摘要
中国金属矿地球物理勘查近年来取得了显著进展。随着主要矿种转为以铜多金属为主、内地找隐伏矿难度增大与找矿重点转移到西部中高山区，轻便电法技术、重磁立体填图技术、金属矿地震技术、瞬变电磁法与高维电法反演方法等勘查新方法、新技术得到了卓有成效的发展，研制了达到和接近国际先进水平的阵列ＭＴ仪、Ｈｃ９５手持磁力仪、国产航空磁力仪、地井测量系统等仪器设备。同时对超导磁力仪，天然场及大功率激电、压电法等技术，以及非线性反演、联合反演和基于ＧＩＳ综合解释等新理论、新方法进行了探索并已有可喜进展。
In China, metal ore geophysical exploration achieves remarkable achievement in recent years. Prospecting strategy is made mainly for buried copper polymetallic ore deposits and the exploration target is shifting towards western mountain regions. New techniques, portable electric surveying, 3D gravity and magnetic mapping, metal ore seismic, TEM techniques and 2D, 3D electric inversion, for instance, are well developed and put into exploration. Some equipment, including Array MT system, Hc 95 hand magnetometer, airborne magnetometer and ground well logging system are made and attain to the advanced world levels. Effective researches are also carried out in many new technical fields, such as superconductive magnetometer, natural source IP, high power IP, seismic electric effect, nonlinear optimization, joint inversion and integrated interpretation based on GIS, etc.
