摘　　要：河南嵩县土地庙沟铅锌矿受地层和区域性深大断裂的次级顺层断裂双重控制(受北西向栾川-维摩寺深大断裂影响),矿体多呈似层状、透镜状和脉状产出,分布于碎屑岩与碳酸盐岩之间的层间破碎带内和碳酸盐岩中,含矿层位稳定。区内煤窑沟岩组地层中发现了K1、K2、K3、K4、K5共五条主要铅锌银多金属矿化层,铅锌品位0.62%～11.15%,银品位48.4×10-6～677.1×10-6。通过对矿区地质、矿体的矿物组合、结构构造、矿化和蚀变等特征分析,阐述了土地庙沟铅锌矿地质特征和该区的找矿方向。The Tudimiaogou Pb-Zn deposit in Songxian county,Henan province,is controlled by strata and subsidinary fractures of the regional deep fault（NW direction of Luanchuan-Weimosi deep fault）.The orebody mainly occurs in layered,lens and vein shape in the fracture zone between the clastic rock and carbonate.The ore-bearing horizon is stable.Five major lead-zinc polymetallic mineralized layers,named K1,K2,K3,K4,K5,were found in the Meiyaogou formation.The Pb-Zn ore grade is 0.62% - 11.15%,and Ag grade is 48.4 × 10^-6 - 677.1 × 10^-6.Based on the analysis of the geology,mineral assemblage,structure,mineralization and alteration characteristics,the author propose the prospecting direction for this area.
