新疆鄯善县恰特卡尔地区基性-超基性岩型铜镍找矿模型及矿产预测

Metallogenic Model and Mineral Prediction of Basic-Ultrabasic Rock Type Copper-Nickel in Chattkar Area,Shanshan County,Xinjiang

在野外地质调查基础上,对研究区地质、航磁、重力、化探信息进行分析研究,结合典型成矿岩体岩石学、岩相学、岩石化学及同位素研究成果,对岩体、构造、航磁、重力、化探及矿化标志信息进行提取,建立研究区铜镍找矿模型。采用综合信息地质单元法、特征分析法、地质体积法进行预测区的圈定、优选及资源量定量预测,圈定A类找矿靶区11处,B类找矿靶区13处,C类找矿靶区15处,估算镍资源量358×104t,显示了研究区铜镍矿巨大的找矿前景。

On the basis of field geological survey, we analyzed and studied the geological, aeromagnetic, gravity, and geochemical information of the research area, combined with the research results of typical metallogenic rock body of petrology,petxography,petrochemistry and isotope,and extracted information about the rock,stxucture, aeromagnetic, gravity, geochemical and mineralization marks, to establish the Copper-nickel prospecting model in the research area. We adopted Integrated information geological unit method, characteristic analysis and Geologic volumetric method for the delineation, optimization and quantitative prediction of resources of the prediction area, delineated 11 ore prospect- ing target areas of class A, 13 ore prospecting target areas of class B,and 15 ore prospecting target areas of class C,and estimated the resource of 3.58 million tons,shows the great prospects of copper - nickel ore prospecting in the research area.
