Thermal evolution of the Gangdese batholith, southern Tibet: a history of episodic unroofing
Article Abstract:
28 rocks from 10 Gangdese granitoid plutons of the batholith in the Lhasa region were fission-track and 40Ar/39Ar analyzed to provide a detailed understanding of the age and the tectonic and postcrystallization erosional history of the rocks. A marked discontinuity is displayed by the postcrystallization cooling histories of all these plutons. The initial cooling of hot magma against cold country rock displayed evidence for one or more subsequent periods of rapid cooling, dropping many tens of degrees in a few million years. The ages for these plutons are of 94 to 42 Ma, with a majority being of Tertiary age.

Eocene-early Miocene foreland basin development and the history of Himalayan thrusting, western and central Nepal
Article Abstract:
Foreland basin development and significant crustal thickening in the Himalaya were occurring by middle Eocene time in western and central Nepal, according to sedimentologic, subsidence and provenance data from Cretaceous through lower Miocene sedimentary rocks in the southern area of the Himalayan fold-thrust belt. When regarded within the framework of a southward migrating foreland basin system, the thick sandstone bodies in the lower area of the Dumri Formation could be the channel deposits of an axial fluvial system in the distal foredeep, flowing toward the west-southwest into the Indus foreland.
