东南极格罗夫山地区铷含量初步调查及手持矿石分析仪的可行性研究

本文对东南极格罗夫山地区出露的基岩样品进行实验室地球化学分析,结果显示出该地区明显的铷元素富集。所测试的123个样品主要为花岗岩、闪长岩、花岗片麻岩、片麻岩等,其中15个样品的铷含量达到0.04%,2个样品的铷含量达到0.1%以上。同时,利用手持快速矿石分析仪（NITON XL3t-500S GOLDD）对该地区213件岩石样品以及92件粉末样品进行测试,并将测试结果与实验室分析结果进行对比分析。分析对比发现,虽然手持快速矿石分析仪相对实验室测试存在一定误差,但是两种测试方法的铷含量随样品表现出一致的变化趋势,且粉末样品相对岩石样品误差明显偏小。...

This work conducted laboratory geochemical analysis on the exposed bedrock in the Grove Mountain area of East Antarctica,and the result shows that Rubidium（ Rb） is rich in this area. The tested 123 samples are mainly granite,diorite,granitic gneiss and gneiss,of which 15 samples contain about 0. 04% Rb and two samples contain Rb content up to 0. 1%. In addition,the portable mineral analyzer No. NITON XL3 t-500 s Gold was applied to test 213 rock samples and 93 powder samples,and the test results were compared with the laboratory results. The results show that there is some error for the portable mineral analyzer relative to laboratory geochemical analysis. However,the variation trends of Rb content of the above two methods are consistent,and the error from powder analysis is obviously smaller than that from rock sample analysis.
