摘　　要：化探找矿正逐步从定性走向定量,在前人研究的基础上,提出了适用于老矿区深部探矿工程少、埋藏较深的矿产资源量估算的计算方法——面金属量积分法和三维地质体块段法。以江西城门山矿区为例,以区内主要含Mo地质体为计算对象,依据各中段面Mo的成晕地球化学信息,结合城门山三维地质—地球化学实体模型,对矿区浅部(第一空间0^-500 m)和深部(第二空间-500^-1 000 m)Mo资源量进行了估算。从计算结果来看,2种方法对浅部资源量估算结果都与已知储量相吻合,深部预测以三维地质体块段法更理想。Geochemical exploration has been gradually transformed from qualification into quantification.Based on previous research results,the authors put forward two methods,i.e.,areal productivity integration and 3D geological blocks,to calculate the resources of concealed ore bodies in old diggings,which are characterized by lack of exploration engineering and deep burial.With the prediction of Mo resources in the Chengmenshan ore deposit as an example and the geological body rich in Mo as the calculation object,and according to the Mo geochemical halo formation in different cross-sections in combination with the characteristics of 3D ore deposit,the authors estimated Mo resources at the shallow part（the first space 0～-500 m） and the depth（the second space-500 m～-1 000 m） of the mining area.The calculation results show that the resources estimated by these two methods at the shallow part are consistent with actual estimations,but the 3D geological blocks method is better in predicting the resources at the depth.
