摘　　要：羊橺梁子铅锌矿体赋存于花岗岩体与志留系中上统(S_(2+3))大理岩、砂页岩接触带附近的大理岩中,矿化严格受岩性、构造、岩浆岩等联合控制,在岩性差异面矿化相对集中。矿体呈似层状产出,在走向、倾向上较连续稳定,与围岩产状近乎一致。矿床成因属矽卡岩型铅锌矿床,矿区下一步工作的重点区域为矿区的深部及东部区域。The Yangjianlangzi lead-zinc ore body occurs in the marble near the contact zone between the granite body and the Silurian Middle-Upper Series (S_(2+3)),sand and shale,and the mineralization is strictly controlled by lithology,structure,magmatic rock,etc.,and the mineralization is relatively concentrated on the lithological difference surface.The ore body is stratiform-like output,which is more continuous and stable in strike and tendency,and is almost consistent with the occurrence of the surrounding rock.The genesis of the deposit is a skarn-type lead-zinc deposit,and the key areas for the next work in the mining area are the deep and eastern regions of the mining area.
