一、前言研究深部地质构造特征与矿床生成和空间分布的相互关系,是研究区域成矿规律、开展成矿预测工作的一个新课题,自六十年代中期以来在国内外日愈受到重视。目前的基本作法是,运用区域重力测量、地震测深、大地电磁测深、天然地震转换波、航空磁测和超深钻探等手段,查明地壳各层的厚度以及康氏面、莫氏面、M_1界面(上地幔内部界面) I. INTRODUCTION The study of the relationship between deep geological tectonics and mineralization and spatial distribution is a new topic to study the metallogenic regularity and carry out metallogenetic prediction in the area. Since the mid-1960s, it has been paid more and more attention at home and abroad. At present, the basic practice is to find out the thickness of the crust by using the methods of regional gravimetry, seismic sounding, magnetotelluric sounding, natural seismic conversion wave, aeromagnetic magnetism survey and ultra-deep drilling, , M_1 interface (upper mantle inner interface)
