This article is devoted to the problem of biogeochemical peculiarities of plant of mining gold ore deposit zone. The tissues of larch (Larix cajanderi Mayr.) were the object of our studies using of X-ray fluorescence elemental analysis with synchrotron radiation (SR-XRF) method. Large possibilities of SR-XRFA, along with the simple preparation of biological samples, allowed us to carry out valuable biogeochemical investigations in Kuranakh Gold Mining area (Russia, Yakutia). New data on the accumulation of biophilic microelements Cu, Zn, Mo, chalcophilous Ni, Pb, Ag, As, Sb, rare lithophilous Rb, Sr, Zr, Y, Nb, scattered chalcophilous Ga, Ge, Se, Cd, Te, Tl in the tissues of larch (Larix cajanderi Mayr.) of gold ore deposit areas and of gold wastes tailings were obtained. The changes of elemental composition of plant under technogenic impact in area of tailings and in areas of natural geochemical anomalies of ore deposits is very significant to assessment ecological risk of technogenic impact in mining areas.
