根据我队条件,化探资料应用手算方法处理还是必不可少的,其效果比较显著。青海省茶茶沟地球化学异常,是我队一九六九年开展区域化探时发现的,异常以铅、锌为主。在一九七五年福州召开区域化探座谈会的推动下,我队用图解趋势分析重新整理资料。一九七六年我队组成化探分队,根据图解趋势分析的成果,布置了2平方公里的面积检查评价异常。工作结果圈出了一个面积达0.7平方公里的铅异常,一个面积达0.3平方公里的铜异常,并发现了在石英斑岩中的铜矿点两处。一九七六年我队在夺巧壳金矿点上开展物化探评价工作。对于发现的化探异常,进行了手算判别分析、相似性判别分析和点群分析的异常工作研究,工作结果对金矿的分布及赋存状态提供了意见,并初步建立了划分含金矿脉和非矿岩脉的化探异常评价准则。
According to our team conditions, the use of manual methods of geochemical data processing is still essential, the effect is more significant. The tectonic anomaly of Cha Cha Gully in Qinghai Province was discovered by our team in carrying out regional geochemical exploration in 1969. The anomalies were mainly lead and zinc. Driven by the Forum on Geochemical Exploration held in Fuzhou in 1975, our team rearranged the data with graphical trend analysis. In 1976, our team formed a group of chemical exploration units. According to the results of the graphic trend analysis, an area inspection assessment of 2 square kilometers was arranged. The results of the work circled a lead anomaly with an area of 0.7 km 2, a copper anomaly of 0.3 km², and discovered two copper deposits in quartz porphyries. In 1976, our team took geophysical and geochemical evaluation work at Qiao Qiao Gold Mine. For the discovered geochemical anomalies, the authors made hand-judged discriminant analysis, similarity discriminant analysis and point-group analysis anomaly work. The results provided the opinions on the distribution and occurrence state of gold deposits, And non-ore dikes geochemical anomalous evaluation criteria.
