摘要
龙首山地区是以碱交代型为主的铀成矿带,新水井-火石岭地区处于龙首山成矿带中段。通过地面高精度磁测工作,并结合地质情况,对该地段马路沟断裂及岩体分布特征进行了研究。共推断断裂构造5条,圈定侵入岩体8片,其中东南部2片闪长岩主要发育于浅部,而其他地段岩体深部延伸较深,并大致查明了区内构造格架、岩体的发育特征,为本区铀矿勘查提供了找矿信息。
Longshoushan area is mainly uranium metallogenic belt with the alkali-metasomatism type and Xinshuijing-Huoshiling region is in the middle of the Longshoushan metallogenic belt.This paper studies the Malugou faults and the spatial distribution of the rock by high-precision magnetic survey on the ground with the combination of geological conditions.There are 5faults inferred and 8pieces of intrusive rocks,of which two diorites in southeast develop mainly in the shallow section and other sections extend deeply.The structural framework and developmental characteristics of rock are generally identified,which provides deep prospecting information of the uranium exploration.
