运用土壤地球化学寻找深部矿体的原理及方法

深部找矿已成为我国矿产勘查的主方向，难度很大，需要有效的方法技术，而本文则主要论证了运用传统的土壤地球化学寻找深部矿体的可行性及有效性。笔者对深部矿体中的矿石元素在地下深处的垂向运移及在汇水盆地内分散形成土壤地球化学晕的过程进行了半定量分析，通过计算和分析认为：运用土壤地球化学寻找深部矿体仍是有效的。最后，对运用土壤地...

Principle and Methods to Search for Ore Bodies at Depth Using Soil Geochemistry

Abstract:Orebody prospecting toward the deep subsurface has become the primary direction of present mineral resource exploration in our country.It is very difficult and requires effective methods and techniques.This paper deals with the feasibility and effectiveness of applying the traditional soil geochemistry survey to prospecting of ore bodies at depth.We make a semi-quantitative analysis of the vertical migration of elements from ore bodies at depthand downstream dilution of point source geochemical concentration.The results show that application of soil survey to prospecting deep orebodies remains an effective method currently.Finally,we present the key points for using soil survey to search for deep ore bodies in practice and the latest progresses in this field and suggest that successful application of soil survey in prospecting deep orebodies depends on the systematic,fine and scientific methods and technology.
