Abstract

Tatyanaite is defined as the member of the tatyanaite-taimyrite solid solution with Pt > Pd. It occurs in massive sulphide ore (chalcopyrite and subordinate pentlandite, pyrrhotite and cubanite) and forms large elongate grains (< or = 1 mm) and aggregates of smaller grains associated with Ag-Au alloys; other associated minerals include Pt-rich taimyrite, atokite-rustenburgite, paolovite, froodite, sperrylite, maslovite and galena. Tatyanaite shows cryptic zoning and characteristic polysynthetic twins; in reflected light it is pink with lilac tinge in air; reflectance is weak to distinct and anisotropy is distinct to moderate; reflectance approximately 50% (40% in oil); VHN (sub 20) 292-348. EPMA gave Pt 45.38, Pd 19.53, Cu 10.62, Ni 0.15, Fe 0.03, Sn 23.02, Sb 0.27, = 99.0, leading to the formula (Pt (sub 1.19) Pd (sub 0.94) )(Cu (sub 0.85) Ni (sub 0.01) Fe (sub <) (sub 0.01) )(Sn (sub 0.99) Sb (sub 0.01) ). Indexed XRD powder data are tabulated; strongest lines 2.283(10), 2.163(4), 1.369(3), 2??[&8869;]??030(2), 1.218(2), 1.143(2) Aa; a 7.89, b 4.07, c 7.73 Aa, V 248 Aa (super 3) ; Z = 1, D (sub calc) 13.55 g/cm (super 3) ; probable space groups Pmmm, Pmm2 or P222. The name is for Dr Tatanya L. Evstigneeva (1943-) of the IGEM, Moscow.
