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。
Based on the mineralization geological environment, space-time distribution and ore deposit characteristics of the western Liaoning-Hebei uranium deposits, the paper mainly focuses on the remote sensing information, comprehensive application of the geology, geophysical and geochemical exploration, hydrology, Based on the detailed investigation of the field in the key areas and the evolution theory of the crustal movement in the whole area, the tectonic setting, regional geological background, uranium metallogenic conditions and temporal and spatial distribution of the crustal evolution and its result in the area are revealed. The interpretation sign of circular arc structures in different rock areas and their geological causes are described. Interpretation of volcanic bodies, small closed sedimentary basins and uranium deposits are closely related to magmatic rocks, focusing on the interpretation of the ore-controlling structures and mineralized alteration zone of the occurrence, type, highlight the interpretation of the satellite image “thermal halo point ”, And discussed its geological significance and the relationship between uranium deposits, and finally determine the remote sensing geological prospecting model and comprehensive prediction model.
