摘要
亚杂铅锌矿含矿母岩为英安斑岩,属石英脉型,受印支晚期-燕山期张扭性断裂控制,沿断裂两侧由弱到中等线性蚀变,有较好的元素异常。结合东矿带地球化学异常元素组合、岩性、构造、蚀变特征等,认为卓玛及莫磨亚两地化探异常以铅锌元素组合为主,规模大和浓度高,是区内形成中-大型铅锌矿床最为有利地区。
The ore - bearing mother rock of Yaza Pb - Zn deposit is the dacite porphyry＇, which belongs to the quartz vein type and is controlled by the Late Indosinian- Yanshanian tension -torsion fault.There is the linear alteration from weak to medium degree along both sides of the fault and the good element anomaly. In combination with tile element assemblage of geochemical anomaly, lithological character, structure and alteration, etc, we think that the main element assemblage of geochemical anomaly at Zhuoma and Momoya is the Pb - Zn, which are in large scale and high concentration. They are the advantageous areas for form- ing the middle- large scale Pb -Zn deposit.
