摘要
研究区位于我国重要的铀成矿带即青龙—兴城铀矿成矿带的西端。建昌中生代盆地南缘—干沟EW向火山断陷盆地内。地层表现为一老一新的“地台二元结构”特征;受多期构造运动的影响,区域地层产生了强烈的变质和混合岩化作用。这些因素为区域铀元素的活化、迁移、富集成矿提供了有利条件。研究采用经验模型法,在成矿理论的指导下,提取成矿信息,对各种成矿信息进行综合分析,开展矿产资源预测工作,确定找矿靶区。
The study area is located at the western end of Qinglong-Xingcheng uranium metallogenic belt,an important uranium metallogenic belt in China.It is the southern margin of Jianchang Mesozoic basin-Gangou EW-trending volcanic fault basin.The strata are characterized by an old and new“platform dualistic structure”.Under the influence of multi-stage tectonic movement,the regional strata have produced strong metamorphism and migmatization.These provide favorable conditions for the activation,migration and enrichment of uranium in the region.In this paper,under the guidance of metallogenic theory,the empirical model method is used to extract metallogenic information,conduct comprehensive analysis of various metallogenic information.We are also carrying out mineral resources prediction and determine prospecting targets.
