| 1 | The tin deposits are occurred as the veins in the southern part of the Qitianling composite granite body and its contact zone. | |
| 2 | The Furong tin orefield, located in southern Hunan, China, is a newly-discovered super-large tin orefield. | |
| 3 | Qitianling pluton was formed by two phases of emplacement, and is mainly composed of early stage granite. | |
| 4 | Finally, a case study was made in the Qitianling granite complex, which is essentially composed of the Sn granites of Furong and Cailing, and the Xintianling W granite. | |
| 5 | 因此本文认为，黄沙坪花岗岩体与千里山、骑田岭等岩体属于同一类型，岩石成因可能与印支造山运动后的岩石圈伸展有关，形成于地壳物质的部分熔融。 They are the same type granitoid. Their lithogenesis was related to the lithospheric extension after the Indosinian Orogenesis, and formed from partial melting of the crust material. |
