英文摘要：

Variogram is the core and basic tool of geostatistics and can describe spatial structures and random changes of regional variables. Variogram analysis is the foundation of many other geostatistic calculations. Based on geostatistics theory and variation functions, we built the Pg, Zn grade variation model for the Baiyang-Chuanxindong ore and Duimenshan-Awei ore. Among them, the continuity of two main ore-forming elements along strike is the best, followed by the dip direction, and the worst along the normal to the bedding. The best exploration for network degree different ore block is determined. The proposed Baiyang- Chuanxindong ore section prospecting network degree is 50 m× 30 m and the exploration network degree can be 80 m × 75 m for the Duimenshan-Awei ore due to its little variability.
