... as allochthonous terranes throughout the area, one of the most far traveled examples being the island of Buton, southeast of Sulawesi. Asphalt reserves on Buton support a significant local industry and exploration continues for oil and natural gas. In common with other prospective Australian-derived terranes...

...RANDALL B. SMITH; ELI A. SILVER Abstract The island of Buton in eastern Indonesia is part of a Neogene collision zone that encompasses much of the eastern margin of Sulawesi. Miocene collision of microcontinents with a west-dipping subduction zone emplaced the Tukang Besi platform (TBP) against...

... are probably underlain by oceanic rust. A poorly understood ridge, the Buton-Tukang Besi block, protrudes SE from Sulawesi nto the Banda Sea. This may be a micro-continent (Hamilton 1978). 0016-7649/79/090045 19$02.00 @ 1979 The Geological Society 5 20 M. S . Norvick L E G E N D Active Quaternary volcanoes 0...

... the Neogene (probably Miocene) of Buton Island, Indonesia. There it is recorded as being “rare to very common” in “ Globigerina marl and limestone with asphalt seepages, impregnations and veins” ( Keyzer, 1953 , p. 261, 268), consistent with a probable association with fossil methane seeps ( Kvenvolden...

... and Buton ( Hall and Sevastjanova 2012 ; Metcalfe 2017 ), which are bounded by a complex system of strike-slip, normal and thrust faults ( Sukamto 1975 ; Hamilton 1979 ; Silver et al. 1983 ; Hall 2002 ; Beaudouin et al. 2003 ; Bellier et al. 2006 ; Watkinson 2011 ).

... be subdivided into six major tectonic units, namely the northern Sulawesi arc, central Sulawesi metamorphic belt, West (or western) Sulawesi, eastern Sulawesi ophiolites, and Banggai-Sula and Tukang Besi-Buton microcontinents ( Fig. 2 ). The northern Sulawesi arc, consisting mainly of Cenozoic island arc...

...-Buton ( Fig. 2 ; e.g., Maulana et al., 2016a ; Zhang et al., 2020 ). Continental basement rocks of West Sulawesi are exposed as metamorphic complexes in several localities, including the Malino, Palu, Latimojong, Barru, Bantimala, and Biru areas ( Fig. 2 ). Although these metamorphic complexes do...

... ). The diamictites are younger than the U–Pb zircon date of 598.1 ± 6.0 Ma from basalts in the lower part of the described succession ( Maslov et al., 2013 ). The succession of Tany, Garevka, Koiva and Buton Formations of the Serebryanaya Group constitutes the Laplandian Glacial Regional Stage of the western...

... large areas, probably the result of a plate readjustment. Three separate collisions of microcontinents with Sulawesi have been described: Buton ( Davidson, 1991 ), Banggai-Sula (Garrard et al., 1988; Simandjuntak, 1987 ), and Tukan Besi ( Davidson, 1991 ) (see Figure 1 ). These blocks originated from...

A post-war report by BPM (Bataafsche Petroleum Maatschappij, the principal Dutch-Shell company in Indonesia) considered the region to be the second most prospective in Sulawesi after Buton. This paper presents an integrated summary of the geology of the Lariang...

... blocks onshore and offshore eastern Sulawesi were offered by Pertamina in mid year. Three of these had been awarded by year end: the Buton block to Conoco, the Sula block to Britoil (its first operatorship in Indonesia), and the Manui block to Amoseas. The remaining block, Tukang Besi, had not been...
