内蒙古新城子火山盆地铀成矿条件分析

摘要

Xinchengzi volcanic basin is located in the south of Zhalantun volcanic type uranium metallogenie prospecting belt.It is also part of Huanggangliang-ulanhot polymetallic metallogenic belt.The tectonic location,basement and uranium concentration,structural features,wall rock alteration and uranium mineralization characteristics in the cover were analyzed and was believed that volcanic basin is with good metallogenic potential.%内蒙古新城子火山盆地处于扎兰屯火山岩型铀矿成矿远景带南部,也是黄岗梁-乌兰浩特多金属成矿带的组成部分.笔者通过对盆地基底岩性、盖层火山作用及岩石铀含量、断裂活动与蚀变矿化等方面的调查研究,认为该火山盆地具有“杂盖多面、主断切壳、蚀变叠加及铀矿化显示”等特点,是寻找大型火山岩型铀矿床的有利远景盆地.
