摘要
西普铅锌矿位于川滇黔铅锌成矿区的普格-会东成矿带的北段,通过矿床地质特征研究,认为区内奥陶系中统大箐组顶部白云质灰岩为矿区赋矿地层,矿体似层状,受黑水河背斜东翼层间裂隙群控制。认为其控矿因素为地层-岩性(相)-构造,为典型的沉积改造型矿床,在大箐组沉积过程中铅锌初始富集形成矿源层,经后期热液改造富集成矿。这一认识为下一步勘查找矿工作有重要意义。
The Xipu Pb-Zn deposit is located in the north of the Puge-Huidong metallogenic belt. Dolomitic limestone the upper part of the Meddle Ordovician Daqing Formation is host rock. The Pb-Zn orebodies occur in stratoid form and are controlled by interlayer fissures in the eastern limb of the Heishuihe anticline, belonging to typical sedimentary-reformed deposit.
