A review of genesis study on magmatic rocks of the Qinghai-Tibet Plateau: achievements and remaining problems

The Qinghai-Tibet Plateau is a well-known natural laboratory on the study of continental dynamics for all the international geosciences community. Magmas are important carriers for transferring mass and heat among the Earth's sphere layers. Igneous rocks and the carrying deep-seated rock exclusions can be considered as "probe" and "window" to help us understanding the interior part of the earth, and they are records for plate movement and geo-tectonic events. The paper has reviewed the studies on the origins of the igneous rocks, especially the generation and evolution of magmas, including both the achievements and the remaining problems. The origins of various igneous rocks in the Qinghai-Tibet Plateau were discussed, respectively. Those include the Linzizong volcanics, the syn-collisional Gangdese granitoids, the potassic-ultrapotassic volcanics, the adakites and adakitic rocks, the strong peraluminous granites, the mantle plume-related igneous rocks, the lower crustal and mantle xenoliths and outcrops, and the Indian/ Tethyan oceanic geochemical domain.
