| 摘 要： | 在相山铀矿田开展了分量化探方法稳定性、异常重现性及有效性研究。结果表明,分量分析方法稳定性较高,同一样品多次测试结果之间的符合度及不同时间(批次)测试结果的一致性均较好。石里坑地区的重复性测量结果显示,两次测量的分量铀平均含量相近、地球化学波动特征相似、局部分布形态和部分高值区的强度有所差异,但高值区和低值区的展布形态、空间位置吻合较好,说明分量化探的异常重现性较好。云际工作区的分量化探测量结果表明,分量铀高值区(带)与已知矿体的空间对应关系较佳,可有效地指示深部隐伏铀矿体,反映了分量化探在相山盆地铀矿勘查中的有效性及适用性。

| Abstract: | The study on stability, anomaly reproducibility and validity of the partial extraction geochemical prospecting method was carried out in Xiangshan uranium ore field. In Shilikeng area, the repetitive and the original measurement results is similar in the average contents of partial extracted uranium and the geochemical fluctuation characteristics, and of good agreement in the overall distribution pattern and position of high-value areas and low-value areas although there is little difference in local distribution pattern and the intensity of some high-value, which indicates that the anomaly reproducibility of the partial extraction geochemical prospecting method is good. In Yunji working area, the results of the partial extraction geochemical prospecting indicate that the high-value zones of partial extracted uranium have a better spatial correlation with the known ore bodies, which can effectively indicate the deep concealed uranium ore bodies. The results showed that the partial extraction method has high stability, the conformity between the multiple test results of the same sample and the consistency of the test results at different time(batch) are good, reflecting the validity and applicability of the partial extraction geochemical prospecting method in Xiangshan basin. |
