The Himalayan tectonics result in long term deformation. This includes shortening across the Himalayas that range from 900 to 1,500 km. Said shortening is a product of the significant ongoing seismic activity. The continued convergence of the Indian plate with the Eurasian plate results in mega earthquakes.
A hypothetical lost oceanic plate called the Kshiroda Plate is supposed to have existed between the two subduction zones. It is now believed that this oceanic plate is actually a broken-off fragment of the above mentioned "Neo-Tethys oceanic basin". The bed of the Tethys sea lay on the Kshiroda Plate and was carried along with it towards Eurasia.
Scientists have known that the collision of the two tectonic plates, which began roughly 60 million years ago, caused the edge of the Eurasian plate to buckle, bulging and twisting into what we ...
Pre-collisional Himalaya is the arrangement of the Himalayan rock units before mountain-building processes resulted in the collision of Asia and India. The collision began in the Cenozoic and it is a type locality of a continental-continental collision. [2]
The Himalayas, or Himalaya (/ ˌ h ɪ m ə ˈ l eɪ. ə, h ɪ ˈ m ɑː l ə j ə / HIM-ə-LAY-ə, hih-MAH-lə-yə) [b] is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has several peaks exceeding an elevation of 8,000 m (26,000 ft) including Mount Everest, the highest mountain on ...
The Alpine orogeny is caused by the continents Africa, Arabia and India and the small Cimmerian Plate colliding (from the south) with Eurasia in the north. Convergent movements between the tectonic plates (the African Plate, the Arabian Plate and the Indian Plate from the south, the Eurasian Plate and the Anatolian Sub-Plate from the north, and many smaller plates and microplates) had already ...
Crustal thickening has an upward component of motion and often occurs when continental crust is thrust onto continental crust. Basically nappes (thrust sheets) from each plate collide and begin to stack one on top of the other; evidence of this process can be seen in preserved ophiolitic nappes (preserved in the Himalayas) and in rocks with an inverted metamorphic gradient.
Lopian orogeny – Archean orogeny – Formation of two different types of terrain compatible with plate tectonic concepts. One is a belt of high-grade gneisses formed in a regime of strong mobility, while the other is a region of granitoid intrusions and greenstone belts surrounded by the remnants of a Saamian substratum, (2.9–2.6 Ga)
