Strashimirite (IMA symbol : Ssh[7] ) is a rare monoclinic mineral containing arsenic , copper , hydrogen , and oxygen . It has the chemical formula Cu8 (AsO4 )4 (OH)4 ·5(H2 O) .[8] [9]
This mineral was discovered in Zapachitsa (Zapacica) copper deposit, Svoge , Sofia Oblast , Bulgaria in 1960, by Bulgarian mineralogist Jordanka Minčeva-Stefanova . She named it after Strashimir Dimitrov (1892–1960), Professor in Mineralogy and Petrography at Sofia University "St Kliment Ohridski", Bulgaria.[10] The International Mineralogical Association approved it as a new mineral in 1968.[11]
It occurs as a secondary mineral phase in the oxidation zone of copper arsenide deposits. It occurs associated with tyrolite , cornwallite , clinoclase , euchroite , olivenite , parnauite , goudeyite , arthurite , metazeunerite , chalcophyllite , cyanotrichite , scorodite , pharmacosiderite , brochantite ,
azurite , malachite and chrysocolla .[2]
Although it remains quite rare, strashimirite has subsequently been identified in a number of locations including: Novoveska Huta in the Czech Republic; on the west flank of Cherbadung (Pizzo Cervandone), Binntal,
Valais, Switzerland; in Kamsdorf and Saalfeld, Thuringia, Germany; the Clara mine , near Oberwolfach, Black Forest, Germany; in the Richelsdorf Mountains, Hesse, Germany; Cap Garonne mine, near le Pradet, Var, and Triembach-au-Val, Haut-Rhin, France; Wheals Gorland and Unity, Gwennap, Cornwall, England; the Tynagh mine, near Loughrea, Co.
Galway, Ireland; the Majuba Hill mine, Antelope district, Pershing Co. Nevada, US; and the Centennial Eureka mine, Tintic district, Juab Co., Utah, US.[2]
