Abstract: Through many explorations, the structural framework of the Qinghai-Xizang Plateau has been basically established, but the regionalization of the structures of the Karakoram and Kunlun Mts. region in the northwestern part of the Plateau is still not clear. In the recenr exploration, large amount of new data were obtained. It has been found that the Kude-Subashi structural zone is an independent important structural line of an earlier stage. It has also discovered that the Maza-Kangxiwar-Motzetage structural zone is connected with the Kunlua-shankou-Maqin structural zone. The above mentioned two structural zones c'ivided the Karakoram and Kunlun Mts. region into three belts, namely, north belt, middle belt, and south belt. The south belt, according to its developmental history, is linked to the Bayan Kara region and does not belong to the real Kunlun structure region.
