(A) Map illustrating major tectonostratigraphic domains and zircon source areas within the Himalaya, which are relevant to this study, modified and simplified from7 with data from3,4,10. STD = South-Tibetan Detachment, MCT = Main Central Thrust, MBT = Main Boundary Thrust, MFT = Main Frontal Thrust, Nanga Parbat = western syntaxis, Namche Barwa = eastern syntaxis. The Indus-Yarlong suture zone (Indus-Tsangpo or ITS in the text) separates Asia from India. (B) Normalized kernel-density estimates (KDEs) for zircon (bedrock and detrital) U-Pb ages from major tectonostratigraphic domains calculated from data published in37. Here and in Fig. 3, populations A-G represent informal groups for discussion purposes. GHS plutons are schematic, and plot does not include Mesozoic and Cenozoic ages from Lhasa or the eastern syntaxis. (C) Normalized KDEs for the modern Ganges and Brahmaputra Rivers, compared with a composite plot for all Bengal Fan samples. Distinctive peaks as shown for the modern Ganges and Brahmaputra Rivers.
