“…West Borneo is shown significantly rotated from its present position (Fig. 6), consistent with palaeomagnetic evidence (Fuller et al 1999), and rotation of the eastern tip of Sundaland to its early Cenozoic position is assumed to be related to collision of the East Java -West Sulawesi block.…”

Geology provides the basis for understanding distributions of faunas and floras in Southeast Asia but only via a complex interplay of plate movements, palaeogeography, ocean circulation and climate. Southeast Asia grew incrementally by the addition of continental fragments, mainly rifted from Australia, and added to the margins of Sundaland as a result of subduction. Sundaland was an almost permanent land area from the beginning of the Mesozoic. The addition of the continental fragments of Southwest Borneo and later East Java -West Sulawesi formed a much larger emergent land area by the Late Cretaceous that extended from Indochina to West Sulawesi. Subduction resumed at the Sundaland margin in the Eocene and this led to widespread rifting within Sundaland, and formed one of the most important barriers at its edge, the Makassar Straits. Australia began to collide with Southeast Asia about 25 million years ago, effectively closing the former deep ocean separating the two continents, and forming the region now known as Wallacea. Collision, volcanism, and subduction-related processes have led to rise of mountains but also formed new oceans within this complex region. Plate tectonic movements and collisions were intimately linked to changing topography, bathymetry and land/sea distributions which have in turn influenced oceanic circulation and climate. As the deep-water barrier between Australia and Southeast Asia was eliminated and mountains rose, deep marine basins also formed. Eustatic changes in sea level further contributed to a complex palaeogeography. The present gateway between the Pacific and Indian Oceans is the only low latitude oceanic passage between the world's oceans, and is an important influence on local and probably global climate. The gateway is likely to have been just as significant in the past. Understanding the geology, then palaeogeography, and then their oceanic and climatic consequences are vital steps on the way to interpreting present distributions of plants and animals.

“…1) reveal counter-clockwise (CCW) deflection in declination Fuller et al, 1999). Similar trend of declination has been observed in the Mesozoic and Cenozoic rocks of Borneo, South Sulawesi, Celebes Sea, and Peninsular Malaysia (Haile, 1978;Sasajima et al, 1980;Schmidtke et al, 1990;Shibuya et al, 1991;Richter et al, 1999;Fuller et al, 1999). This divergence in paleomagnetic declinations between northern and southern parts of Sundaland indicate an occurrence of internal tectonic deformation in this block, which can be taken as an important clue to understand the effects of deformation from two different collisional regimes (Australia vs.…”

“…9.5 Ma and collision of the Banda Arc with the Australian margin 8-3 Ma (Linthout et al, 1997); (2) regional uplift across the southeast Australian margin in the Late Miocene (Dickinson et al, 2000); and, (3) the apparent termination of tectonic rotation of terranes along the Australia-Philippine Sea plate margin (e.g. Fuller et al, 1999;Ali and Hall, 1995). The rate of northward drift we have calculated is faster than suggested in various tectonic models of Southeast Asia (e.g., Lee and Lawver, 1995).…”

Cenozoic northward drift of the Australian plate was determined from paleomagnetism of Middle Eocene through Pleistocene sediment cores from ODP Leg 182 (Sites 1126(Sites , 1128(Sites , and 1134 in the Great Australian Bight. Paleolatitude estimates are based on stepwise AF and thermal demagnetization of ∼400 discrete samples, of which ∼250 provided reliable data. The characteristic magnetization of the sediments resides in magnetite and magnetic sulfides. Middle Eocene through Lower Oligocene (∼36 Ma) paleolatitudes of ∼52• (±2 • ) change gradually to Late Miocene (∼9 Ma) paleolatitudes of ∼48• (±2 • ). These data, combined with Australian paleomagnetic pole data, indicate a slow rate of northward motion through much of the Cenozoic (∼28 mm/yr). These data also indicate an abrupt acceleration in the Late Miocene (drift rate ∼115 mm/yr), coinciding with tectonic events in Southeast Asia. Paleolatitude estimates support Miocene versions of the Australian apparent polar wander path that place the Oligocene-Miocene pole (∼25 Ma) at ∼70• S-125• E and the Late Miocene pole at ∼70 • S-105• E (e.g., Idnurm, 1985Idnurm, , 1994. Inclination data for discrete samples also provide a refined magnetostratigraphy for portions of the Miocene, Oligocene, and Eocene carbonate and siliciclastic section of the Great Australian Bight.
