如何运用地球化学探矿方法来检查评价异常,肯定异常的性质与地质意义?目前国内外采用的方法主要有两种。第一种是在异常地段布置山地工程,进行揭露。这种方法是检查评价异常的基本方法,但由于次生晕具有位移、沾污等特点,所发现的异常往往距矿体(或矿化地段)还有一段距离,或者形成一些与矿体(或矿化)无关的非矿异常。这样在工作开始阶段立即使用山地工程进行揭露(特别是浮土覆盖较厚的地区),往往得不到满意的结果;而且成本高,效率低,不符合多快好省的要
How to use the geochemical exploration method to check the evaluation of anomalies, affirmed the nature of the abnormal and geological significance? At present, there are two main methods used at home and abroad. The first is to arrange mountainous areas in anomalous locations for disclosure. This method is to check the basic method of evaluation of anomalies, but due to displacement and contamination of the secondary halo, the anomalies are often found some distance away from the ore body (or mineralized area) Or mineralization) has nothing to do with the non-mining abnormalities. As such, the use of mountain works immediately for disclosure at the beginning of work (especially in areas with thick soils) often results in unsatisfactory results. Moreover, it is costly, inefficient and not in line with
