摘要
本文依据新发现的2条矿化带的地质地球化学特征,讨论了四川布拖县包谷坪铅锌矿的矿床成因。矿床产于奥陶系大菁组二段白云岩内,矿体受地层层位和北东向断层控制,硅化、褐铁矿化明显。矿床属于构造热液蚀变岩型。提出了地层、岩性、构造、蚀变、地貌、遥感和地球化学的找矿标志和下一步工作的建议。
This paper has a discussion on ore genesis of the Baoguping Pb-Zn deposit in Butuo, Sichuan based on geological and geochemical features of the newly found out 2 mineralized zones. The Pb-Zn ore is confined to dolomitite of the Second Member of the Ordovician Dajing Formation and controlled by stratigraphical horizon and NE-trending faults and associated with obvious silicification and limonitization. The Pb-Zn deposit belongs to tectonic hydrothermal alteration rock type. Stratigraphical, lithological, tectonic, geomorphic, remote sensing, wallrock alteration and geochemical ore guides as well as suggestions on geological work in the future are put forward.
