摘要: 本文根据我国金属资源勘查的现状,提出了地球物理在隐伏矿勘查阶断的发展对策.在近期,着眼于方法综合和技术配套,使总体找矿能力达到300—500 m深度,满足当前找矿的需要.同时依靠科技进步加速基础研究,着眼于地球物理大三维全空间的勘查能力,重点发展高分辨率大深度勘查的高新方法,作为改造传统推动金属资源勘查的发展动力.力争在十年左右的时间里,总体勘查能力达到1.5—2 km.笔者认为,解决金属资源问题,最终取决于对金属资源与地壳上地幔深部结构(包括良导层)关系的认识.据此,建议在大型矿山进行深部矿根构造的MT调查,可能会有重要的突破.

Abstract: A strategic overview is presented on the adaptation of geophysics to the present situation of geological exploration in which decp-burried deposits are principally concerned in China. To meet this demand it is imperative that the entire exploration capacity reach the depth of 300-500 meters with integrated applications of various geophysical methods and techniques. Meanwhile, based on the improvement of three dimensional whole-space geophysical exploration capacity, high-advanced techniques with good resolution and great exploration depth should be primarily developed in order to renew the conventional techniques and stimulate the development of metallic resource exploration. The overall exploration capacity is thus expected to be up to 1.5-2 km by the advent of the 21st century.The authors believe that whether the problems involved in metallic resource exploration can be solved or not will eventually be determined by the correct recognization of the relationship between metallic resources and the deep structure of the crust and the uppcr-mantal, so MT surveys should be carried out to investigate the roots of great mines.
