辽西─冀北地区铀成矿遥感地质信息的研究

本文从辽西—冀北铀矿床成矿地质环境、时空分布及矿床特征出发，在以遥感信息为主，综合地质、物化探、水文等资料的全区性联幅应用开发、复合成图、综合分析以及重点地区的野外详细调查的基础上，运用切合全区地壳运动的演化理论，揭示了区内地壳演化及其结果的构造格局、区域地质背景、铀成矿条件和时空分布规律，建立了不同岩区环弧形构造解译标志，并阐述了其地质成因。解译了火山机构、小型封闭沉积盆地和铀矿密切相关的岩浆岩体，着重解译了控矿构造和矿化蚀变带的产状、类型，强调解译了卫片图像“热晕点”，并讨论了其地质意义和铀矿的关系，最后确定了遥感地质找矿模式和综合预测模型。

Study on the Remote Sensing Geological Information of Uranium Mineralization in Western Liaoning and Northern Hebei

Based on the whole areal geological map joint application ard exploitation,composite forming map,generalization analysis and field examination in detail of key region that mainly deperd on remote sensing information and generalize the data of geology,geoppysical and chemical prospecting, and geohydrology, this paper reveals the structure framework, regional geological background,uranium metallogenic condition and space time .distribution rule of crustal evolution and its result,and set up the interpretation marks of arc- shaped structure in different of rock area and discusses its geological genesis. The author also interprets volcanic apparatus,srnall type closed sedimentary basin, magmatic rock bodys which relate closely to uranium deposit lore control structure and occurrence and type of mineralization alteration envelope. The thermal halo point of satellite image is emphatically interpreted and its geological meaning and its relation to uranium deposit is discussed. Remote sensing geological prospecting ore model and synthetic provision model is determined lastly.
