摘要 

本文是广东地区一幅1:5万化探水系沉积物测量的结果。常规的取样密度为4-5点/km2,放稀测网是在常规样品中,每km2抽取一个样品。用同样的方法分析十四种元素并编图,对比两种测网的效果。较稀测网可能遗漏个别的单元素异常,但不会漏掉多元素异常。两种密度测网的单元素异常数量特征、空间分布及所提供的找矿信息相似。

Abstract

This paper is based on the result acquired in 1:50, 000 geochemical stream sediment survey performed in a map area of Guangdong province. The routine sampling has a density of 4-5 samples per kilometers, while for the network of less density, samples are extracted from routine orates at the density of one sample per kilometer. 14 elements have been analysed by the same technique with map compiled to compare the result of these two sorts of network. Although very few single elements might fail to be discovered, the network of less density would not leave mufti-element anomalies undetected. These two densities of network bear resemblence in such aspects as quantities and spatial distribution of individual-elements and ore-prospecting information they provide.
