华南加里东期金矿床分布广泛 ,既可产在华南加里东褶皱带内 ,也可发育在毗邻的江南隆起上。其共同特征是矿床产在加里东期构造变形带或变质带中 ,受深大断裂带及其分支构造所控制 ,成矿物质主要来自赋矿围岩。产在隆起上的矿床赋矿围岩时代较老 ,均为元古宙变质细碎屑岩类 ;矿物及元素组合比较简单 ,常见单金型。产于褶皱带中者其围岩除元古宙 -寒武纪变质细碎屑岩外 ,还有火山岩、侵入岩及沉积岩 ,时代为元古宙——志留纪 ;矿物及元素组合比较复杂 ,可见到砷、锑、汞、碲矿物及沥青出现。隆起上的矿床属于加里东期改造作用形成 ,褶皱带中者为改造、受改造及斑岩成矿作用的产物。成矿时代除加里东期外 ,还有燕山期及震旦纪矿化存在。两种构造中的矿床成矿差异主要受物质来源岩石类型、后期叠架作用及岩浆活动所控制
South China Caledonian gold deposits are widely distributed, both in the South China Caledonian fold belt, but also in the adjacent Jiangnan uplift. The common feature is that the ore deposit is produced in the Caledonian structural deformation zone or metamorphic zone and is controlled by the deep major fault zone and its branch structure. The ore-forming material mainly comes from the ore-bearing surrounding rock. The ore-bearing rocks on the uplift are older in mineralization and are all metamorphic fine clastic rocks; minerals and elemental assemblages are relatively simple and common single gold type. Occurred in the fold belt of its surrounding rock in addition to Proterozoic-Cambrian metamorphic fine clastic rock, there are volcanic rocks, intrusive rocks and sedimentary rocks, the age of Proterozoic - Silurian; mineral and elemental composition is more complex , We can see arsenic, antimony, mercury, tellurium minerals and bitumen appear. The mineralization on the uplift belongs to the Caledonian reformation and the fold belt is the product of transformation, alteration and porphyry mineralization. In addition to the Caledonian mineralization era, as well as the Yanshanian and Sinian mineralization exist. The mineralization differences between the two structures are mainly controlled by the rock type of the material source, the superimposition of late phases and the magmatism
