“…The oldest parts of the sequences that formed in the basins may be Paleocene (e.g. van Leeuwen 1981;van de Weerd et al 1987;Wain & Berod 1989;Kusuma & Darin 1989;Satyana et al 1999;Fraser & Ichram 2000) but this is very uncertain because the oldest parts of the sequences are typically terrestrial and poorly dated. By the Middle Eocene, extension was well underway and Eocene rocks are interpreted as syn-rift deposits of extensional graben and half-graben.…”

The Lariang and Karama regions of western Sulawesi, an area of approximately 10 000 km 2 , were the subject of a field-based investigation with the aim of understanding the Cenozoic evolution of the North Makassar Basin. Western Sulawesi was influenced by the development of the Makassar Straits to the west and the collision of continental, ophiolitic and island-arc fragments to the east. The timing of these events has been the subject of considerable debate and it has been suggested that Neogene collisions in Sulawesi caused inversion in Borneo. A new stratigraphy for the Lariang and Karama regions of western Sulawesi, based on fieldwork, provides new and significant insights into the evolution of the Makassar Straits region. The oldest sediments are non-marine and could be as old as Paleocene; they include coals, sandstones and mudstones. Rifting had started by the Middle Eocene and continued into the Late Eocene. Syn-rift Eocene sediments were deposited in graben and half-graben in both marine and marginal marine environments. The Eocene Makassar Straits rift was highly asymmetrical; the Kalimantan margin was approximately twice the width of the Sulawesi margin. Thermal subsidence had started by the latest Eocene and by the end of the Oligocene most of western Sulawesi was an area of post-rift shelf carbonate and mudstone deposition. This shallow-marine depositional environment persisted throughout the Early Miocene and, in places, until the Middle or Late Miocene. In the Pliocene the character of sedimentation changed significantly. Uplift and erosion was followed by the deposition of coarse clastics derived from an orogenic belt to the east of the study area. The Palaeogene half-graben were inverted, there was localized detachment folding and the overlying Neogene section was folded, faulted and eroded in places. Contractional deformation in western Sulawesi dates from the Pliocene, whereas in eastern Kalimantan it dates from the Early Miocene.

“…This caused the severing of the land connection between Kalimantan and Sulawesi (Wilson and Moss, 1999), which in turn ruptured the supply of siliciclastic material to SW Sulawesi (Fraser and Ichram, 2000). Carbonate development (Tonasa Formation), that had began locally during the Middle Eocene (Harahap et al, 1999), became widespread in SW Sulawesi during the Late Eocene forming a 100 km by 40-50 km platform area (Wilson and Bosence, 1996;Wilson et al, 2000).…”

“…In SW Sulawesi, terrestrial to marginal marine siliciclastics of the Malawa Formation were deposited (t' Hoen and Ziegler, 1917;Sukamto, 1982), possibly in a series of fault-bounded sub-basins. The siliciclastic material was probably derived from the Sundaland continental basement (Hamilton, 1979;Fraser and Ichram, 2000). The clastic supply was from time to time interrupted, allowing peat deposits to be formed, which are preserved in the stratigraphic record as thin coal beds (t' Hoen and Ziegler, 1917).…”

“…According to Hamilton (1979), there is an ocean-spreading centre that extends along the Makassar Strait, interpreted on the basis of several NW-SE trending faults. Fraser & Ichram (2000) also assumed oceanic crust to be present under the northern and southern parts of the Makassar Strait, while Cloke (1997) argued that oceanic crust was present only under the northern part of the strait. The Makassar Strait has also been interpreted as a remaining ocean basin (Malecek et al, 1993) or as a back-arc basin (Parkinson, 1998).…”

Palaeofacies and biomarker characteristics of Paleogene to Neogene rocks in the Makassar Straits, Indonesia

Borehole K-1 is an exploratory well that was drilled in the North Makassar Basin (West Sulawesi) in 2011. Gas chromatography (GC) and gas chromatography-mass chromatography (GC-MS) analyses have been conducted on extracts from well cuttings from the Paleogene to Neogene interval in order to investigate the characteristics of biomarkers present. Although the well was drilled with oil-based mud and gas chromatographic analysis reveals that the alkane fractions are heavily contaminated, detailed investigation of biomarkers in these rock extracts and comparison with biomarkers in the oil-based mud has revealed that, while there are hopane and sterane biomarkers in the mud, there are also a discrete set of biomarkers that are indigenous to the rocks. These include oleanane, bicadinanes, taraxastane and other higher-plant-derived triterpanes. The presence of these compounds in environments that range from bathyal to marginal marine and even to lacustrine, shows the extent of reworking of terrestrial material into aquatic settings in this region during the Paleogene and Neogene and provides further evidence of a predominance of terrestrial material, even in deep-marine settings, with little ‘in-situ’ material noted. These findings have important implications for the use of biomarkers as indicators of palaeoenvironment in both source rocks and oils.
