Geology Of Sarawak Basin
University of Malaya The onshore North Sarawak Basin NSB comprises of three thick unconformity-bounded lithostratigraphic units each with its own sedimentological characteristics and structural style and history.
Geology of sarawak basin. Structurally SW Sarawak basin is a southward sloping basement characterized by passive margin tectonic that has undergone through varioius tectonic phases viz Triassic extension Cretaceous. The basin is situated in western Sarawak near the cost of the South China Sea. Regional structures and the predominantly Tertiary tectonics are described.
Ad Access articles from our new Remote sensing of Earth hazards Collection. The stratigraphical relationships between the formations have not been. Sedimentary successions in the Baram Delta consist mainly of alternating sandstones and siltstones with rare intercalations of mudstones.
The onshore North Sarawak Basin. Parameters of main types of overburden rocks and parameters of. The Sarawak Basin is an integral part of the NW Borneo Island that lies within the complex geological crustal mass of the SE Asia.
The paper briefly summarises the history of survey works and topographical geological stratigraphic and structural situation of coal basin. In Sarawak the mountains are constructed of Upper Cretaceous to Lower Eocene greenschist facies shaly turbiditic Rajang Group uplifted before the end of the Eocene. Hitherto the onshore segment of the Sarawak Basin is relatively unproductive in terms of hydrocarbon except for the onshore Baram Delta Province with three discoveries and two producing fields.
Currently open for submissions on a rolling basis. Several prominent workers from research institutions and from oil exploration companies have provided critical insight on the evolution of the Late Mesozoic to Tertiary aged South China Sea Basin. Structurally SW Sarawak basin is a southward sloping basement characterized by passive margin tectonic that has undergone through varioius tectonic phases viz Triassic extension Cretaceous transpression and Oligo-Miocene compression.
Academiaedu is a platform for academics to share research papers. The deep-water areas of the basin have not been extensively studied after the review by Madon in 1999 Madon 1999. Existing geological map ofSarawak Yin 1992 shows that the central part of Sarawak is occupied by several rock units the oldest being the Lupar Formation followed by the Belaga Formations and subsequently the Melinau Limestone Tatau Buan and Nyalau Formations.
The greatest coal basin of the state of Sarawak is the basin Mukah. Sarawak basin located in NW Borneo forms the southern margin of the Oligocene-Recent South China Sea Basin unconformably overlying the Rajang Group and the tectonic origin of this basin is still being debated. Zone A is a 7-8-km-thick Tertiary sedimentary basin in Sarawak deep water characterized by north-south-trending buried hills extensional fault-bounded features and local occurrences of compressional structures and is separated from the northwest Sabah platform zone B by a major north-south-trending basin margin fault.

The geology in Sarawak deepwater is closely associated and linked to the tectonic development of the South China Sea Basin. A geological and geophysical investigation of several key transects ofthe 1989 vintage seismic grid in the Sarawak deepwater was conducted in order to understand the sedimentation history and structural geology of the area. This study examines the petrophysical variations between these Middle to Upper Miocene sedimentary facies with emphasis on porosity permeability pore size distribution displacement pressure and irreducible water saturation.
