摘要: 通过大量的野外槽探和钻探研究,结合显微镜分析,查明辽宁省黄沟铀矿田矿化围岩蚀变主要有:绿泥石化、水云母化、赤铁矿化、绢云母化、钾长石化、硫化物化和碳酸盐化.铀矿化形成典型蚀变矿物组合:绿泥石+石英;绿泥石+水云母+石英;绿泥石+钠黝帘石+石英;绿泥石+水云母+赤铁矿+石英.水云母化应早于铀成矿期,为铀成矿提供了较好的环境;绿泥石化和赤铁矿化为成矿期蚀变;富矿主要与赤铁矿化、绿泥石化、水云母化等密切相关,其中赤铁矿化与绿泥石化叠加在一起对铀矿化作用显著,且近矿围岩蚀变强度越大、种类越多、叠加越多,则铀矿化越富.

Abstract: Wall rock alteration of the Huanggou Mine includes chloritization, hydromicazation, hematitization, sericitization, Kfeldspar alteration, sulfurization and carbonation based on a large of researches combined with microscope analysis. The typical alteration mineral assemblages of the uranium mineralization are chlorite+quartz, chlorite+hydromica+quartz, chlorite+saussurite+quartz and chlorite+hydromica+hematite+quartz. The hydromicazation is earlier than the period of uranium mineralization, and provides a better environment for it. The chloritization and hematitization of the accompanying mineralization of alteration take place lately. Highgrade ore is related to the hematitization, chloritization and hydromicazation. Hematitization and chloritization play an important role in the uranium mineralization. Moreover, the higher intensity, the more type and times of the ore wall rock alteration, the richer uranium mineralization is.

Key words: Liaoning, uranium mineralization, wall rock alteration, combination of elements
