放射性－遥感技术在鞍本地区铀成矿环境分析及远景预测中的应用

作者运用放射性－遥感（即光－能谱）集成技术对鞍本地区区域地质构造格架及铀成矿环境进行了研究，提出辽阳晚太古代花岗质穹窿构造和两条古深大断裂对该区构造格架、岩浆活动及铀成矿起重要的控制作用；在花岗质岩石的物源和成因方面得出了某些新的认识，并据此总结出铀成矿机理“三要点”，预测了铀成矿远景区，指出弓长岭南部与连山关花岗岩体西部之间是最有利的成矿远景区。同时，运用该技术对燕山期花岗岩岩体进行了等级体制填图的探索，结果表明，这是一种快速、准确、高效的新方法。

APPLICATION OF RADIOACTIVITY-REMOTE SENSING TECHNIQUES TO URANIUM METALLOGENIC ENVIRONMENT ANALYSES AND PROSPECTIVE PROGNOSIS IN ANSHAN-BENXI AREA,LIAONING PROVINCE

Using radioactivity-remote sensing(i. e., light-energy spectrum) integrated techniques,the authors study the regional geologic structural frame and uranium metallogenic environment, propose that the Late-Archaean Liaoyang granitic dome-shaped structure and two ancient deep-seated large faults have important control to the regional structural frame, magmatic activity and uranium mineralization. Some new ideas about material resource and evolution of granitic rocks are obtained, .and three important points about uranium metallogenetic mechanism are also summarized.At the same time, the uranium prospective areas are predicted. Finally, the authors explore the mapping method of granitic rock grade system bymeans of applying the technique. It is proved to be a quick, accurate and high efficient newmethod.
