Rezumat: A unique association of native gold amalgam, cinnabar, native metals, cohenite and moissanite has been first found and described within Fadeevka ore placer knot. To study structure and composition of above listed phases a scanning electron microscope was used. Cinnabar and auramalgam are characterized by heterogeneous composition within one grain. A microporous structure is conditioned by fractality revealed in a number of mercury-bearing micro nuggets. Nonuniformity of composition, fractality of microstructure and presence of carbides in association with cinnabar are indicative of non equilibrium character of the association. Native metals are represented by spheroids of almost pure Fe and Cu and aggregated microflakes of Zn with carbonaceous nanospheroids on its surfaces. It was inferred that the association under study crystallized during the process of gas condensation of endogenous hydrogen- hydrocarbon fluids.
