江西相山CUSD3钻孔铀矿化蚀变带元素活动性探讨
The Element Mobility Study of Uranium Mineralization Alteration Zones in Xiangshan, Jiangxi Using the Drill Core CUSD3
摘要
Abstract
U mineralization section of CUSD 3 drilling core n Xiangshan of Jiangxi was selected as an objective in this study.Based on core observation and petrographic analysis,alteration zone was divided into five belts,which are center belt,lateral belt,nearside belt,distal belt and outside belt,hydrothermal alteration intensity of which decreases from inner to outside.The alteration types are mainly albitization,illitization,carbonation and apatization.The uranium content is positive correlated to the contents of Na2 O,FeO,CaO,MnO,P2O5,which could be resulted from the albitization that superimposed on quartz and K-feldspar.MgO.And Fe2O3 contents reduce gradually from inner to outer alteration zones,which were probably related to chloritization of biotite and plagioclase on both sides of the alteration zones.The trace elements (such as Sr,Pb,Zn,Mo,W,Bi,Sb,Ta,Zr,and Hf) are positively correlated to U.The U content in the strong alteration zone is much bigger than that in weak alteration zone,indicating that the ore-forming fluid and material were derived from the depth but not from wall rocks.In addition,the total amount of REEs,δEu value,and positive correlation to U content in the alteration zones suggest deep source of the ore-forming fluids in origin.关键词
