Big IV Borneo

Bibliography of Indonesian GeologyBIBLIOGRAPHY OF THE GEOLOGY OF INDONESIA AND SURROUNDING AREAS 4th Edition, November 2011 J.T. VAN GORSEL IV. BORNEO www.vangorselslist.com IV. BORNEO This chapter of the bibliography contains about 1580 titles on the Borneo region, about 935 of which are from the Indonesian side of Borneo island (Kalimantan). It is subdivided in three chapters: IV.1. Borneo General, Kalimantan, Mahakam Delta IV.2. North Borneo (Sarawak, Sabah, Brunei) IV.3. Makassar Straits. The island of Borneo is subdivided among three countries, Indonesian Kalimantan in the South and Brunei and East Malaysia (Sarawak and Sabah) in the North. Although the absence of present-day major earthquakes and active volcanism makes it look like a relatively stable block, its Cretaceous- Miocene history is one of great tectonic activity.

Borneo (General, Kalimantan, Mahakam Delta) Borneo consists of a core of Paleozoic or older continental crust metamorphic rocks in the SW part of the island. The 'traditional' interpretation has been that SW Kalimantan is part of the 'Sundaland' complex of Gondwana-derived plates (together with South China, Indochina, East Malaya) that had been part of Eurasia since the Permian-Triassic (e.g. Metcalfe 1987). More recently it was proposed to be a separate microplate that broke off the NW Australia margin as late as Jurassic ('Argoland'; Hall et al. 2009, Metcalfe 2010). This requires that the NW part of Kalimantan is a separate microplate (Semitau Block of Metcalfe (2010), because its Late Carboniferous- Jurassic faunas clearly belong in the 'Cathaysian' realm, not Gondwana. Debate on this will undoubtedly continue. Paleomagnetic data suggest SW Borneo has been near the equator at least since the Jurassic, and rotated counterclockwise by about 90° since the Jurassic, a bout 50° since the Cretaceous. These results have b een consistent between three separate academic groups and are therefore rather compelling. The SW Borneo continental terrane is intruded by a belt of late Early Cretaceous Schwaner Mts granite batholiths (~100-130 Ma; Williams et al. 1989), which are the exhumed deeper parts of a volcanic arc that formed above a South-dipping subduction of the 'Proto-China Sea' oceanic plate. Younger arc volcanics include a Late Cretaceous (Campanian; ~75-80 Ma) belt of smaller granite plutons in the Kalimantan- Sarawak border area and possible multiple Tertiary belts, like the Middle Eocene Nyaan Volcanics. The youngest and best-defined belt is the Late Oligocene- Early Miocene (~30-16 Ma) Sintang Intrusives belt, which is associated with several gold mines. The North side of the SW Borneo continental core is a series of Cretaceous-Miocene accretionary complexes. The oldest of these is the (Late Jurassic?-) Early Cretaceous melange of radiolarian cherts, red siliceous shales and ultrabasic rocks ('Danau Fm' of Molengraaff, 1910), also called Semitau/ Selangkai/ Boyan Melange, Kapuas Complex, Telen- Kelinjau melange, etc.) (see also next chapter on N Borneo). This old melange belt may continue East as far as the Mangkalihat Peninsula (often portrayed as a microcontinental block, but nearest Pre-Tertiary outcrops and well penetrations look more like 'Danau melange'). N-S cross-section Semitau area, NW Kalimantan (Molengraaf 1902). N-S cross-section Sarawak-N Kalimantan border area (Molengraaff 1902). Showing from left: intensely deformed 'Old Slate Fm' of U Kapuas Mts (2), folded Mesozoic Danau Fm (3), unconformably overlain by Cretaceous claystone (12a) and Tertiary sandstone Fm (16), overlain by young volcanics (32). The Meratus Mountains in SE Kalimantan, with its outcrops of melange and serpentinites and associated oceanic crust rocks, have long been regarded as a suture zone between colliding continental blocks at the SE edge of Sundaland. There is indeed ample evidence of mid-Cretaceous age (~90 Ma) ophiolite obduction, with a blueschist-grade metamorphic sole, but the ophiolite sheet is nearly flat and it is not clear (1) whether the subduction zone was NW or SE dipping, and (2) what collided here. The present relief of the Meratus Bibliography of Indonesia Geology v.4.0 2 www.vangorselslist.com Nov. 2011 The Kutai Basin of E Kalimantan probably has the thickest sediment fill (12-14 km) of all Indonesian basins.

Significant angular unconformities have been reported from the Kutai and Tarakan basins in the late Middle Eocene and around the Early. 2009) and somehow must have come from a Gondwanan terrane. The Melawi Basin is probably older than the Ketungau Basin. Eocene and Oligo-Miocene carbonates are present in all E Kalimantan basins. mainly in a marine environment. but. but are uneconomic.1 Ga.. This suggests the age of subducted oceanic crust was at least partly older than M Jurassic ('Meso-Tethys' oceanic plate?).

They are all in alluvial deposits and their origin is unknown. representing the ages of the pelagic cover scraped off during subduction. The Schwaner Mountains granite plutons formed at >6 km depth. 2011 . Some of this uplift was early. A series of papers have speculated on their origin. and does not necessarily parallel Cretaceous basement grain. Part of the accommodation was tied to extension during the M Eocene and younger rifting of the Makassar Straits. Heryanto (1991) interpreted these as forearc basins between N-migrating uplifted accretionary prisms. The Tanjung field in the Barito basin is one of the few fields producing from Late Eocene sandstones. Ophiolite obduction in the Meratus Mountains was followed by a period of Late Cretaceous arc volcanism.Middle Miocene boundary (Achmad and Samuel 1984. Finally. probably mainly in the Early Tertiary.4. Moss 1998). but parts have to be older.
