The metamorphism and exhumation of the Himalayan metamorphic core, eastern Garhwal region, India
[1] Geothermobarometric together with microand macro-structural data indicate ductile flow in the metamorphic core of the Himalaya in the Garhwal region of India. Peak metamorphic pressure and temperature increase dramatically across the Main Central Thrust (MCT) from !5 kbar and !550°C in the Lesser Himalayan Crystalline Sequence (LHCS) to !14 kbar and !850°C at !3 km above the MCT in the Grea...
متن کاملLateral extrusion, underplating, and out-of-sequence thrusting within the Himalayan metamorphic core, Kanchenjunga, Nepal
Integrated pseudosection modeling and monazite petrochronology of paragneiss from the Kanchenjunga region of northeastern Nepal reveal the presence of cryptic tectonometamorphic discontinuities within the Himalayan metamorphic core. These new data outline a series of thrust-sense structures that juxtapose rocks that generally record a protracted history of early Eocene to latest Oligocene–early...
متن کاملTiming of granulite-facies metamorphism in the eastern Himalayan syntaxis and its tectonic implications
We present geochronological evidence in the eastern Himalayan syntaxis (Namche Barwa) for high-pressure (HP) granulite-facies metamorphism and explain its importance for understanding both the deep continental subduction of the Indian plate beneath Asia and its subsequent exhumation. The timing of peak and retrograde metamorphism in part constrains these processes but is debated. We present zir...
متن کاملHimalayan Folklore and the Fairy Tale Genre
Based on fieldwork by the author conducted in Tibetan cultural areas of the Indian Himalayas, this paper explores Himalayan understandings of what defines a fairy tale, in contrast to the Western understanding. In parts of the Himalayas, a distinction is made between “lakshung” (fairy tales) and “kyakshung”, which are shorter stories, the kind one might tell over tea. In light of the proposals ...
