“…They are then unconformably overlaid by the Pliocene Tarakan conglomerates, during the subsequent paleo-Simengaris Delta progradation. Those Tarakan conglomerates barely occupy the eastern coastal strip, suggesting a substantial erosion occurred on Nunukan Island after the deposition of Tarakan Formation, as have been pointed out in other part of Tarakan Basin by existing seismic data (Akuanbatin et al, 1984;Wight et al, 1992;Noon et al, 2003;Rosary et al, 2014).…”

“…The responsible tectonic inversion was taken place in Plio-Pleistocene, corresponding with the formation of Tarakan arches, including Ahus Arch in Tidung sub-basin (Akuanbatin et al, 1984;Wight et al, 1992;Lentini and Darman, 1996;Noon et al, 2003;Rosary et al, 2014). Vitrinite reflectance, porosity and seismic data suggest 1000-1500 m of structural inversion occurred during arch formation (Lentini and Darman, 1996).…”

Nunukan Island is located in Northeast Kalimantan Basin, one of proliﬁc basin in western Indonesia. However, this island lies in northern verge of the basin and hydrocarbon exploration were limited before the 1940s. No detail geological ﬁeldworks has been published. This paper attempts to share geological information obtained from few accessible outcrops, particularly from the western part of the island where previous oil drilling were carried out. Most of the island have been built by Tabul Formation, which was also the main objective of reservoir for hydrocarbon exploration. It is composed of claystones, siltstones, and sandstones interbeds, deposited in transitional environment during Late Miocene. They exhibit coarsening upward sequence, the lower part composed of heterolitic sandstones deposited in tidal ﬂats, and the upper part composed of arkosic sandstones deposited in distributary channels and mouthbars. The eastern coastal strip was constructed by Tarakan conglomerates, which have been deposited in ﬂuvio-deltaic environment in Pliocene, unconformably over the Tabul clastics. Those Neogene deposition of paleo-Simengaris Delta apparently deformed and inverted in Plio-Pleistocene, contemporaneously with basaltic volcanism which spread widely over northeastern Borneo, which also observed in the northern half of the Nunukan Island

“…In this paper, cleats are divided (Nelson, 1983;Laubach et al, 1998) into two basic types: face cleats (linear discontinuities that developed perpendicular to the bedding plane) and butt cleats (perpendicular to the bedding plane and oriented at nearly 90 o to the face cleats).

Coal seams of lignite-to subbituminous rank of Pliocene-age from the Sajau Formation of the Berau Basin are characterized by the presence of a natural fracture system, including cleats. Often, these opening-mode fractures consist of two orthogonal sets (face and butt cleats), both almost perpendicular to the bedding. This paper describes the distribution of orientation, spacing, and aperture of cleats formed in the seams of the Sajau Formation. All observations and measurements were conducted at macroscopic, mesoscopic, and microscopic scales. The butt cleat mean orientations are NE-SW and NW-SE, whereas the face cleat mean orientations are NNE-SSW and NE-SE, and the cleat dip is at a high angle of 75° to the north. The angles between the orientations of these cleat sets are nearly 90°; that is, they are orthogonal. The spacing of the macroface cleats is between 9.52 and 14.46 cm (averaging 11.61 cm), while the spacing of the butt cleats is between 2.3 and 11.3 cm (averaging 5.35 cm). The mean aperture is 0.54 mm. In contrast, the mean spacing of the mesoface cleats is 3.09 mm, and the aperture measurements of these cleats range from 0.0478 to 0.0741 mm (averaging 0.0549 mm). The results obtained from outcrops and X-ray CT (computed tomography) scan clearly indicate that the NNE-SSW face cleat orientations are strictly parallel to the elongation of the main tectonic structures in the studied area. Their origin may be explained by their relationship with local tectonic stress (the maximum principal stress, σ1, was horizontal). Partial least square analysis of data collected from cleats and faults in the area indicates that a power law distribution exists between the cleat characteristics (spacing, density, and aperture), and the distance of the faults (R 2 = 0.56). Cleat formation in the Sajau Formation was mainly controlled by the mechanical response to tectonic stresses, which generated a unique cleat network in the coal. Based on the SEM photography, it is concluded that the development of microcleats in the Sajau Formation resulted from both endogenic processes and tectonic activities as indicated by the change in the shape of the cleats, from straight line to curved shape and branching (intersection of multiple cleats that form a conical network at the end).

“…Poorly exposed lignite and carbonaceous mudstones cropping out on the northeast Mangkalihat Peninsula are most likely Middle to Late Eocene in age based on palynology (Wilson and Evans, 2002;Noon et al, 2003). However, a mixed carbonatesiliciclastic succession closely associated with the lignites may vary in age from Late Eocene to Late Oligocene and organic-rich units may range into the Oligocene.…”

“…However, a mixed carbonatesiliciclastic succession closely associated with the lignites may vary in age from Late Eocene to Late Oligocene and organic-rich units may range into the Oligocene. The Mangkalihat lignites contain humic, oil and gas prone kerogen that could be precursor oil and gas prone source rocks (Noon et al, 2003).…”
