摘要
本文根据 1996年国外发表的勘查地球物理文献 ,概要列举了物探方法发展的新前沿。在矿产勘查方面介绍了金属矿预测和普查工作的新进展以及金伯利岩、滑石矿床的找矿方法和实例。在环境勘察方面 ,回顾了电法在水质调查中的应用 ,介绍了物探方法在城市垃圾场调查、煤矿闭坑善后工作、城市人工物理场环境效应调查中的应用以及滑坡和洞穴调查中新采用的方法。在区域和深部地球物理调查方面 ,概述了西方国家近年来实施的矿产勘查开创计划、大规模的电导率结构研究和南极磁异常图的编制。在新技术新方法方面 ,介绍了新的航空电磁系统———FLAIRTEM、电 (磁 )法中非接触数据采集技术、谱激发极化法在环境调查中的应用。
Based on geophysical literature published abroad in 1996,this paper first describes briefly the new frontiers in the development of geophysical techniques.In the field of mineral exploration,new advances in prognosis and prospecting for ore deposits,exploration methods,and case histories of kimberite and talc deposits are recounted.In the field of environmental investigation,the application of electrical methods to water quality survey is reviewed,and the utilization of geophysical techniques in urban dump survey,the site investigation of abandoned collieries,and the study of environmental effects of urban artificial physical fields as well as the newly adopted methods in landslide and cavity detection are reported.In the field of regional and deep geophysical investigations,the Mineral Exploration Initiative carried out recently in some western countries,the study of large-scale electrical conductivity structure,and the compilation of Antarctic magnetic maps are outlined.In the field of new exploration methods,description is given in such aspects as new airborne EM system——FLAIRTEM,non contact data acquisition techniques in electrical(EM) explorations,measurements of spectral induced polarization for environmental application,new regional exploration methods for detecting hydrocarbon alteration plumes,and sea gravimeter.
