文摘

•: Middle Triassic ultrapotassic magmatism occurred in southern Qiangtang, Tibet.
•: The rhyolites originated from mixed old sedimentary and juvenile material.
•: This felsic magmatism was associated with subduction of the BNTO.
•: The time of northward subduction of the BNTO was older than previously considered.
•: Magma underplating and accretion made an important contribution to crustal growth.
