Abstract. The composition and internal structure of geochemical fields associated to hydrothermal gold deposits within the Siberian territory were investigated. The concentric zonal structure of ore-forming geochemical fields embracing accumulations of Au, Ag, Bi, Pb, Zn, Cu, Te, As in ore bodies and their adjacent locations, and Ni, Co, V, Cr, Mn, Ba, Tiwithin the external margin of gold ore formations were determined. The thermometric properties of gas-fluid inclusions in minerals of hydrothermal gold deposits were described. The results specified not only high-mineralized but also weakly-salted fluids are involved in the formation of the deposit. The latter is subjected to both retrogressive boiling and the mechanisms of direct and reverse osmosis. In this case, ascending and descending fluids produce eddy fluxes during Earth rotation, where minerals of different composition are formed in this flow path. Produced spiral mineral-geochemical fields can be observed on satellite images as hierarchy circular pattern system. Both the analysis of anomalous geochemical field structure and satellite images make it possible to predict the ore bodies of different grades in complicated landscape geological conditions. IntroductionThe target problem in modern applied geochemistry involves such a fact as the low efficiency of existing geochemical methods used in mineral exploration. The reason is the depletion of easy-todiscover deposits, outcropping as primary and secondary dispersion haloes of tracer-element mineralization. Today, the prospecting of new deposits is being conducted in complicated landscape geological conditions where ore bodies are detectable only at great depths, and associated anomaly geochemical fields outcrop only as fragments, which, in its turn, is difficult to structure without additional information. Personal understanding of a geologist plays the major role in this case. This, however, does not foster reliable results and forecast. Current research is governed by the new geochemical data interpretation methods for mineralization forecasting in complicated landscape geological conditions. Anomaly geochemical fields develop during the formation of thermal fluid oregenerating systems, that is why, additional information on the development of hierarchic geochemical field system is based on the result investigation of gas-fluid inclusions preserved in hydrothermal minerals [1][2][3]. Temperature, composition and fluid salinity varies consistently in time and space, due to such phenomena as retrogressive boiling, direct and reverse osmosis and the blending of juvenile and vadose waters. Fluid migration scale during ore emplacement causes not only significant chemical rock composition alterations, but also changes its physico-mechanical properties. These alterations can be observed in the geochemical field structure and are recorded as line and circular patterns on spectro-zonal satellite images. Circular pattern hierarchy is easily identified within any landscape
