China–Myanmar border in the context of Geology of the Himalaya

⭐ Core Definition: China–Myanmar border

The China–Myanmar border is the international border between the territory of the People's Republic of China and Myanmar (formerly Burma). The border is 2,129 km (1,323 mi) in length and runs from the tripoint with India in the north to the tripoint with Laos in the south.

👉 China–Myanmar border in the context of Geology of the Himalaya

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.

China–Myanmar border in the context of Borders of China

The People's Republic of China (PRC) shares land borders with 14 countries (tied with Russia for the most in the world): North Korea, Russia, Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, India, Nepal, Bhutan, Myanmar, Laos, and Vietnam, and with two Special administrative regions of China, Hong Kong and Macao. The land borders, counterclockwise from northeast to southwest, are the China–North Korea border, the eastern segment of the China–Russia border, the China–Mongolia border, the western segment of the China–Russia border, the China–Kazakhstan border, the China–Kyrgyzstan border, the China–Tajikistan border, the China–Afghanistan border, the China–Pakistan border, the western segment of the China–India border (the most contested of the Sino-Indian border dispute), the China–Nepal border, the central segment of the China–India border (Sikkim), the China–Bhutan border, the eastern segment of the China–India border, the China–Myanmar border, the China–Laos border, the China–Vietnam border, a 3-kilometre (1.9 mi) internal border with Macau, a Portuguese territory until 1999, and a 30-kilometre (19 mi) internal border with the special administrative region of Hong Kong, which was a British dependency before 1997.

To the west, China has maritime borders with North Korea, Japan and contested limits with Taiwan and other countries in the South China Sea, among other territorial disputes.

China–Myanmar border in the context of Namcha Barwa Himal

Namcha Barwa Himal, also known as Namjagbarwa syntaxis or Namjagbarwa Group Complex, is the easternmost section of the Himalaya in southeastern Tibet and northeastern India. This section spans 180 km from the headwaters of the Siyom River on the international border NE into Tibet to the canyon of the Yarlung Tsangpo (the Brahmaputra in India), where the Himalaya are said to end, although high ranges (Hengduan Mountains on China–Myanmar border) actually continue another 300 km east.

China–Myanmar border in the context of Namche Barwa

Namcha Barwa or Namchabarwa (Tibetan: གནམས་ལྕགས་འབར་བ།, Wylie: Gnams lcags 'bar ba, ZWPY: Namjagbarwa; Chinese: 南迦巴瓦峰, Pinyin: Nánjiābāwǎ Fēng) is a mountain peak lying in Tibet in the region of Pemako. The traditional definition of the Himalaya extending from the Indus River to the Brahmaputra would make it the eastern anchor of the entire mountain chain, and it is the highest peak of its own section as well as Earth's easternmost peak over 7,600 metres (24,900 ft). It lies in the Nyingchi Prefecture of Tibet. It is the highest peak in the 180 km long Namcha Barwa Himal range (also called the Namjagbarwa syntaxis or Namjagbarwa Group Complex), which is considered the easternmost syntaxis/section of the Himalaya in southeastern Tibet and northeastern India where the Himalaya are said to end, although high ranges (Hengduan Mountains on the China–Myanmar border) actually continue another 300 km to the east.
