geological Setting of Type Material:
The Summit group of claims consists of a number of adits, shafts, pits, and trenches, many of which are rich in fluorite. Hydrothermal solutions originating from a granodiorite produced ore bodies localized in limestone units beneath impermeable shales, a process subsequently accompanied by silicification, the latter leading to the formation of jasperoids. The Summit group was one of the largest lead, zinc, and silver producers in the district (McLemore et al., 2001). The upper levels of the mines were highly oxidized and have been completely mined out. A more detailed summary of the geology and mineralogy of Cookes Peak mining district is presented by Simmons (2019).
