摘要
大青山地区燕山晚期火山活动强烈,形成中心式火山塌陷盆地,从盆地中心向外依次发育多种类型的铀矿化.对该区铀成矿地质条件进行分析,认为火山塌陷盆地的内外接触带是铀矿成矿的最有利部位,具有较大的找矿潜力,据此提出该区铀矿找矿方向.
The Daqingshan area in Liaoning Province experienced intense volcanic activities during late Yanshanian, forming the volcanic collapse basin of central style. Various types of uranium mineralization are developed from the center to outside of the basin. With analysis on the geologic conditions for the metallogenesis of uranium deposits, it is recognized that the endocontact and exocontact of the volcanic collapse basin are favorable positions for uranium metallogenesis, with great potential. Based on this, the prospecting direction for uranium deposits in the area is pointed out.
