| Abstract: | Granites were extensively distributed over Southern Hunan. Greisenization in varing degree was developed at the front and top of granites, or along two fracture surface of fracture which occurred in granites. In the course of greisenization, abundant accumulation of Li, Rb, Cs and formation of cassiterite and wolframite led up to forming greisen type, greisen quartz-vein type Sn(W)-deposits, or Rb polymetallic deposits. These deposits possess common and different characteristics in aspects of orebody occurrence, mineral composition, greisen type, chemical composition of ore and so on. This kind of Sn-deposit is very important tin source in Southern Hunan. |
