Indian Plate in the context of "Balochistan"

There are at least 108 mountains on Earth with elevations of 7,200 m (23,622 ft; 4 mi) or greater above sea level. Of these, 14 are more than 8,000 m (26,247 ft; 5 mi). The vast majority of these mountains are part of either the Himalayas or the Karakoram mountain ranges located on the edge of the Indian Plate and Eurasian Plate in China, India, Nepal, and Pakistan.

The Geography of Pakistan (Urdu: جغرافیۂ پاکِستان, romanized: Juġarāfiyā-Pākistān) encompasses a wide variety of landscapes varying from plains to deserts, forests, and plateaus ranging from the coastal areas of the Arabian Sea in the south to the mountains of the Karakoram, Hindukush, Himalayas ranges in the north. Pakistan geologically overlaps both with the Indian and the Eurasian tectonic plates where its Sindh and Punjab provinces lie on the north-western corner of the Indian plate while Balochistan, most of Khyber Pakhtunkhwa, and Gilgit-Baltistan lie within the Eurasian plate which mainly comprises the Iranian Plateau and the Tibetan Plateau in the north.

Pakistan is bordered by Iran to the west, Afghanistan to the northwest, India to the east, and the Arabian sea to the south. Geopoltically, the nation is situated within some of the most hostile regional boundaries, characterized by territorial disputes and historical tensions, particularly the Kashmir conflict with India, which has led to multiple military confrontations between the two countries.

Balochistan (/bəˈloʊtʃɪstɑːn, bəˌloʊtʃɪˈstɑːn, -stæn/ bə-LOHTCH-ist-a(h)n, -⁠A(H)N; Balochi: بلۏچستان, romanized: Balòcestàn, [baˈloːt͡ʃest̪ɑːn]), also spelled as Baluchistan or Baluchestan, is a historical region in West and South Asia, located in the Iranian plateau's far southeast and bordering the Indian Plate and the Arabian Sea coastline. This arid region of desert and mountains is primarily populated by ethnic Baloch people.Balochistan is very significant because of its strategic location, mineral wealth, long coastline along the Arabian Sea, the Gulf of Oman and potential for discoveries of oil and gas.

The Balochistan region is split among three countries: Iran, Afghanistan and Pakistan. Administratively it comprises the Pakistani province of Balochistan; the Iranian province of Sistan and Baluchestan, along with southern Kerman province, southern South Khorasan province and eastern Hormozgan province; and the southern areas of Afghanistan, which include Nimruz, Helmand and Kandahar provinces. It borders what was historically the Pashtunistan region to the north, Sindh and Punjab to the east, and southeastern Iran to the west. Its southern coastline, including the Makran Coast, is washed by the Arabian Sea, in particular by its western part, the Gulf of Oman.

Insular India was an isolated landmass which became the Indian subcontinent. Across the latter stages of the Cretaceous and most of the Paleocene, following the breakup of Gondwana, the Indian subcontinent remained an isolated landmass as the Indian Plate drifted across the Tethys Ocean, forming the Indian Ocean. The process of India's separation from Madagascar first began 88 million years ago, but complete isolation only occurred towards the end of the Maastrichtian, a process that has been suggested to be the creation of the Deccan Traps. Soon after, the land mass moved northward rather quickly, until contact with Asia was established 55 million years ago. Even then, both landmasses did not become fully united until around 35 million years ago, and periods of isolation occurred as recently as 24 million years ago.

Thus, for a period of 53 million years India retained a degree of isolation, 11 of which it was a complete island continent. This allowed its local biota to follow the typical patterns seen in islands and diversify in unique ways, much as in modern Madagascar, its sister landmass. Faunal interchanges with other landmasses, like Africa and Europe (then an archipelago of islands across the Tethys) occurred during this period, and a considerable Asian influence can already be seen long before contact was made. This rendered India rather peculiar as not just an isolated continent but also a "stepping stone" in the dispersal of many animal and plant clades across Africa, Europe, Madagascar, Asia and possibly even Oceania. Still, several "archaic" clades managed to survive. The vast majority of India's terrestrial vertebrate life was wiped out in the Cretaceous-Paleogene extinction event; only 3 extant tetrapod lineages can trace their ancestry to Cretaceous India. Most of India's few other surviving Gondwanan lineages were outcompeted during the Paleogene by newly-arriving lineages. However, plants and invertebrate fauna were less affected.

The Mascarene Islands (English: /mæskəˈriːn/; French: Mascareignes [maskaʁɛɲ] ) or Mascarenes or Mascarenhas Archipelago is a group of islands in the Indian Ocean east of Madagascar consisting of islands belonging to the Republic of Mauritius as well as the French department of Réunion. Their name derives from the Portuguese navigator Pedro Mascarenhas, who first visited them in April 1512. The islands share a common geological origin beneath the Mascarene Plateau known as the Mauritia microcontinent which was a Precambrian microcontinent situated between India and Madagascar until their separation about 70 million years ago. They form a distinct ecoregion with unique biodiversity and endemism of flora and fauna.

In geology, a forebulge is a flexural bulge in front as a result of a load on the lithosphere, often caused by tectonic interactions and glaciations. An example of forebulge can be seen in the Himalayan foreland basin, a result of the Indian-Eurasian (continent-continent) plate collision, in which the Indian plate subducted and the Eurasian plate created a large load on the lithosphere, leading to the Himalayas and the Ganges foreland basin.

The geology of the Himalayas is one of the most dramatic and visible creations of the immense mountain range formed by plate tectonic forces and sculpted by weathering and erosion. The Himalayas, which stretch over 2400 km between the Namcha Barwa syntaxis at the eastern end of the mountain range and the Nanga Parbat syntaxis at the western end, are the result of an ongoing orogeny — the collision of the continental crust of two tectonic plates, the Indian Plate thrusting into the Eurasian Plate. 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. Topographically, the belt has many superlatives: the highest rate of uplift (nearly 10 mm/year at Nanga Parbat), the highest relief (8848 m at Mt. Everest Chomolangma), among the highest erosion rates at 2–12 mm/yr, the source of some of the greatest rivers and the highest concentration of glaciers outside of the polar regions.

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. From south to north, the zones and the major faults separating them are the Main Frontal Thrust (MFT), Subhimalaya Zone (also called Sivalik), Main Boundary Thrust (MBT), Lesser Himalaya (further subdivided into the "Lesser Himalayan Sedimentary Zone (LHSZ) and the Lesser Himalayan Crystalline Nappes (LHCN)), Main Central thrust (MCT), Higher (or Greater) Himalayan crystallines (HHC), South Tibetan detachment system (STD), Tethys Himalaya (TH), and the Indus‐Tsangpo Suture Zone (ISZ). North of this lies the Transhimalaya in Tibet which is outside the Himalayas. 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.
