Abstract
A unique placer deposit of platinoids Konder has been in operation since the 80s of the last century by the artel of the Amur prospectors. During this time, the placers of the rivers Konder and Uorgalan were worked out. A number of publications deals with the regularities of the formation of the Konder placer and the similary-named ultramafic massif. The researchers described in detail the morphological features of the platinum group minerals (PGM) of the indigenous non-industrial manifestations in the ultrabasic Konder massif. It has been established that the isoferroplatinum formed in the decay of a solid solution of the composition (Pt, Ir, Os)3(Fe, Cu) is of primary importance in the indigenous sources of the Konder and is of different morphologies: homogeneous idiomorphic, drop-shaped, irregular and «porous». Isoferroplatinum (Pt3Fe) of the Konder alluvial deposit turned out to be very heterogeneous both in iron saturation and in the content of impurity elements of the platinum group of PGE.
