Using cooling curves of K-feldspars obtained by using specific ~(40)Ar/~(39)Ar stepe heating procedure and multiple diffusion domain modeling (MDD model), together with results of dating hornblends, biotite, and apatite, further work has been done to examine the characteristics of the postcrystallization thermal evolution history of Gangdese batholithic zone, to compare the starting times of rapid cooling events with the variation regularities of apatite fission track (FT) ages in the eastern and western parts of Gangdese batholithic zone, and to provide the evidence for mass transport and energy transfers in the lithosphere after the collision between Indian and Eurasian plates.
