Explain the himalaya mountain is formed of sedimentary rocks
Answers
Answer:
Like most mountain ranges, the Himalayas are composed of a variety of rock types, including igneous intrusive rocks, extrusive rocks, many metamorphic rocks, and some sedimentary rocks. ... Two continental blocks collided and created enormous pressure and temperature during the formation of Himalaya.
Explanation:
The Himalayas, which stretch over 2400 km between the Namche Barwa syntaxis in Tibet and the Nanga Parbat syntaxis in India, are the result of an ongoing orogeny — the result of a collision between two continental tectonic plates. The Himalaya-Tibet region supplies fresh water for more than one-fifth of the world population, and accounts for a quarter of the global sedimentary budget.
The closing and subduction of the Tethyan Ocean, located between India and Asia during the Paleozoic, followed by collision of continents produced the structures and lithologies we see today in the Himalayas. Consequently, the mountains and surrounding regions are characterized by astounding complexity,represented by a variety of deformed and collision-produced lithologies and representing several phases of tectonic and deformational events. The Himalayas can be divided into six primary lithotectonic zones that occur in parallel belts. These zones consist of the Trans-Himalayan batholith, Indus-Tsangpo suture zone, Tethyan(Tibetan) Himalaya, Higher(Greater) Himalaya, Lesser(Lower) Himalaya, and Sub-Himalaya. Tectonic environments within these zones also vary. The emense collision of plates at 45 million years gave rise to an island-arc margin in the western Himalayas and an Andean-type margin in central-to-eastern Himalayan regions (Windley 1995).
