| Abstract: | After a discussion on the geological features of Caledonian granites in the eastern sectorof East Kunlun, the authors held that the genetic types of Caledonian granites were very complex andabundant, including island - arc type, collission type and inner- continent orogenic type, and so on.All these reflect that the eastern sector of East Kunlun was subjected a complex dynamics process ofocean - continent subduction and continent - continent collision in Caledonian Cycle. |
