贵州从江县舒家湾铀矿元素地球化学特征及其意义

Geochemical Characteristics of Elements and Its Significance in Uranium Mine Sujawan in Congjiang of Guizhou

舒家湾铀矿位于摩天岭花岗岩体北端,在岩体中部及外围具有较好的找矿前景。在开展贵州省从江县南加地区铀铜多金属矿整装勘查战略选区调查评价项目时,对矿区铀矿石和围岩中的常量、微量和稀土元素地球化学特征进行了探讨。结果表明:矿区内Rb、Cs、W、Pb、Sb、Th、Ta、Sr等高场强元素与铀的迁移、富集有明显关系;铀与稀土元素的来源具有同源性。

Shujiawan uranium mine is located in the north end of the ancient uranium producing granite pluton of Southern China. It has a good prospecting prospect in the deep and peripheral areas. The author carried out the uranium and copper polymetallic ore integrated exploration strategic area investigation and evaluation project in Nanja area of Congjiang County of Guizhou province. The paper studied in detail the geochemistry of major elements,including trace elements and ree of uranium ore and rock and intrinsic realtion to uranium mineralization.Results show that some high field intensity elements like Rb,Cs,W,Pb,Sb,Th,Ta,Sr. The migration and enrichment of uranium has obvious relationship. Uranium and rare earth elements have a high degree of homology.
