The Titiwangsa Mountains (Malay: ''Banjaran Titiwangsa''; بنجرن تيتيوڠسا), also known as ''"Banjaran Besar"'' (Main Range) by locals, are the main mountain range that forms the backbone of the Malay Peninsula. The northern section of the range is in Southern Thailand, where it is known as Sankalakhiri Range ((タイ語:ทิวเขาสันกาลาคีรี), ). The range acts as a natural divider, dividing Peninsular Malaysia, as well as southernmost Thailand, into East and West Coast regions. The length of mountain range is about 480 km from north to south. ==Geology== The Titiwangsa Mountains is part of suture zones that runs north-south, starting in Thailand (Nan-Uttaradit/Dien Bien Phu suture zone) and extending south towards peninsular Malaysia (Bentong-Raub suture zone). The western half of Titiwangsa Mountains in peninsular Malaysia is an amalgamation of continental terranes that is known as Cimmeria or Indochina, whereas the eastern half is an amalgamation of continental terranes Sinoburmalaya or Sibumasu. These two halves of terranes were separated by Paleo-Tethys Ocean.〔Metcalfe, I., 2000, The Bentong-Raub Suture Zone: Journal of Asian Earth Sciences, v. 18, p. 691-712〕〔Metcalfe, I., 2002, Permian tectonic framework and palaeogeography of SE Asia: Journal of Asian Earth Sciences, v. 20, p. 551-566〕 The Cimmeria was separated from Gondwana around 400mya during Devonian and rifted towards Laurasia, the northeastern arm of Pangea. It attached to Laurasia completely around 280mya during Late Permian Sibumasu terranes on the other hand, only started to separate from Gondwana during Early Permian and rifted towards Indochina. The collision of Sibumasu terranes and Indochina terranes during 200mya Late Triassic resulted in the closure of the Paleo-Tethys Ocean and formation of the modern Titiwangsa Mountain belts. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Titiwangsa Mountains」の詳細全文を読む スポンサード リンク
