Tectonic evolution of the central Annapurna Range, Nepalese Himalayas
The metamorphic core of the Himalayan orogen, or Greater Himalayan sequence, is a northward tapering prism bound at the bottom by a N dipping family of thrust faults (the Main Central thrust system)Expand
Himalayan metamorphic sequence as an orogenic channel: Insight from Bhutan
The Bhutan Himalayas differ from the rest of the Himalayas in two major ways: (i) low-grade sedimentary rocks lie above the Greater Himalayan Sequence as klippen (i.e. erosional remains of the SouthExpand
U–Pb dating of monazite and its application to geological problems
Monazite is an underutilized mineral in U–Pb geochronological studies of crustal rocks. It occurs as an accessory mineral in a wide variety of rocks, including granite, pegmatite, felsic volcanicExpand
Isotopic constraints on the age and provenance of the Lesser and Greater Himalayan sequences, Nepalese Himalaya
The Main Central thrust of the central Himalaya juxtaposes the Lesser Himalayan sequence (footwall) with the Greater Himalayan sequence (hanging wall), both of which are regarded as components of theExpand
The structural geometry, metamorphic and magmatic evolution of the Everest massif, High Himalaya of Nepal–South Tibet
This paper presents a new geological map together with cross-sections and lateral sections of the Everest massif. We combine field relations, structural geology, petrology, thermobarometry andExpand
Exhumation of the Main Central Thrust from Lower Crustal Depths, Eastern Bhutan Himalaya
Geothermometry and mineral assemblages show an increase of temperature structurally upwards across the Main Central Thrust (MCT); however, peak metamorphic pressures are similar across the boundary,Expand
Geophysics and geochronology of the crystalline basement of the Alberta Basin, western Canada
Although progressively muted by the increasing thickness of Phanerozoic sediments in the Alberta Basin, the geophysical signature of tectonic domains in the Canadian Shield can be traced nearly toExpand
Eocene extensional tectonics and geochronology of the Southern Omineca Belt, British Columbia and Washington
Eocene extension contributed significantly to the present crustal architecture of the southern Omineca Belt in British Columbia and Washington. High grade gneiss complexes (Valhalla, Okanagan,Expand
Crustal thickening leading to exhumation of the Himalayan Metamorphic core of central Nepal: Insight from U‐Pb Geochronology and 40Ar/39Ar Thermochronology
New and published U-Pb geochronology and 40Ar/39Ar thermochronology from footwall and hanging wall rocks of a segment of the South Tibetan detachment system exposed in the Annapurna area of centralExpand
Timing of India‐Asia collision: Geological, biostratigraphic, and palaeomagnetic constraints
[1] A range of ages have been proposed for the timing of India-Asia collision; the range to some extent reflects different definitions of collision and methods used to date it. In this paper weExpand
