一、前言水系重砂测量是区调工作中常用找矿手段之一。对于重砂矿物含量的认识与处理方法为: (一)普遍认为水系重砂矿物含量高,异常区级别就高,找矿意义就大。反之则低则小。因而,普遍以水系重砂矿物含量级别与异常区级别相吻合或相当为特征。 (二)水系重砂矿物含量级别划分不统一。同种重砂矿物的含量,划成三、四、五个级别的均有。 (三)大多数单位用统计法求重砂矿物含量背景值,划分含量级别。少数单位用数据处理方法整理和解释区域水系重砂矿物含量资料。并谓为“它所带来的优越性与我们比较熟
I. Preface Water system heavy sand measurement is one of the commonly used prospecting methods in the area adjustment work. For heavy sand mineral content understanding and treatment methods are: (A) It is generally believed that heavy sand mineral content of the water system, the abnormal area level is high, prospecting significance. The other is low. Thus, it is generally characterized by the fact that the mineralized heavy mineral content of the water system coincides with or is quite characteristic of the level of the anomalous zone. (B) of the heavy sand mineral content level is not uniform. The same kind of heavy sand mineral content, divided into three, four, five levels are. (3) Most units use the statistical method to calculate the background value of sand mineral content and classify the content level. A few units used data processing methods to sort out and explain the data of heavy sand mineral content in regional water system. And that "it brings the superiority with us more familiar
