摘要
打厂凹金铁铜铅锌矿赋存于核桃坪紧密性破背斜近核部沙河厂组一段与核桃坪组三段地层接触带中,具“地层(岩性)+构造+岩浆活动”三位一体控矿规律。矿体上部受近南北向断裂控制,多形成“裂控”型矿床;下部受沙河厂组及与核桃坪组接触面、核桃坪组不同岩性结构面控制,多形成“层控”型矿床;呈“背斜核部夹一刀”控矿特征。地表及北部为金铅锌矿体、地下及南部为铜铅锌矿体特征。为构造-岩浆热液有关的热液-矽卡岩复合型矿床。
The Dachangao Au-Fe-Cu-Pb-Zn deposit is located in the near-core part of the Hetaoping anticline,and in the contact zone between the first member of the Shahechang Formation and the third member of the Hetaoping Formation.It has a trinity ore-controlling law of'stratum(lithology)+structure+magmatic activity'.The upper part of the ore body is controlled by the nearly north-south fault,and the'fault control type deposit is formed.The lower part is controlled by the Shahechang Formation and the contact surface with the Hetaoping Formation,as well as different lithological structural planes of the Hetaoping Formation,resulting in the formation of'layer controlled type deposits.The surface and north of the mining area are Au-Pb-Zn ore bodies,and the underground and south are Cu-Pb-Zn ore bodies.It is a hydrothermal-skarn composite deposit related to tectonic-magma hydrothermal fluid.
