“…The initial wrench faulting may have started before the deposition of the Bau limestones, presumably outside the investigated area. Radiometric dates of granites in the Malaya Peninsula (see Burton & Bignell, 1969) also imply that there the youngest possible period of active faulting agrees with that in Sarawak. Fitch (1963) has suggested that a general northward movement of the core of Borneo/Kalimantan explains the synclinal and structural development of the Upper Cretaceous-Tertiary rocks in northern Borneo.…”

SummaryGeological discontinuities, lineaments, field observations, and interpreted π-girdles demonstrate a left lateral, NNW trending transcurrent fault in the Sarawak-kiri valley of West Sarawak. Topography and geology also suggest that the fault belongs to an important fracture zone that extends well into Indonesian Kalimantan, and continues in a northerly direction along the edge of the Sunda Shelf beneath the South China Sea.Comparison with transcurrent faulting occuring in the Malay Peninsula and a probable wrench fault between Palawan island and Sabah (North Borneo) reveals the continental part of southeast Asia to have rotated counter-clockwise up to Lower Palaeogene time, probably as a response to spreading of the Pacific ocean floor.

“…peak, Late Cretaceous. Similar conflicts between K-Ar and whole-rock Rb-Sr ages were found in less extensive dating studies in Malaya by Rodger E. Denison (written commun., 1972) and in peninsular Thailand by Burton and Bignell (1969). The whole-rock ages also conflict with the limited separate-mineral Rb-Sr work done by Bignell and Snelling.…”

“…Thai granites have been an interesting topic for researchers who have worked in this region for many decades (e.g., Brown et al, 1951;Aranyakanon, 1961;Pitakpaivan, 1969;Burton and Bignell, 1969;Baum et al, 1970;Garson et al, 1975;Pitfield, 1988;Charusiri, 1989). There are three N-S-orientec.…”

The N-S oriented central floodplain of Thailand is situated between the NE-SW-trending strike-slip Uttaradit Fault Zone (UTFZ) to the north, the northern shoreline of the Gulf of Thailand to the south, and irregular paths of normal faults to the east and west. Major structures of the area include the NW-SE-trending sinistral strike-slip Mae Ping and Three Pagoda Fault Zones (MPFZ and TPFZ) located to the west and a N-S-oriented Central Volcanic Belt (CVE) located to the east of the plain. Tertiary basins located within the Central Plain have geometries indicating that they were formed due to the reversed movement from sinistral to dextral ofthe major NW-SE-trending strike-slip fault zones during Late Oligocene-Early Miocene times. Geophysical data interpretation results (magnetic, gamma-radiometric, digital terrain data and regional gravity data) show the N-S-trending CVE, outline the known major fault zones, discover the Chao Phraya Fault Zone (CPFZ) and other subsurface lineaments and magnetic bodies within the Central Plain, as well as suggest a new fault path for the TPFZ. The findings indicate that the tectonic evolution of the Central Plain was controlled by the movement along the CVE, which may represent an ancient suture zone, and strike-slip faults bounding small subcontinental blocks. These movements include: extension (oblique) along the old sutures and volcanic arcs, reversed sinistral-to-dextral movement on the NW-SE-trending MPFZ, TPFZ and CPFZ, and reversed dextral-to-sinistral UTFZ. Indochina's southeast extrusion tectonic setting associated with the collision of the Indian and Eurasian plates may have reactivated these lithospheric weak zones and caused the opening of the Central Plain and the Gulf of Thailand since Late Oligocene time.
