The features of fluid inclusions and its geological significance in Zoujiashan uranium deposit

摘要

Zoujiashan uranium deposit, distributed in the volcanic-intrusive complex in Xiangshan area, south China, is a typical vein type one. The ore body is mainly controlled by the structures, and it is the pyrometasomatic deposit in genesis.rnAbout the source of metallogenic materials, Chen Zhaobo puts forward the double-mixing mode. He considers that the uranium comes from two main ways: the first is from the uranium-rich stratum which was switched to the acidic magma by anamigmatization and original fluid; the second is from the hydrotherm which is mixed with the original fluid and atmosphere water, dissolving the uranium from the uranium-rich stratum and the old uranium deposits when it raises and seeps. However, Du Letian thinks that the uranium is remobilized by alkali-alteration from the deep part. The fluid inclusions of Zoujiashan uranium deposit are studied in order to understand the features of hydrothermal fluid.
