摘要
本文阐述珠光岩体中晶质铀矿的物理化学特征、产出位置和共生组合。提出该岩体晶质铀矿复成因的证据。认为它主要是岩浆阶段结晶的,自变质与他变质作用也产生了一些晶质铀矿。并提出可能含复成因晶质铀矿岩体内的铀矿床比含单成因晶质铀矿岩体的铀矿床富而大。对今后应用晶质铀矿这个标型矿物的特征找矿将有所启发。
Described in this paper are the physico-chemical characteristics,occurrence, locality and paragenesis of uraninite in the Zhuguang mass.Evidence shows that the uraninite is of polygenesis. It crystallizedmainly at the magma stage, while a certain part of uraninite resultedfrom autometamorphism and all chemical metamorphism. Uranium depositsoccurring in polygenetic uraninite-bearing masses are likely to be hig-her in grade and larger in size than those found in monogeneticuraninite-bearing masses. It is of significance to use the typomorphiccharacteristics of uraninite in future prospecting.
