The Trace Elements Geochemical Characteristics and Formation Mechanism of Xiongjiashan Molybdenum Deposit, Jinxi, Jiangxi Province
The Xiongjiashan Molybdenum deposit are mainly in the form of molybdenite, which enriched in the rock strata and space of the broken and fractured, and formed molybdenite ore body along the direction of trending vein and stockwork. Preliminary studies suggest that it was the magmatic hydrothermal quartz vein-type deposits. And the con- temporary magmatic rocks have the same source in the region, what’s more, the tectonic environments of caledonian tectonic and Yanshan tectonic was certainly similar, anything else the tectonic evolution of this area may also be a manifestation of repetitive. Trace element characteristics of wich show that the magmatic rocks are from the partial melt mixture of lower crust and upper mantle, such as the crust-mantle mixing. And also it was under the continent-continent collision tectonic environment. And the contents of Eu anomaly that is not the same degree, which corresponding to different levels of the miscibility of the crust-mantle. Extremely favorable environment and complex structures, which was in favor of forming the Molybdenum deposit by the fluid from the formation of rock. The mineralization fluid is closely related with the multi-stage veins that corresponding to the magmatic activity, which carrying ore-forming ele- ments as Cu, Mo and the mineralizer elements of S and so on, lately magmatic evolution ended and the Xiongjiashan Molybdenum deposit formed.
