摘要
诸广山岩体是南岭成矿带的多金属矿重要成矿岩体,鹿井矿田位于诸广山岩体中部,矿田内发现的矿床有10余处,是我国南方重要的铀资源地之一。该矿田铀成矿期次多,成矿地质背景复杂。结合实地勘察、当地的资料,对矿田内各矿床的成矿地质特征进行了研究分析,得出了岩体特征、岩体与矿体空间关系、成矿流体特征。初步判定鹿井铀矿田成矿地质体为燕山早期第三阶段花岗岩及燕山晚期侵入岩脉、小岩体,同时确定了成矿地质体与铀成矿的关系,进而指导找矿。
Zhuguangshan pluton is an important polymetallicmineralization rock body in Nanlingmineralization belt.Lujing Orefield, located in the middle of Zhuguangshan rock body, consists of more than 10 deposits and thus is one of the important uranium resources in South China. The uranium in the orefield was mineralized in a number of periods and the geological background for the mineralization is complex. Based on field investigation and local data, the authors have studied and analyzed the geological characteristics of mineralization in the deposits of the orefield and obtained the characteristics of rock body, the space relationship between rock body and ore body, and the fluid characteristics ofmineralization. The preliminary judgement is that the geological body of mineralization in Lujing Orefield is the tertiary granite of early Yanshanian and the intrusive dike and small rock body of late Yanshanian. Meanwhile, the relationship between the geological body of mineralization and the uranium mineralization is determined to guide future prospecting.
