■产有前寒武纪砂岩型铀矿床的雨淋环境中,实施了一项试验性的地球化学找铀计划。他们把总铀含量填图与依据多变量统计参数(主成分分析)得到的数据,以及从地表区水系沉积物样中所得到的数据进行比较所获的数据作为原始地球化学数据的一个修正系数。如果仅依赖原始数据就能获得这种修正
■ A pilot geochemical prospecting program was implemented in the rainy environment with Precambrian sandstone-type uranium deposits. They used data obtained by comparing total uranium mapping with data obtained from multivariate statistical parameters (principal component analysis) and from data obtained from sediment samples from surface waters as a correction factor for the original geochemical data . If you rely only on the original data to get this correction
