Edoylerite, Hg32+Cr6+O4S2 a new mineral from the Clear Creek claim, San Benito County, California

Edoylerite is a rare constituent of a small prospect near the long-abandoned Clear Creek mercury mine, New Idria district, San Benito County, California. It is most closely associated with cinnabar, from which it is a primary alteration product, in a host rock composed predominantly of quartz, chalcedony and ferroan magnesite. Edoylerite typically occurs as acicular to stellate crystal groups on and around corroded masses of cinnabar. The mineral is canary yellow to orangish yellow, and possesses a yellow streak and an adamantine luster. The crystallographic, physical and optical properties of edoylerite are described. -after Authors
