我国固体矿产资源储量分类与CRIRSCO分类对比——以加拿大Lac Otelnuk铁矿为例

Contrastive Study on China's Solid Mineral Resources Reserves Classification and CRIRSCO Classification——Taking Lac Otelnuk Iron Ore Deposit as an Example

以加拿大Lac Otelnuk铁矿矿床为例,分别采用中国传统的地质块段法,依据中国资源储量分类标准,和采用构建矿床地质模型,按CRIRSCO标准对该矿床进行了资源量估算,对比分析了两种估算方法的不同结论,探讨了我国固体矿产资源储量分类与CRIRSCO模板分类的差异。

Taking Lac Otelnuk Iron Ore Deposit as an example,according to classification standard of resources reserves in China,the traditional Chinese geological block method and geologic model establishment of deposit are used to estimate the deposit resources based on CRIRSCO standard.The paper compares and analyzes the different conclusions of the two estimation methods,and discusses the difference between China’s solid mineral resources reserves classification and CRIRSCO classification.
