... with other models appropriate for the region. We found a high amount of microseismicity throughout southern Bhutan and almost no seismicity under northern Bhutan and southern Tibet. Our results showed that analysis of data from small in-country seismic networks resulted in new scientific findings...

... units of the central Himalaya. The High Himalayan Series dominates the geology of Bhutan ( Gansser, 1983 ; Fig. 2 ). In southern Bhutan, klippen of Tethyan sediments are in normal fault contact with the upper sequence of these metamorphic rocks along the South Tibetan detachment. Davidson et al...

... to these differences. Not many studies have thus far provided constraints on the timing of metamorphism in central and western southern Bhutan. Monazite cores yielding ages ≥21 Ma have been interpreted as documenting the timing of prograde metamorphism to conditions of c. 700°C and 8 kbar in the GHS surrounding...

... and the local chemical environment. In situ U-Pb and Hf isotope analyses of zircon rims from Oligocene–Miocene leucogranites of the Bhutan Himalaya reveal, for the first time, an evolution in melt composition between 32 and 12 Ma. The data indicate a uniform melt source from 32 Ma to 17 Ma, and the progressive...

... with this physiographic transition in eastern Bhutan—the Lhuentse fault. Low-temperature (U-Th)/He apatite data suggest that the Lhuentse fault has been active since the Pliocene, and (U-Th)/He dates on offset hydrothermal hematite deposits from within the fault zone demonstrate a component of Quaternary slip. Although...
