Cenozoic K-Rich Adakitic Volcanic Rocks in the Hohxil Area:Lower-Crust Partial Melting in an Intracontinental Setting
It is generally accepted that the Cenozoic potassic volcanic rocks of northern Tibet were derived from a lithospheric mantle source.Cenozoic rocks reported in Gangdisi (south Tibetan Plateau) have received attention because of the apparent absence of a contemporaneous proximal subduction zone.The Gangdisi area was in an arc setting from the Mesozoic to the early Tertiary, and an active collision zone between the Indian and Asian continents exists nearby, others have argued that these adakitic magmas could have originated by partial melting of subducted oceanic crust, involving incorporation of melts from sediments and mantle-wedge components (Qu et al., 2004). Thus, the origin of Cenozoic adakites in southern Tibet remains controversial.
