The origin and mineralization of the tin-bearing granites of the Krusne hory (Erzgebirge) province: A 3-dimensional approach with new data on ore deposit zoning around a granite batholith

摘要

The new summary of metallogeny of the Erzgebirge/Krusne' hory granite batholith (Sn, W, U, Pb-Zn, Ag, Bi, Co, Ni, fluorite and barite) in Central Europe shows that the symmetrical and synchronous mineral zones around the granitic magmatic foci of temperature and pressure do not exist. The irregular distribution of mineral districts is controlled by the lines of emplacement of younger (YIC) granites, by major deep-seated fault zones and by the local lithology in the envelope. Variously mineralized crustal segments were exposed to different fluids of various origin after the emplacement of granites. This is the main cause for the irregular distribution of ore-bearing assemblages in relation to the granites which early workers interpreted as horizontal mineral zoning.
