“…Scholarship in recent times has integrated major, trace, and rare earth elements in sediments for basin analysis studies to unravel the geochemical signatures of sedimentary succession using discriminatory diagrams (Dimalanta et al, 2018;Maravelis et al, 2021). However, this method appears to be faulty as it could not discriminate sediments from different geotectonic environments.…”

The marginal marine deposits signature is evident in the Permo-Triassic basins, the Sydney Basin is not an exception, and has not been subjected to source rock characterisation and petroleum system modelling designed at determining the potentials of hydrocarbon resources and its prospectivity. The economic potentials of the marginal marine environment are great, with enormous information in the literature that deals with the development of these deposits. The wide use of major, trace, and rare earth elements for basin analysis studies to unravel the geochemical signatures of sedimentary succession using the discriminatory diagrams fall short of addressing discriminate sediments from different geotectonic environments consequently a lag in source rock characterisation and petroleum system model of the marginal marine deposits. This review provides new insight into source rock, sediment supply, and depositional patterns of the marginal marine deposits in the Permo-Triassic Sydney Basin and its implication to the dearth in petroleum prospectivity.

“…Major, trace, and rare earth elements (REE) in sediments and sedimentary rocks have been applied to recent basin analysis studies for unravelling the geochemical signatures of the sedimentary successions (e.g., Armstrong‐Altrin, 2009; Dimalanta et al, 2018; Maravelis, Pantopoulos, Tserolas, & Zelilidis, 2015; Pantopoulos & Zelilidis, 2012). Several geochemical discrimination diagrams have been proposed to determine the provenance and tectonic setting of sedimentary basins (e.g., Bhatia, 1983; Condie, Noll Jr, & Conway, 1992; McLennan, Taylor, McCulloch, & Maynard, 1990; Roser & Korsch, 1986; Verma & Armstrong‐Altrin, 2013).…”

Provenance and tectonic setting of the Early Permian sedimentary succession in the southern edge of the Sydney Basin, eastern Australia

et al. 2020

Permian basins formed during a major phase of crustal extension are common throughout eastern Gondwana. One of these basins, the Sydney Basin, has not been subjected to geochemical studies aimed at determining the sedimentary provenance and the tectonic setting. This study provides new geochemical data of the Lower Permian siliciclastic successions in the southern edge of the Sydney Basin. Published petrographic analysis indicates a source area containing sedimentary, felsic volcanic, plutonic, and low-grade metamorphic rocks. Major, trace and rare earth element data suggest that the clastic rocks are geochemically mature and originated from a continental source that has been subjected to moderate to strong weathering. Further, they indicate that most source rocks were of felsic composition and that only the oldest sediments possess a more mafic signature. The provenance data presented in this study, along with published palaeocurrent data, point to the Lachlan orogen being the main source of sediments for the basin. Multi-dimensional discrimination diagrams suggest a continental rift setting and agree with the published sequence stratigraphic framework that suggests a deepening-upward depositional trend associated with tectonic subsidence. This study documents geochemically the provenance of the sedimentary successions within the southern edge of the Sydney Basin and the continental rift origin of the basin.

“…Sedimentary geochemistry techniques have proven their reliability in constraining sediment sources, tectonic setting, palaeoclimate and sedimentary processes in ancient terranes for palaeogeographic reconstructions (Bock et al , 1998; Hara et al , 2012; Dimalanta et al , 2017; Amedjoe et al , 2018). Provenance studies of sedimentary rocks can help decipher and determine the geodynamic evolution of the crust (Taylor and McLennan, 1981; Gromet et al , 1984; McLennan, 2001), juxtaposition of different tectonic terranes (Cutten et al , 2006; Gabo et al , 2009), tectonic setting of sedimentary basins (Bhatia, 1985; Bhatia and Crook, 1986; Roser and Korsch, 1986), emergence and unroofing histories of orogenic belts and island arcs (Roser et al , 2002), weathering processes and palaeoclimate responses in the source region (Nesbitt and Young, 1982; 1984; Nesbitt et al , 1996) and sediment sorting and recycling (Johnsson, 1993; McLennan et al ., 1993) among others.…”

“…Geochronological analysis of detrital zircons from the Lasala Formation (Mindoro Island) revealed bimodal U–Pb ages of 2,399 and 48 Ma, coincident with the Palaeoproterozoic and Yanshanian magmatism in mainland Asia. This led Dimalanta et al (2017) to conclude that the Palawan Microcontinental Block contains Cathaysian tectonic slivers. Likewise, studies conducted within the Philippine Mobile Belt include those of Tam et al (2005) and Dimalanta et al (2013) in the Baguio Mineral District in northern Luzon.…”

The Late Cretaceous Pandan Formation in Cebu Island is one of the oldest sedimentary units in the Central Philippines. The inconsistencies in geological descriptions and interpretation of the depositional environment of the Pandan Formation complicated efforts to determine the origin and tectonic history of the basement of Cebu Island. This study therefore looks into the petrological and geochemical characteristics of the Pandan Formation and their implications for the tectonic development of the Philippine Arc during the late Mesozoic. Petrographic analyses indicate significant contribution from mafic sources with additional inputs from felsic rocks, siliciclastics and metamorphic sources. Enrichment of detrital quartz from felsic volcanic and plutonic rocks, as well as from siliciclastic and metamorphic sources, has shifted the SiO 2 composition of the Pandan clastics from a mafic to a more intermediate source. Whole-rock geochemical analyses revealed low SiO 2 /Al 2 O 3 = 4.21, low K 2 O/Na 2 O = 1.16, low Th/Sc = 0.13, low Th/U = 2.78, high La/Th = 4.51, significantly low REEs = ca 76.45 ppm and low La N /Yb N = 4.28. A slight negative chondrite-normalized Eu/Eu* (0.91) anomaly and significantly high PAAS-normalized positive Eu/Eu* (1.39) values are consistent with derivation from a young undissected magmatic arc terrane. Tectonic discrimination diagrams suggest formation in an oceanic island arc to active margin/collision zone modelled to be located at the oceanic leading edge of Australia. Rapid uplift and erosion of the magmatic arc and older allochthonous blocks gave way to the rapid deposition of the Pandan Formation in the Late Cretaceous at the subequatorial region.
