一、矿区简况阳春黑石岗矿区位于广东湛江地区,硫铁矿床中溶洞矿矿体赋存于黑石岗背斜两侧。背斜轴部为燕山期花岗闪长岩,翼部为下石炭统石磴子段大理岩、灰岩。矿体产于接触带。主矿体呈似层状产于背斜的北西侧。矿床中银、铅、锌的硫化物溶洞矿矿体,多受原生硫铁矿或矿区后期构造的控制。溶洞矿在空间上多与黄铁矿体紧密共生,其赋存标高多 I. Brief Introduction of Mining Area Yangshuang Blackstone Mine is located in Zhanjiang, Guangdong. Karst cave ore bodies in the pyrite deposit exist on both sides of the anticline of Blackstone. The anticline axis is Yanshanian granodiorite, and the wing is marble and limestone of the Lower Carboniferous Shijiazhuang sub-section. Ore body produced in the contact zone. The main orebody is laminar in the northwest side of the anticline. Deposits of silver, lead, zinc sulphide cave minerals, mostly by the native pyrite or the control of post-tectonic mining area. Karst caves in the space more closely with the pyrite coexistence, its occurrence of elevation and more
