| Abstract: | There are widespread gold mineralizations in the southwest part of Xiaoqinling area, especially around Bayuan in Lantian County, Shaanxi Province. Some of them have been identified as gold deposits. The geological condition for the formatin of the gold deposits is discussed in this paper. It is suggested that the orebearing strata, magmatic activities, and the ductile-brittle faults of long-term history are the major factors controlling the formation of the gold deposits. The discussion is focused on such geological characteristics as attitude of the ore-bodies, ore types, wall-rock alterations and accurence of the gold minerals. Finally,according to the geochemical characteristics as well as the comprehensive analysis of the geological data, it is concluded that the gold deposits are of magmatic hydrothermal genesis and controlled by the ductile-brittle shear belts. |
