矿床地质经济模型法在东天山铜镍矿预测中的应用

Application of geo-economic model: A case study of copper-nickel sulfide deposits in eastern Tianshan Mountains, China

以中国铜镍硫化物矿床成矿规律研究现状和2005年全国储量平衡表为依据,在分析总结国内外品位-吨位模型研究的基础上,建立了中国铜镍硫化物矿床的矿床地质经济模型,主要包括描述性模型和品位-吨位模型。并以新疆东天山为例,采用矿床地质经济模型法对铜镍硫化物矿床的资源潜力进行评价,共圈定29个矿田级远景区,估算铜资源量453×104t,镍资源量448×104t,表明东天山地区该类型矿床资源潜力较大。

On the basis of ore-forming discipline and regulation of Cu-Ni sulfide deposit and national reserves data to the end of 2005 ,by analyzing and summarizing the studies about models of grade-tonnage home and abroad, descriptive and grade-tonnage models of Cu-Ni sulfide deposit has been founded in China. By applying it in the eastern Tianshan, the mineral resources potential of Cu-Ni sulfide deposit has been assessed, this conclusion has been drawn that 29 mine-field-grade prospective areas have been delineated and Cu resource of 4.53 Mt and Ni resource of 4.48 Mt have been estimated. This indicates that eastern Tianshan area has large potential of prospecting for this type of deposits.
