淘锡湖锡多金属矿床为广东莲花山断裂带南西段的一个斑岩-热液脉型锡多金属矿床。矿体产于花岗斑岩及其外接触带热水洞组火山岩地层中。主要工业矿物为锡石、闪锌矿和黄铜矿,矿石组构类型主要有它形—半自形晶粒结构,交代结构,具细脉状构造、浸染状构造、角砾状构造及团块状构造,主要围岩蚀变有硅化、绿泥石化、石榴石化。控矿因素主要有:花岗斑岩及其接触带附近,花岗斑岩周围的NE向与NW向断层次级脆-韧性断裂,尤其是几组断层交汇部位,以及较强的硅化、绿泥石化、石榴石化等围岩蚀变特征。
The Amoy Tin-tin-polymetallic deposit is a porphyry-hydrothermal vein tin-polymetallic deposit in the southwestern segment of the Lianhuashan fault belt in Guangdong Province. Orebody is produced in volcanic rocks of granite porphyry and outer contact hot water cave group. The main industrial minerals are cassiterite, sphalerite and chalcopyrite. The types of ore composition are mainly its shape-semicircle grain structure, metasomatic structure, vein-shaped structure, disseminated structure, brecciated structure and group Block structure, the main wall rock alteration silicification, chloritization, garnet. The ore-controlling factors are mainly the secondary brittle-ductile faults of NE and NW faults around the granite porphyry and its contact zone and the granite porphyry, especially the intersections of several sets of faults, and the strong silicification and greening Debris, garnet and other wall rock alteration characteristics.
