Geologic Evolution of the Himalayan-Tibetan Orogen

Annual Review of Earth and Planetary Sciences, 2000
A review of the geologic history of the Himalayan-Tibetan orogen suggests that at least 1400 km of north-south shortening has been absorbed by the orogen since the onset of the Indo-Asian collision at about 70 Ma. Significant crustal shortening, which leads to eventual construction of the Cenozoic Tibetan plateau, began more or less synchronously in ...

Simultaneous Miocene Extension and Shortening in the Himalayan Orogen

Science, 1992
The South Tibetan detachment system separates the high-grade metamorphic core of the Himalayan orogen from its weakly metamorphosed suprastructure. It is thought to have developed in response to differences in gravitational potential energy produced by crustal thickening across the mountain front.

Miocene high-temperature leucogranite magmatism in the Himalayan orogen

GSA Bulletin, 2020
AbstractHimalayan leucogranites of Cenozoic age are generally attributed to partial melting of metasedimentary rocks at low temperatures of <770 °C. It is unknown what the spatial distribution and characteristics of high-temperature (>800 °C) leucogranites are in the Himalayan orogen.

Controls on valley-floor width across the Himalayan orogen

2023
Himalayan rivers transport approximately 103 Mt of sediment annually from their source in the steep topography of the High Himalaya to ocean basins. However, the journey from source to sink is not necessarily a smooth one: on the way, sediment can become trapped in montane storage systems, such as river valleys or floodplains.

Metamorphic response to collision in the Central Himalayan Orogen

Gondwana Research, 2018
Abstract Closure of the Neotethys Ocean and high-angle continent-continent collision between India and Asia after about 55 Ma resulted in low-angle subduction of the Indian plate below the Tibetan Plateau and by ~30 Ma established an arcuate 2300 km long, shallow north-dipping metamorphic fold-thrust belt in the foreland.

Extensional tectonics in the Himalayan orogen, Zanskar, NW India

Geological Society, London, Special Publications, 1993
Abstract Large-scale nappes of the deformed Higher Himalayan Crystallines (HHC) were thrust southward over the Lesser Himalayan Proterozoic foreland during the Late Cenozoic. Critical evaluation of shear fabrics, reveals that the HHC underwent an earlier phase of ductile shearing with top-to-southwest overthrust-type sense of movement.

Kinematic reconstruction of the Tibetan-Himalayan orogen since the Cretaceous

2023
Knowledge of the kinematic evolution of the Tibetan-Himalayan orogenic system is paramount to understand the geodynamics, development of topography and climate changes in a region that contains some of the world’s most important biodiversity hotspots. The tectonic framework however has been controversial with multiple models proposed.

From tectonically to erosionally controlled development of the Himalayan orogen

Geology, 2005
Abstract Whether variations in the spatial distribution of erosion influence the location, style, and magnitude of deformation within the Himalayan orogen is a matter of debate. We report new 40Ar/39Ar white mica and apatite fission-track (AFT) ages that measure the vertical component of exhumation rates along an ∼120-km-wide NE-SW ...

Progressively elevated geothermal gradients for Miocene metamorphism in the Himalayan orogen

Geological Society of America Bulletin, 2023
The property of regional metamorphism at convergent plate margins is substantially related to the change of geothermal gradients, resulting in different types of crustal reworking through metamorphic dehydration and partial melting. The relationship between crustal metamorphism and thermal evolution of collisional orogens can thus be deciphered by ...
