| 摘 要： | 铀钨矿床是一种新矿床类型。其主要矿物是白钨矿和沥青铀矿，它们既有共生，也有伴生。钨以白钨矿细脉、分散状微粒白钨矿和吸附状等形式产出。钨与铀的成矿过程可划分为六个阶段。矿岩时差较大。钨来源于已固结的花岗石，它是由地下热水或热卤水从已固结的花岗岩中浸取出来的。钨（铀）矿化是在低温条件下，在有利的构造岩性中沉淀富集而成的，不是岩浆热液矿床

| Abstract: | This uranium tungsten ore deposit is a new type of mineral deposits,the main minerals in which are scheelite and pitchblende.They are not only paragenetic but also associted each other.Tungsten occures as scheelite stringer,dispersion mierograined scheelite and absorbed ions.The metallogenetic process of the uranium and tungsten can be divided into six stages.The time difference between ores and granite is large (>40 Ma).The tungsten was derived from the consolidated granite and Leached was out from the consolidated granite by thermal groundwater or hot brine.The mineralization of tungsten (uranium) formed under the low temperature and precipitated concentrated in the favourable structures and lithological Conditions,and no neans it was a deposit of magmatic origin. |
