| 摘 要： | 广东银岩斑岩锡矿床位于云开地背斜与湘赣粤地向斜的交接部位,受吴川—四会大断裂与大田顶弧形构造联合控制。矿床在时间、空间和成因上都与花岗斑岩体有关。该矿床矿化均匀,品位较富,矿石结构构造、矿物成份较简单,属大型锡矿床。含矿花岗斑岩岩浆为来自上地幔的混合源同熔型,成矿物质主要来自上地幔,部分来自围岩,为典型的高中温气成热液斑岩型锡矿床。 |

| Abstract: | The porphyry tin ore deposit is located in the joint part of Yunkai geoanticline and Hunan-Jiangxi-Guangdong geosycline, controlled by both wu-chuan-Sihui great fracture and Datianding arc structure. The deposit is connected with granoporphyry body in time, space and genesis. The ore deposit is characteristic of uniform mineralization, higher quality, and simple ore structure and texture and mineral composition, belonging to the big one. The ore-bearing granoporphyry magma is of mixed syntexis type coming from the upple mantle,and the minerogenetic material comes mainly from the upple mantle, partially from the surrounding rock. It is a typical hypo-mesothermal tin ore deposit of porphyry type. |
