3701铀矿床物、化探资料评价参数的研究

根据物化探方法(伽玛、伽玛能谱、径迹、~(210)Po、铀量及Pb、Cu、Mn的光谱分析)的测量结果与已知铀矿床在地表水平投影的重叠面积的对比,通过统计和分析,推导出衡量上述方法找矿效果的评价指标,提出了在该地区以评价参数R为主全面衡量各种测量方法的有效性的看法。并对矿床外围未知地段的找矿远景进行了预测。

SOME RESEARCH ON DATA OF GEOPHYSICS AND GEOCHEMISTRY IN 3701 URANIUM DEPOSIT

According to the comparison of geophysical and geochemical survey results (e. g. total gamma-ray, gamma-ray spectrum, track-etch, ~(210)Po, uranium amount and the optical spectrum analysis of Pb, Cu, Mn) with the horizont 1 project overlay area of known blind ores, some index of evaluring those methods mentioned above is deduced, using statistical and analysis ways. The paper also gives a point of view of comprehensive evaluting different exploration methods, based on the discrimination parameter R in the local area. A prospect unknown area outside the deposit has been predicted.
