区域资源定量评价中面金属量法的应用——以东天山为例

Application of areal productivity to quantification of regional resources:A case study of East Tianshan Mountains

地球化学方法被普遍应用于矿产资源评价,但多数方法都只是基于地球化学数据本身而进行的,较少考虑除成矿物质来源之外的诸如构造、地层等地质环境的影响。文章运用面金属量法,在充分研究地质因素的基础上,确定了预测单元及地球化学背景值,在一定程度上屏蔽了虚假资源量,对东天山地区铜的资源量进行了定量评价。预测认为,东天山地区铜的资源潜力巨大。

Geochemical methods have been commonly used in mineral resource assessment. Most of them, however, were based merely on geochemical data, with less attention paid to geological factors such as tectonics and strata. This paper estimated the copper potential reserves in the East Tianshan Mountains by using the areal productivity method. The authors proposed prediction cells and geochemical background to calculate copper potential reserves. It is shown that the potential copper resource in the East Tianshan Mountains is abundant.
