摘要
野外找矿工作中,地质人员最揪心的就是等待样品化验成果数据。笔者团队在大路锰矿工作中,通过X荧光仪对该区锰矿钻探岩心进行快速测量,发现该方法的测量数据对锰矿的富集地层判断精度高,对矿体的判读准确度也极高,而且通过仪器精准标定后,其测量结果与室内化验室数据进行对比,接近程度很高,尤其是对于品位大于5%以上的锰矿(化)层,测量结果与化验室结果误差一般都在5%以内。本次研究成果对野外矿体确认及岩心采样段、采样长度的决定具有客观的、高效的指导意义。
In the field prospecting work,the most important thing for geologists is to wait for the data of sample test results.The test pe?riod is generally relatively long.In the exploration work of the Dalu manganese deposit,the author's group quickly surveyed the drilling cores of the manganese deposit by X?ray fluorescence instrument.It is found that the measurement data of this method have high accura?cy in judging the enriched strata of manganese ore and the interpretation accuracy of orebody.Moreover,the instrument is precise.After calibration,the results of measurement are compared with those of laboratory data.The degree of approximation is very high.Especially for manganese ore(chemical)layer whose grade is more than 5%,the error between the results of measurement and laboratory results is generally less than 7%.It has objective and efficient guiding significance for orebody confirmation,core sampling section and sam?pling length determination in the field.
