The Himalayas border the Indo-Gangetic Plain to the south, Pamir Mountains to the west in Central Asia, and the Hengduan Mountains to the east on the China–Myanmar border. From east to west the Himalayas are divided into 3 regions, Eastern Himalaya, Central Himalaya, and Western Himalaya, which collectively house several nations and states.
Satellite image of the Himalayas Spatial arrangement of the Himalayan tectonostratigraphic zones. Modified from N.R. McKenzie et al 2011 [1]. Pre-collisional Himalaya is the arrangement of the Himalayan rock units before mountain-building processes resulted in the collision of Asia and India.
In geology, metasedimentary rock is a type of metamorphic rock. Such a rock was first formed through the deposition and solidification of sediment. Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. The overall composition of a metasedimentary rock can be ...
This collision gradually formed the Himalayas, including the Hindu Kush. [57] The Hindu Kush are a part of the "young Eurasian mountain range consisting of metamorphic rocks such as schist, gneiss and marble, as well as of intrusives such as granite, diorite of different age and size". The northern regions of the Hindu Kush witness Himalayan ...
A geological map of the Himalaya region. The Main Himalayan Thrust underlies the rock units. Diagram showing a décollement. The Main Himalayan Thrust (MHT) is a décollement under the Himalaya Range. This thrust fault follows a NW-SE strike, reminiscent of an arc, and gently dips about 10 degrees towards the north, beneath the region.
The Lesser Himalaya also called the Lower Himalaya, or the Midlands, is a thick (about 7 km) section of para-autochthonous crystalline rocks made up of low- to medium-grade rocks. These lower Proterozoic clastic rocks [11] are subdivided into two groups.
More than 100 people have been killed after a powerful earthquake struck a remote region of Tibet on Tuesday morning, with tremors felt across the Himalayas in neighboring Nepal, Bhutan and parts ...
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 ...
