1913Jrnl. Chem. Soc. CIV. ii. 516 Maucherite, a new nickel mineral from Thuringia... This new mineral, which was at first mistaken for rammelsbergite, occurs..in veins..in the copper-shales..at Eisleben, Thuringia. 1940Mineral. Mag. XXV. 570 A physical, chemical, and preliminary structural study of maucherite..from Eisleben, Thuringia, and Sudbury, Ontario, and temiskamite..from Elk Lake, Ontario, shows that these minerals..represent a single mineral species. 1963Mineral. Abstr. XVI. 263/1 Syntheses from nickel and arsenic were carried out by means of dry thermal procedures... At arsenic vapour pressure, Ni5As2, maucherite, niccolite, rammelsbergite or paramelsbergite [read pararammelsbergite], are formed depending on the temperature. |
