Aspects of the Neogene tectonic history and hydrocarbon geology of the Tarakan basin

Transverse segmentation of the Baram-Balabac Basin, NW Borneo: refining the model of Borneo's tectonic evolution

“…The C-D boundary can be projected into the Semporna Fault Zone on the NE of the Tarakan Basin (Lentini & Darman 1996) or possibly the Sibuda Fault of Balaguru & Hall (2008). This boundary coincides with a zone interpreted as separating areas with an opposed sense of post-Miocene shear (Ingram et al 2004).…”

Petroleum systems of Indonesia

“…The Tarakan Basin has a similar development to the Kutei-Mahakam Basin (Lentini and Darman, 1996), which it resembles in many ways (Fig. 13).…”

Tertiary stratigraphy and basin evolution, southern Sabah (Malaysian Borneo)

“…Hinz and Schlüter (1985) and Fulthorpe and Schlanger (1989) also recognised this change in depositional environment in offshore NW Sabah. Further south in Kalminatan, carbonate sedimentation occurred during this time in the Tarakan Basin (Lentini and Darman, 1996) and the Kutai Basin (Moss et al, 1997). In eastern Sabah the Gomantong Limestone outcrops in a ENE -WSW-trending belt stretching at least 200 km, which suggests that this may have been a zone of uplift along which localised carbonate sedimentation occurred, isolated from any clastic sediment influx from the west.…”

“…The Labang Formation, which is exposed in southern Sabah, therefore represents deposition of deep-water clastics in a fore-arc basin setting from the Late Eocene through to the Late Oligocene. During the Oligocene there was widespread regional subsidence across eastern and northeastern Kalimantan (Lentini and Darman, 1996;Moss et al, 1997;Moss and Chambers, 1999) which would have extended into Sabah. Outcrops of Labang Formation typically show abundant syn-depositional and syn-diagenetic extensional faults that suggest active growth faulting associated with this subsidence.…”
