摘　　要：安妥岭钼矿地质勘探中,17个已获得岩芯样品品位的钻孔组成了3个(自西向东依次为10号、14号和18号)比较完整的勘探线剖面,对它们进行综合地质解译之后获得3个勘探线剖面内矿体的边界。将位于东西两侧的18号和10号勘探线内的矿体边界分别向东和向西平移勘探线剖面间距的一半(50m),同时矿体面积减半,分别作为矿体的东部和西部边界。以上述五个剖面内的矿体边界形态为基础,运用Micromine建立了钼矿体的线框模型,使用距离加权反比法建立了安妥岭钼矿体的矿块模型。初步探讨了矿石品位在10号、14号和18号勘探线剖面内的空间分布特征,并对矿体线框模型在水平、南北和东西方向上进行了一系列的剖切,探讨了矿体形态在三维空间内的变化特征,也为进一步的钻探设计提供借鉴。In geologic exploration at the Antuoling molybdenum deposit,three relatively integrated geologic sections composed of 17 drill holes with acquired Mo grades,No.10,No. 14 and No 18 from west to east,were interpreted,and ore body boundaries were identified in these sections. The ore body boundaries in No. 10 section and No. 18 section were shifted by 50m （half distance between sections） toward west and east,respectively. And the area of the ore body was reduced to a half to serve as its eastern and western boundaries. On the basis of the five ore body boundaries above,the linear-frame model of the Mo ore body was constructed by Micromine and the block model was established using inverse distance weighting method （IDW）. Spatial distribution features of Mo grade were described for sections No 10,No 14 and No18,and ore body shape features were recognized based on a series of perspective observations in horizontal,north-south and east-west directions. The result provides a reference for borehole design in the further exploration.
