摘要
照金-焦坪一带位于鄂尔多斯盆地南缘东部,处于渭北隆起与陕北斜坡过渡区域,周边分布有店头铀矿床。笔者通过典型矿床分析,结合成矿地质条件、航空放射性异常查证结果,总结砂岩型铀矿找矿标志,建立数学-物理找矿模型,并用俄罗斯半定量成矿预测技术对该研究区进行了成矿预测,新划定铀成矿远景区2片,推进了该地区铀矿资源勘查。
The Zhaojin-Jiaoping area is located in the eastern part of the southern margin of the Ordos Basin,in the transitional region between Weibei uplift and Northern Shanxi slope,and the Diantou uranium deposit is distributed around it. Based on the analysis of typical deposits,combined with the ore-forming geological conditions and the verification results of airborne radioactive anomalies,the author has summarized the prospecting criteria of sandstone-type uranium deposits,and established a mathematical-physical prospecting model,and used Russian semi-quantitative metallogenic prognosis technology to carry out metallogenic prognosis in this area,two newly defined uranium metallogenic prospective areas,which promotes the exploration of uranium resources in this area.
