雪米斯坦火山岩带伊尼萨拉地区铀多金属找矿方向分析

Analysis on metallogen ic geological conditions of uranium ploymetallic deposit in Yinisala area of Xuemisitan volcanic belt

伊尼萨拉地区是雪米斯坦火山岩带上继白杨河铀-铍-钼矿床后,又一主要的铀多金属矿产调查区。在总结该区地质构造与矿化特征的基础上,重点分析了铀多金属矿成矿地质条件,明确了找矿方向。认为在东部中酸性岩体侵入地层部位寻找热液型铀-钼-铍矿,南部查干陶盖勒断层北侧中泥盆统中酸性火山岩中寻找热液型铀-金-铜矿具有良好的找矿前景。

Yinisala is an importa nt survey area of uranium ploymetallic minerals after Baiyanghe U-Be-Mo deposit. This article summarized the geological structures and mineralization characteristics,with focus on analyzing the uranium polymetallic metallogenic geological conditions and defining the ore-prospecting direction. It is believed that the strata intruded by intermediate-acid pluton in the east have good ore prospect for hydrothermal uranium, molybdenum, beryllium deposits, and in the south the intermediate-acid volcanic rock in middle Devonian lies in the north side of Chagantaogaile fault has good prospect for hydrothermal uranium, gold, copper deposits.
