Bentong raub suture sibumasu. The BRSZ is genetically related to the sediment-hostedorogenic gold. The Indochina block was derived from Gondwana in the Devonian when the Palaeo-Tethys opened. The Bentong-Raub Suture Zone BRSZ of Peninsular Malaysia is one of the significant structural zones in Sundaland Southeast Asia.

The Sibumasu block subsequently collided with the Sukhothai Arc in the Triassic forming a suture zone referred to as the Chiang Rai Line also known. 1 represents a segment of the main Devonian to Middle Triassic Palaeo-Tethys ocean and forms the boundary between the Gondwanaland-derived Sibumasu and Indochina terranes. Accordingly the area has been positioned as the suture connecting the Sibumasu and East Malaya BlockSukhothai Arc Metcalfe 2000.

Western Central and Eastern Belt terminology after Khoo and Tan 1983. The Bentong-Raub Suture Zone BRSZ of Peninsular Malaysia is one of the major structural zones in Sundaland Southeast Asia. Radiolarians recovered from rocks within the Bentong Raub Suture Zone sensu stricto Figs.

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 Bentong-Raub Suture Zone BRSZ of Peninsular Malaysia is one of the major structural zones in Sundaland Southeast Asia. It is a southwards extension of the Nan-Uttaradit and Sra Kaeo sutures of Thailand.

The Indochina block was derived from Gondwana in the Devonian when the Palaeo-Tethys opened. Bentong-Raub Suture Zone is considered as a collision zone between the Sibumasu and East Malaya Indochina terranes. Hence the structural setting of the Mae Sariang Group is.

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. 1 and 5 suggest that an open ocean basin existed between the Sibumasu and Indochina terranes from at least Late Devonian to Middle Permian indicating that opening of the Palaeo-Tethys occurred in the Devonian as advocated by Metcalfe 1996 1997. It forms the boundary between the Gondwana-derived Sibumasu terrane in the west and Sukhothai arc in the east.

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 BentongRaub suture zone Ali et al 2016. Bulletin of the Geological Society of Malaysia.

The prominent NS Palaeo-Tethys Bentong-Raub suture divides Peninsular Malaysia into a Sibumasu block on the west and an Indochina block on. Major deformational phases in Peninsular Malaysia Systematic regional structural geology analyses for Peninsular Malaysia are generally lacking. The BentongRaub Suture Zone includes accretionary complex rocks with oceanic ribbon-bedded cherts argillites turbiditic rhythmites mélange serpentinites and continental marginshelf deposits.

The Bentong-Raub Suture Zone Fig. It forms the boundary between the Gondwana-derived Sibumasu terrane in the west and Sukhothai Arc in the east. Forms part of the Sibumasu continental lithospheric terrane Other occurrences of Carboniferous Permian and Trias- Metcalfe 1984 1986 1988.

Sibumasu Terrane Central Belt extends eastwards beneath the Central Peninsular Malaysia west of the BentongRaub Suture Belt or has been displaced eastwards by faulting. 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. 41 after Metcalfe 2000b.

The Bentong Raub Suture Zone Metcalfe I. East Malaya was attached to the Indochina plate. The Bentong-Raub suture is believed to signify the remnant of the Paleo-Tethys ocean subduction beneath the Indochina-East Malaya terrane which was terminated in the late Middle Triassic.

The prominent NS Palaeo-Tethys Bentong-Raub suture divides Peninsular Malaysia into a Sibumasu block on the west and an Indochina block. The Bentong-Raub suture zone that divides them and the Semanggol Formation of northwest Peninsular Malaysia. 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.

Metcalfe 2013 and Hutchison 2009. Palaeo-Tethyan oceanic ribbon-bedded cherts in the suture zone range in age from Middle Devonian to Middle Permian and mClange includes Lower. 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.

The main occurrences of the suture zone rocks are shown in Fig. In partic-ular the Taku Schist of North-East Peninsular Malaysia as depicted inFigure 1b is notable. 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.

Abstract 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 suture zone is characterized by an imbricated c. It forms the boundary between the Gondwana-derived Sibumasu terrane in the west and Sukhothai Arc in the east.

Sibumasu was a part of the Cimmerian plate which was attached to Gondwana during the Carboniferous. While in Northern Thailand the Mae Sariang Group lies on the west side of the Doi Inthanon metamorphic complex this Sibumasu basement region is about 100 km wide and the main PalaeoTethys suture CMCRSZ equivalent to the Bentong-Raub suture lies about 50 km east of the metamorphic complex.
