...U. Kolitsch Abstract The previously unknown crystal structure of mckinstryite, originally described as Ag 1.18 Cu 0.82 S or (Ag,Cu) 2 S, was solved and refined using single-crystal X-ray diffractometer data collected from a sample from the Clara mine, Black Forest (Mo- K α radiation, CCD area...

...B. W. Robinson; R. D. Morton Abstract Mckinstryite occurs as late-stage, primary sulfide in the U = Co-Ni-Ag-Bi deposit of the Echo Bay Mine, N.W. Territories, accompanying niccolite, rammelsbergite, chalcopyrite, bornite, covelite and early dolomite. Electron microprobe analyses reveal...

...Brian J. Skinner; John L. Jambor; Malcolm Ross Abstract Mckinstryite, Cu (sub 0.8+x) Ag (sub 1.2-x) S, where 0 < or = x < or = 0.02, was found on a specimen collected in 1907 at the Foster Mine, Cobalt, Ont. Mckinstryite is orthorhombic, space group Pnam or Pna2 1 , a = 14.043 + or - 0.005 Aa...

...,As) 2 S 11 ], famatinite (Cu 3 SbS 4 ), proustite (Ag 3 AsS 3 ), and tetrahedrite. Gold occurs as Au–Ag alloy and uytenbogaardtite (Ag 3 AuS 2 ). Chalcocite, native gold, stromeyerite (AgCuS), rare covellite and mckinstryite [(Ag,Cu) 2 S] are the latest phases, of supergene origin. Microthermometric...

...- and Au-bearing mineral association is represented by acanthite, argyrodite, polybasite, pearceite, stromeyerite, mckinstryite, and jalpaite. Abundant acanthite occurs commonly associated with gold and silver; copper enrichments were detected and interpreted as nanoinclusions of Cu-bearing minerals...

... carbonate on quartz grains, as isolated grains of jalpaite Ag 3 CuS 2 , stromeyerite AgCuS, mckinstryite (Ag,Cu) 2 S, and as atacamite Cu 2 Cl(OH) 3 , which rim and replace detrital carbonate grains.

... below 200 ºC (stephanite, uytenbogaardtite, jalpaite, stromeyerite, mckinstryite, among others). The end of the most productive stages (3, 4, and 5) is marked by the precipitation of stephanite at temperatures below 197 ± 5 ºC, but precipitation of residual silver continues through the waning stages...

Gold-silver-bearing minerals include electrum, aeanthite- aguilarite, polybasite-pearceite, pyrargyrite-proustite, jalpaite, mckinstryite, hessite, an Ag-Te-Se-S mineral, and tetrahedrite.The...

..., bornite, and tennantite (ca. 1-4.3% Ag) are the major ore minerals and are associated with minor sphalerite, digenite, covellite, chalcopyrite, wit-tichenite, native silver, acanthite, stromeyerite, mckinstryite, jalpaite, and the ruby silvers. Pyrite and marcasite are subordinate constituents of the ore...

...B. W. Robinson; H. Ohmoto Abstract At the Echo Bay mine, vein type U-Ni-Ag-Cu deposits occur along NE-SW-trending fracture zones in ca. 1,800 m.y. old andesitic tuffs. The temperatures of mineralization suggested by the occurrence of native bismuth and mckinstryite, the fluid inclusion filling...

... minerals in the ores of Au-Ag (fahlore) type are represented by scarce and impoverished impregnation of galenite, tetrahedrite-freibergite, sphalerite as well as chalcopyrite, boulangerite, acanthite, polybasite, mckinstryite, and silver. The gold contents are 800–840 and 520–610%. Some different forms...
