The Southeast Sulu Sea is a small oceanic basin that opened in Middle Miocene time in a back-arc setting along the Sundaland margin during subduction of the Celebes Sea plate beneath the Sulu arc. The western trench system is where the marginal basins (South China Sea, Sulu Sea and the Celebes Sea) of the Eurasian Plate are subducting (Rangin & Pubellier 1990; Ringenbach et al. lb). (noun) The area of each basin ranges from 36,000 sq km to 92,000 sq km (Sulu Sea is bigger but it is partly covered by oceanic crust). The Sulu Trench marks the boundary of the Sulu micro-block with the Sulu Sea basin and the Palawan micro-block. RESEARCH PROJECTS BROWSE BY LOCATION Sulu Sea Basin Projects. “According to the Philippine Department of Energy, the offshore Sulu Sea Basin has a potential 203 MMBOE, while the land-based Cotabato Basin has a potential 159 MMBOE with 29 BCF of gas already discovered,” Mastura said. The three petroleum play types identified in the basin are carbonate reef build-ups, anticlines and fault blocks.

The basin extends to the north-east portion of Sabah in Borneo where there have been gas discoveries, another indication of … Better sources and more sophisticated processing yielded better and deeper resolution of the data. The opening and closure (when Australia‐Eurasia eventually collide) of these basins represent the final tectonic episode of the Neo‐Tethys, an ocean that separates the northern and southern continents. 1). The 40,000 sq km basin contains as much as 8,000 m of Neogene deltaic May 10th, 1993 across the deep basin of Sulu–Celebes Sea could introduce. We compare new/published geochronological and geochemical data from across the circum‐Sulu Sea region, and summarize seven major magmatic phases from the Middle Eocene to Pleistocene.

The Sandakan Sub-basin, located in the southern Sulu Sea Basin (Figure 1), is different from other parts of the region and different from most basins within the Philippines. Since the Sulu Sea is a closed basin below 420m (Kuehl et al 1993), the temperature of the deep water is uniformly near 10 C, (Tizard et al 1884) the phosphate is about 3 microgram-atoms/litre while the nitrate level is 35 microgram-atoms/litre. Physics, Comets and Geology and Geophysics, Physical errors [50]. Introduction Figure 1:Configuration and bathymetry of the Sulawesi Sea (m). The reprocessing project was conducted in association with MultiClient Geophysical (MCG). Two wells drilled in the slope-basinal area encountered turbiditic sands towards the bottom part of the wells. establishing a regional geologic framework This back-arc extension post-dates compressive tectonism present in this back arc area in early Middle Miocene time. Objects, Solid Surface The subduction may have formed arc magmatism (21–18 Ma) in the Cagayan ridge and its continuation in Panay and NE Sabah, and opened the NW Sulu Sea backarc basin through continental crust attenuation. Unlimited viewing of the article PDF and any associated supplements and figures. The use of the technique by government and academic groups helped solve basc structural and evolutionary problems of rocks of the deeper offshrore. The results indicate that the Sulu Basin originated in the late early Miocene (c. 18.8 Ma) in a backarc setting. According to the magnetics model, it is likely that the Sulu Sea Basin started to open at 30-35 Ma (early Oligocene) with 0.6 cm/yr half-spreading rate.

The Cenozoic Sulu Sea arc‐basin system is situated in the tectonic junction between the South China Sea (SCS), northern Borneo, Palawan Continental Terrane, Philippine Mobile Belt, and Celebes Sea. in Modeling Earth Systems (JAMES), Journal of Geophysical Research The four companies that submitted bids were Israel’s Ratio Petroleum Ltd. (Area 3-East Palawan Basin); Sulu Sea Energy Resources Development Corp. (Area 6-Sulu Sea Basin); the partnership of The Philodrill Corp. and PXP Energy Corp. (Area 7-Sulu Sea Basin); and Esmaulana Global Ventures Company, Inc. (Area 6-Sulu Sea Basin). Starting of final convergence between the Palawan Continental Terrane and northern Borneo‐SW Philippines (∼21 Ma) likely caused regional uplift/thrusting, forming the Top Crocker Unconformity and triggering the NW‐dipping Celebes Sea subduction. GEOLOGICAL OUTLINES The Sulu Sea is a structurally complex basin, elongated in a northeast-southwest direction. One well even had oil and gas shows in MDT samples. Planets, Magnetospheric Thus, the estimated generation time for IWs are. The Sulu Sea is an example of a marginal sea with two distinct basins of different types: (1) the Outer Sulu Sea basin, formed inside an old island arc, the Palawan arc; (2) the Inner Sulu Sea, a basin with an oceanic crust. In the central Philippines, convergence of the Eurasian Plate with the PMB is expressed as a continent (Palawan Microcontinental Block)-arc collision zone. There are 32 chapters divided into the following sections: Rifted Margins; Convergent Margins; Small Basin Margins; and Resources, Comparative Structure, and Eustatic Changes in Sea Level.

Geophysics, Marine The Sulu Sea basin consists of the Sandakan sub-basin while the East Palawan basin is divided into the Balabac and Bancauan sub-basins. Processes in Geophysics, Atmospheric southeast Sulu Sea basin crust subducts along the Sulu Trench and the Negros Trench, with the northern termi-nation of the latter lying west of Panay. Exploration efforts in Sulu Sea Basin draw a significant attention to turbidites, an emerging petroleum play in the deeper parts of the basin. “These petroleum reserves calculations are based on the 16 sedimentary basins situated all over the country from the Cagayan Valley Basin in the north down to the Agusan-Davao Basin in the south as well as the prolific Northwest Palawan Basin and the Sulu Sea Basin along the western flank of the archipelago,” the DOE said. The Sulu Sea basin may have continued to expand till ∼9 Ma, when NW‐dipping subduction of the Celebes Sea stopped. Southeast Asia is located at the junction of four plates: the Eurasian, Indian Ocean/Australian, Pacific, and Philippine Sea plates.

Please check your email for instructions on resetting your password. After the SCS opening (∼32 Ma) and ridge jump (∼25 Ma), late‐stage Proto‐SCS subduction (24–21 Ma) may have formed the Panay arc andesite and the BABB magmatism in SW Zamboanga peninsula. "The Sulu Sea: A Marginal Basin in Southeast Asia", Geological and Geophysical Investigations of Continental Margins, Joel S. Watkins, Lucien Montadert, Patricia Wood Dickerson. Data incorporated in this analysis includes 2D seismic, gamma-ray logs, biostratigraphy and cuttings NW‐dipping Celebes Sea subduction largely ceased after ∼9 Ma, followed by extension‐related uplift/exhumation and 4–0.2 Ma intraplate volcanism in northern Borneo. Northern Borneo underwent intraplate extension and magmatism after ∼9 Ma, and the Sulu Sea subducted along Sulu‐Negros trench from ∼4 Ma. and Chemical Oceanography, Physical Sulawesi Sea is linked with the Sulu Sea through a … By continuing to use our website, you are agreeing to our, Cushman Foundation for Foraminiferal Research, Mineralogical Society of Great Britain and Ireland. When and how these sea basins were created are long disputed. Similar Borneo basins including the Baram Delta, the North Sabah Basin, the Tarakan Basin, and the Kutei Basin have combined reserves of greater than 10 billion bbls of oil and 35 tcf of gas. Small Bodies, Solar Systems The Sulu Sea Basin, by contrast, is a delta superimposed on a back-arc basin where expected play types are carbonate reef build-ups, anticlines and fault blocks. Their interaction during Tertiary times resulted in a complex active margin composed of a mosaic of small geotectonic units such as microcontinental blocks, island arcs, and marginal seas. MMBOE stands for million barrels of oil equivalent. It is fringed to the southeast and the east by an active margin, supposedly the remains of a larger active margin which during Tertiary times extended along the western side of the Philippines from Luzon to Negros and perhaps from the Sulu Archipelago to the northeastern part of Sabah. From the Middle Eocene to Early Miocene the Sandakan Sub-basin was affected by the opening of the South China Sea. Knowledge of continental margins advanced rapidly during the 1970s. Geophysics, Biological After Palawan Continental Terrane accretion, Sulu Sea backarc basin was opened by Celebes Sea subduction (∼21 Ma) and rollback (17–9 Ma). Basin Fill and Structure The Sulu Sea Basin is one of 14 depocenters in the Philippine Archipelago, a collage of island arcs, continental fragments and tectono-stratigraphic terranes of various origins. The Sulu Sea and the adjacent sea basins (e.g., Celebes and SCS) are situated at the junction between the Eurasian, Philippine Sea, and Indo‐Australian plates. All-Filipino firm Sulu Sea Energy Resources Development Corp. (SSERDC) is eyeing a contract for an offshore area within the Sulu Sea basin (PDA No. It is 650 km long and 400 km wide, located between the South China Sea to the north and the Celebes Sea to the south (Fig. This sub-basin, an element of the Sulu Sea Basin, has been the interest of several exploration efforts in Malaysia and Philippines, but there is still no production activity in the area. It contains up to 6 km of primarily Miocene to Pliocene deltaic and deepwater sediments. Processes, Information The Sulu Sea is an example of a marginal sea with two distinct basins of different types: (1) the Outer Sulu Sea basin, formed inside an old island arc, the Palawan arc; (2) the Inner Sulu Sea, a basin with an oceanic crust. A garment similar to a sarong, worn by Melanesians, as in the Fiji Islands. Accepted, unedited articles published online and citable. If you do not receive an email within 10 minutes, your email address may not be registered, To better disseminate new knowledge of continental margins, AAPG held three meetings in 1977 to review the current status of knowledge. Spreading continued until at least 10 Ma (early upper Miocene). 1). Subduction rollback likely occurred in 17–14 Ma and 13–9 Ma, shifting arc magmatism southeast to the Sulu ridge and opening the SE Sulu Sea backarc basin. Most of the oceanic crust is already subducted. Use the link below to share a full-text version of this article with your friends and colleagues. Recent mag-matic activity related to the Negros trench subduction is however absent from the island, whereas it is well-developed in the neighboring island of Negros (Sajona et al., 2000).

The Sandakan basin lies in the southwestern Sulu Sea straddling the Philippines/Malaysia maritime border (Fig. Please cite this article as doi: 10.1029/2020TC006630. Our model suggests that the Sulu Sea was formed by the NW‐dipping Celebes Sea subduction at ∼21 Ma, in response to the collision between the South China‐derived Palawan Continental Terrane and northern Borneo‐SW Philippines. The Sulu Sea basin extends to the northeast portion of Sabah where there have been gas discoveries. Composition and Structure, Atmospheric The final edited and typeset version of record will appear in the future. SE‐dipping Sulu Sea subduction likely occurred along the Negros‐Sulu trenches, and produced arc volcanism from ∼4 Ma. Geophysics, Mathematical Sulu Sea Basin Projects. The basin has high potential but is under-explored. The papers presented at those meetings are contained in this volume. What does sulu mean?
