The Himalaya offers many opportunities to study all factors that go into mountain building such as continental collisions, erosion, and even climatic changes. In order to understand the structural complexity of the Himalaya orogen, understanding the South Tibet detachment is critical to figuring out the exact time and processes involved in the ...
From south to north the Himalaya (Himalaya orogen) is divided into 4 parallel tectonostratigraphic zones and 5 thrust faults which extend across the length of Himalaya orogen. Each zone, flanked by the thrust faults on its north and south, has stratigraphy (type of rocks and their layering) different from the adjacent zones.
The Alpide belt or Alpine-Himalayan orogenic belt, [1] or more recently and rarely the Tethyan orogenic belt, is a seismic and orogenic belt that includes an array of mountain ranges extending for more than 15,000 kilometres (9,300 mi) along the southern margin of Eurasia, stretching from Java and Sumatra, through the Indochinese Peninsula, the Himalayas and Transhimalayas, the mountains of ...
The Himalaya orogenic belt the highest elevated mountain range on Earth. In summer, air mass across the South Asia is heated up in general. On the contrary, airmass above the Himalayas and Tibet experiences adiabatic cooling and sinks rapidly, forming an intense high pressure cell. This cell is therefore capable of facilitating landward airflow ...
The Lesser Himalayan Sequence is a unit emplaced before the mountain-building processes. [3] The Greater Himalayan Crystalline complex represents a high-grade unit moved towards SW from the hinterland. The Tethyan Himalayan Sequence represents strata deposited in the former passive margin in the Northern edge of Indian plate. [11] [12]
The Himalaya's foothills or sub-Himalaya are Miocene to Pleistocene sediments that have eroded off the mountain range during its uplift. These sedimentary rocks have been highly deformed by the continued uplift of the Himalaya. The upper Proterozoic to lower Cambrian Lesser Himalaya sedimentary rocks represent the Himalaya's main range front ...
Science. 1992 Mar 27;255(5052):1663-70. [3] Yin A. Cenozoic tectonic evolution of the Himalayan orogen as constrained by along-strike variation of structural geometry, exhumation history, and foreland sedimentation.
The thickening of the crust marks the start of an orogeny, or "mountain building event." As the orogeny progresses, the orogen may start spreading apart and thinning. Collapse processes can begin either once the orogeny ends as the tectonic forces cease, or during the orogeny if the crust becomes unstable. [1]
