云南保山——昌宁地区铀矿找矿前景浅析

地质、物化探铀矿综合区调成果表明，保山－昌宁地区富铀层（岩体）为中元古界、前奥陶系、印支期及燕山期花岗岩；各种方法圈定的异常、晕（片）相互重合较好的地段是新街－莽水间凸起中南段，特别是5071，5072矿点所处的新街岩体及其内外接触带；铀矿化显示热液成因特征。据此推断，东部新街岩体之内外接触带热液型铀矿化是今后找矿的目标。

Preliminary analysis on prospecting potential of uranium in Baoshan-Changning, Yunnan province

Results of comprehensive geologic, geophysical and geochemical uranium reconnaissance indicate that the uranium-rich strata(bodies)are Middle Proterozoic and Preordovician, Indosinian and Yanshanian granitic bodies. The area where anomalous haloes delineated by different prospecting methods are superimposed is the central-southern part of the Xinjie-Mangshui median uplift, especially the Xinjie massif and its endo-and exo-contact zone where uranium occurrences No.5071 and 5072 are located. Based on the above-mentioned it is inferred that the hydrothermal uranium mineraliation at the eastern endo-and exo-contact of the Xinjie massif is the prospecting target in the future.
