全国整装勘查区成矿系统研究与矿产勘查新进展

Metallogenic System of Integrated Exploration Area and New Exploration Progress

全国先后共设置了141个整装勘查区,分布在26个重点成矿区带,位于古亚洲、滨太平洋、特提斯三大成矿域。整装勘查区成矿条件优越,矿产资源丰富,矿床类型复杂多样。运用成矿系统理论,对全国典型整装勘查区开展了研究与梳理,按构造动力体制划分出3类成矿系统,按照成矿机制划分出4类成矿系统,并划分(厘定)出24个成矿系统亚系统。根据上述成矿系统研究成果,重新划分出14个成矿系列、34个矿床式,建立了典型矿床的结构模型,在此基础上构建了15个成矿系统空间结构模型。归纳总结整装勘查区成矿系统,建立成矿系统空间结构模型,运用缺位找矿思维,调整整装勘查区区域矿产勘查工作部署,开展新矿种、新类型、新区域、新层位勘查找矿,取得了重要进展与成果,丰富了成矿系统和勘查区找矿预测理论。

The integrated exploration areas(IEA)are located in the paleo-Asian Ocean,circum Pacific Ocean,and Tethys melallogenic domain,with favorbale metallogenic conditions,rich in mineral resources,and diversified types of deposits.Currently,a total of 141 IEAs are arranged over 26 main metallogenic belts in China.Based on the theory of metallogenic system,we carried out a preliminary research on the typical IEAs,and divided them into three and four types of metallogenic systems according to tectonic dynamic mechanism and metallogenic mechanism,respectively,and further divided them into 24 subsystems.In addition,we reclassified 14 metallogenic series and 34 ore deposit types,established the structural model of typical deposits,and on this basis,15 spatial structural models of metallogenic systems were established.On this basis,using the idea of vacancy prospecting,we adjusted the approach of mineral exploration and made breakthroughs in mineral exploration of new types,new areas,and new space,which promoted the development of the theories of metallogenic system and prospecting prognosis in exploration areas.
