摘要
深冲矿区位于南岭成矿带苗儿山铀矿富集区。本文从构造地球化学找矿角度出发,在研究矿区构造地质背景、断裂构造地质特征及控矿特征的基础上,运用数学地质方法对矿区成矿断裂构造地球化学特征进行分析。初步认为区内有利铀矿赋存的构造组合形式是多方向构造圈围或多构造夹持区;成矿断裂构造带地表或浅部具有Hg、Bi、Sb、Mo前缘元素异常特征;放射性地球化学场具有伽玛能谱铀晕值高、规模大、浓积中心明显,并具有铀能谱异常点、带产出和U-Th-210Po元素组合异常发育等特征。根据上述成矿断裂构造地球化学异常特征圈出区内有利找矿靶区,经钻孔验证取得了较好的找矿效果。
Shenchong deposit in Miaoershan mountain district which is enrichment uranium of Nanling mineralization belt.This paper is to analyze the tectoinc-geochemical characteristics of metallogentic fault by the mathematical geology method from tectonic-geochemical exploration which is based on studying the tectonic-geological background,geological characteristics and ore-controlling features of fracture structure in this area.And preliminary considers that the combined structure type of promising occurrence of uranium is muilt-direction structure bound-up and muilt-fault structure pinched zone.The ground surface or upper of metallogentic fault that has anomaly of Hg, Bi, Sb, Mo as the front elements. The gammaray spectrum uranium anomaly halo that has high in value,large in scale and concentrated product center clearly and characteristics of gamma-ray spectrum anomalous spots and zones and U-Th-210 Po elements combined anomalous characteristics.The drilling checking test has received a good prospecting result by delineated favorable exploration targets which is according to tectoinc-geochemical anomaly characteristics of metallogentic fault.
