常规次生晕法在闽东南火山岩区找矿成效及意义

Prospecting effectiveness and significance of application of conventional secondary halo method in volcanic rock area of Southeast Fujian Province

在表生作用下,成矿元素及伴生元素主要以化学分散晕形式存在于土壤中,对土壤地球化学测量十分有利。本文以近年来在闽东南火山岩地区新发现矿区为例,重点介绍化探次生晕法在该矿区找矿的方法及成果,由矿床个体研究扩展到区域,旨在说明次生晕法在闽东南沿海火山岩区寻找隐伏金属矿床的有效性,对闽东南沿海火山岩区金属矿的找矿工作具有重要的启示意义。

Under the epigenetic effects, ore-forming elements and associated elements are mainly formed in the form of chemical dispersion halo, and exist in the soil, and so it is very important to the survey of soil geochemistry. We take a new ore district in the area of volcanic rocks in southeast of Fujian province which was found in resent years for example, mainly introduce the method and significance of applying routine secondary halo method to prospecting work in this area, and then extend to regional research. The successful locating of blind ore bodies by secondary geochemical halo method in this example suggests that the secondary halo anomaly method is effec- tive and can be employed in search for other metal mineral prospecting in southeast of Fujian.
