 note = {The metamorphic pressure conditions at peak-T show a high field pressure gradient (c. 1.2-1.6 kbar/km) near the Main Central Thrust (MCT), which juxtaposes the high-grade Higher Himalayan Crystalline Sequences (HHCS) over the low-grade Lesser Himalaya Sequences (LHS) in far-eastern Nepal. Maximum recorded pressure conditions occur just above the MCT (-11 kbar), and decrease southward to -6 kbar in the garnet zone and northward to -7 kbar in the kyanite ± staurolite zone. Exhumation of the lowermost HHCS from deeper crustal depths than the flanking regions is perhaps caused by ductile extrusion along the MCT, not the emplacement along a single thrust. The peak metamorphic temperatures show a progressive increase of temperature structurally upward (c. 570 to 740 ℃) near the MCT and roughly isothermal conditions (c. 710-810 ℃) in the upper structural levels of the HHCS. The observed field temperature gradient is much lower than those predicted in channel flow models. However, the discrepancy could be resolved by taking into account heat advection by melt and/or fluid migrations, as these can produce low or nearly no field temperature gradient in the exhumed midcrust, as observed in nature., 第22回名古屋大学年代測定総合研究センターシンポジウム平成21(2009)年度報告},
