The prominent NS Palaeo-Tethys Bentong-Raub suture divides Peninsular Malaysia into a Sibumasu block on the west and an Indochina block on the east known locally as East Malaya.
Bentong raub suture sibumasu. Melange has a sheared mudsilt matrix. The Devonian and Carboniferous stratigraphy of the Malay Peninsula is discussed within a tectonic framework that includes a western Sibumasu Terrane and an eastern Sukhothai Arc Indochina block separated by the Bentong-Raub Suture Zone that. It forms the boundary between the Gondwana-derived Sibumasu terrane in the west and Sukhothai arc in the east.
The prominent NS Palaeo-Tethys Bentong-Raub suture divides Peninsular Malaysia into a Sibumasu block on the west and an Indochina block on the east known locally as East Malaya. The Bentong-Raub suture zone that divides them and the Semanggol Formation of northwest Peninsular Malaysia. It forms the boundary between the Gondwana-derived Sibumasu terrane in the west and Sukhothai Arc in the east.
After a gap comparable to the territory of Vietnam it reappears in the northern Malaysia and being recognized as Bentong-Raub suture. The suture zone is characterized by an imbricated complex resembling an accretionary prism of carbonaceous pelitic schist serpentinite amphibole schist mélange-olistostrome and chert as well as. BentongRaub Suture has a different pre-Jurassic tectonos-traigraphy and evolution to the Sibumasu terrane.
It is proposed that the BentongRaub Suture Zone represents a segment of the main Devonian to Middle Triassic Palaeo-Tethys ocean and forms the boundary between the Gondwana-derived Sibumasu. In partic-ular the Taku Schist of North-East. Modified after Metcalfe 2000.
The Palaeo-Tethys is represented by the Changning-Menglian Chiang MaiInthanon and Bentong-Raub suture zones. Conceptual cross-sections illustrating formation of the Bentong Raub Suture by subduction of the Palaeo-Tethys Ocean and collision of Sibumasu with the East Malaya Indochina terrane during the Indosinian Orogeny. Ad Top Quality at Half Price or Less.
The Bentong-Raub Suture is taken to be the result of northwards subduction of the Palaeotethys ocean beneath Indochina in the Late Palaeozoic and the Triassic collision and underthrusting of the Sibumasu Terrane with the Indochina-East Malay block Metcalfe 2000. The Bentong-Raub Suture Zone BRSZ of Peninsular Malaysia is one of the significant structural zones in Sundaland Southeast Asia. The Bentong-Raub Suture Zone BRSZ of Peninsular Malaysia is one of the major structural zones in Sundaland Southeast Asia.
The BRSZ is genetically related. Metcalfe 2013 and Hutchison 2009. The BentongRaub suture zone Ali et al 2016.
With this new discovery of a back arc basin of this suture system located within Vietnam the complete geographical location of the suture between the Indochina and Sibumasu block has been clearly verified and would be valuable information for geological studies. This suture represents the main Paleo-Tethys Ocean which was destroyed by collision of the Sibumasu and Indochina terranes of SE Asia. The Bentong-Raub Suture Zone BRSZ of Peninsular Malaysia is one of the major structural zones in Sundaland Southeast Asia.
It is proposed that the Bentong-Raub Suture Zone represents a segment of the main Devonian to Middle Triassic Palaeo-Tethys ocean and forms the boundary between the Gondwana-derived Sibumasu and Indochina terranes. Asia core Sundaland comprises a western Sibumasu block an eastern IndochinaEast Malaya block and the Sukhothai Island Arc terrane between. The Palaeo-Tethys is represented by the ChangningMenglian Chiang Mai-Chiang Rai Chanthaburi and BentongRaub Suture Zones that form the boundary between Sibumasu and the Sukhothai Arc.
Academiaedu is a platform for academics to share research papers. The BentongRaub Suture Zone represents the main Palaeo-Tethys Ocean which would have been at least 2000 km wide at some point during its history. Accordingly the area has been positioned as the suture connecting the Sibumasu and East Malaya BlockSukhothai Arc Metcalfe 2000.
This terrane is bounded to the northeast by the Song Ma Suture Zone. Western Central and Eastern Belt terminology after Khoo and Tan 1983. It forms the boundary between the Gondwana-derived Sibumasu terrane in the west and Sukhothai Arc in the east.
It was interpreted by Stauffer 1973 as part of an East Malaya Block but is now regarded as a southwards extension of the Indochina Terrane Metcalfe 1998. Bentong-Raub Suture Zone rocks include oceanic ribbon-bedded cherts argilllites turbitditic rhythmites serpentinites and continental marginshelf deposits olistostrom. The Jinghong Nan-Uttaradit and Sra Kaeo sutures represent the Sukhothai closed back-arc basin.
The Bentong-Raub suture zone forms the boundary between the Sibumasu Terrane Western Belt and Sukhothai Arc Central and Eastern Belts and preserves remnants of the Devonian-Permian main Palaeo-Tethys ocean basin destroyed by subduction beneath the Indochina BlockSukhothai Arc which produced the Permian-Triassic andesitic volcanism and I. The suture zone is characterized by an imbricated complex resembling an accretionary prism of carbonaceous pelitic schist serpentinite amphibole schist mélange-olistostrome and chert as well as undated post-suture redbeds. It is proposed that the BentongRaub Suture Zone represents a segment of the main Devonian to Middle Triassic Palaeo-Tethys ocean and forms the boundary between the Gondwana-derived Sibumasu and Indochina terranes.
The Indochina block was derived from Gondwana in the Devonian when the Palaeo-Tethys opened. Long lived subduction subsequently destroyed the Palaeo-Tethys beneath either Indochina Sibumasu or both resulting in destruction of the ocean and the eventual collision of these two continental lithospheric blocks.
