地电化学勘探法在厚层覆盖区的应用研究

地电化学勘探法是以水溶形式元素为基础的现代勘查技术。由于该方法具有远距离记录地质体的成分, 以及寻找深部隐伏矿体的功能, 因而受到地学界的青睐。本文简要叙述了地电化学的方法原理及技术;重点介绍在金和铜矿床上的试验成果;列举了在新疆厚覆盖区的找金进程中, 地电化学综合方法对迅速开拓矿田的范围和规模, 对扩大矿田储量和成矿预测所作的显著贡献;初步总结了综合信息提取的最经济有效的勘查程序。这些成果, 无疑对地电化学勘探法的推广应用和异常的推断解释将是有益的。

THE APPLICATION OF GEOELECTROCHEMICALEXPLORATION METHOD IN THICK OVERBURDEN AREAS

The geoelectrochemical exploration method is a modern prospecting techni-que based on elements in the form of water solution. As this method has thecapacity of recording composition of distant geologic bodies and searching forconcealed lorebodies at depth, it finds favor in geologists’eyes. This paperdescribes in brief the principle and technique of the geoelectrochemical explo-ration method, expounds experimental results of this method in gold andcopper deposits, enumerated in detail the outstanding contributions made byintegrated geoelctrochemical method in rapidly opening up the limits anddimensions of the orefield, expanding ore reserves and making ore prognosisduring the gold prospecting process in thick overburden areas of Xinjiang, andsummarizes preliminarily the most economical and effective explorationprocedure for extracting integrated information. These outcomes contributeundoubtedly to the popularization of geoelectrochemical exploration methodand the inference and interpretation of anomalies.
