摘 要: | Isoplatinocopper,a new mineral,has been found in a bistagite-pyroxene amplhibolite intrusive in the Yenshan Region,China,This mineral has been identified to be isometric and pale yellowish-white in color with a molecular formula of Pt4Cu5,α0=3.786A,specifie gravity=14.5,and no magnetism.In reflected light it is essentially isotropic,and yellowish-white in eclor with reflective power being 58% for green light,61% for yellow and 61.5% for red respectively,and its microhardness 127-220kg/mm^2.On the ground of the data on their chemical composition and crystal structure,Pt-Fe-Cu and Pt-Cu platinum minerals are divisible into two types,i.e.tulameenite which includes those with a composition of Pt5Fe4Cu-Pt2Fe3Ci2 and Pt2FeCu,and isoplatinocopper which possesses a composition of Pt4Cu4-Pt4Cu5.5
