Zinchuk I. Geochemistry of mineral-forming solutions of gold-polymetallic manifestations of Central Donbass (by inclusions in minerals)

Object of study - vein ore mineralization of Nagolny ridge and Northern anticline, veinlet mineralization of Northern zone of small folds of Donbass. Goal - reconstruction of geochemical and physico-chemical parameters of mineral- forming systems and its influence on mineral composition and value of ore objects. Methods-mineralogical, petrogra- phical, mass-spectrometry of gases, izotopic analyses of car- bon, chemical, thermo- and cryometrical analyses. Novelty - the temperature and izotopic zonality of hydro- thermal manifesations was established, the leading role of CO2 regime in ore mineralization formation has been shown, and the usage of quantitative content of СО2 in inclusions as explorating feature has been proposed. The structures, perspective for natural gas prospecting were determined. Practical value - the results are used in creating of regional and local prospecting criteria for gold-polymetallic ores and natural gas.
