我国固体矿产物探现状与展望

文章在分析了固体矿产形势之后指出我国普查找矿任务很大,而历年我国物探找矿效果也较好。我国物探技术水平与国外比虽有差距,但有自己特色,一些方面达到了国际水平。为适应找隐伏矿、深部盲矿、难识别矿及新类型矿的需要,要把物探推进到新的发展阶段,即第二代物探阶段。第二代物探是使用先进水平的方法技术,运用目标物地质-地球物理模型指导整个工作的思路,系统地开展好物探工作,以解决更多更复杂的地质问题。文章指出第二代物探的五个方面要求及特点。为了实现第二代固体矿产物探的目标,方法技术要有较大进步和有突破性进展。文章提出了十二个应开展的研究课题,涉及方法的改进和提高,新原理、新方法、新参数的研究;综合方法运用的研究等三大类课题。

THE PRESENT SITUATION AND PROSPECTS OFGEOPHYSICAL PROSPECTING FOR SOLIDORE RESOURCES IN CHINA

Based on an analysis of the present situation of solid ore resources, thispaper points out that reconnaissance and ore prospecting task is very heavyin China and that geophysical prospecting has proved to be quite effective inChina in these years. The geophysical technique of China, although somewhatlower in level compared with that abroad, shows its own distinctive featuresand has already reached international level in some aspects.In order to meet the demand of prospecting for concealed deposits, deepblind deposits, deposits not easy to be recognized and deposits of new types,it is necessary to carry forward geophysical prospecting to a new stage, i. e.geophysical prospecting of the second generation. During this stage, advancedmethods and techniques are to be used and objective geologic-geophysicalmodels will be applied to guide train of thought of the whole work. In thisway, geophysical prospecting will be carried out systematically and morecomplicated geological problem call be solved. The paper deals with five aspe-cts of requirements for geophysical prospecting of the second generation andits characteristics.The attainment of the aim of the second-generation geophysical prospe-cting for solid ore resources requires greater progress and breakthrough advan-ce in methods and techniques. The paper suggests twelve topics for futureresearch, which cover three classes: the improvement of the available methods;the study of new prinoiples, methods and parameters;the application of inte-grated methods.
