“…Concerning PCA analysis, it was found that the two principal components (PC 1 and 2), which control 80.75% of compositional data variation (Table 4), are mainly correlated with sandstone and black chert clast abundances (Table 5). The bi-plot of the two main principal components recognized by PCA analysis (Nielsen et al, 2015;Von Eynatten et al, 2003) indicated that there is a difference in clast abundance between outcrops 2, 5 and 9 (orange ellipse) in relation to the outcrops 1, 3, 4, 6 and 8 (black ellipse) and outcrops 7, 10, 11 and 12 (blue ellipse) (Figure 14a). Cluster analysis also identified three main outcrop groups based on clast lithologies (Figure 14b).…”

Provenance and statistical analysis of the Lower Oligocene gravelly deposits in central Pindos foreland basin, western Greece: Implications for orogenic build‐up and unroofing

This study integrates provenance and statistical data, along with published sedimentological results, applied on the Lower Oligocene submarine‐fan deposits in Pindos foreland basin. Twelve outcrops were analysed using conglomerate clast composition, petrographic and statistical analysis and this integration suggests that the studied deposits were sourced by the Pindos Orogen. Conglomerate clast composition analysis suggests that the studied deposits contain mainly limestone clasts, followed by sandstone and chert clasts. This conclusion is further supported by the petrographic and cathodoluminescence analyses that have been conducted on the conglomerate matrix and, additionally, suggest the influence of a low‐grade metamorphic source. Potential source rock candidates in the Pindos Orogen that provided the detritus in the succession are represented by the Mesozoic carbonates (limestone and chert), the Cenozoic transitional (mixed carbonate and siliciclastic) and the Cenozoic clastic submarine‐fan deposits (sandstone). The rock units of Pelagonian zone likely represent the low‐grade metamorphic source rock. The principal component and cluster analysis of clast lithologies suggest the existence of three compositional clusters, with the first one being controlled by black chert clasts, the second one by sandstone clasts and the third one by limestone and red chert clasts. The upward increase of chert and lithic fragment abundances is ascribed to the progressive unroofing of the Pindos orogenic source regions. This study utilizes the Pindos foreland basin as an example to unravel the contribution of orogenic processes on sedimentary provenance of the adjacent pro‐foreland basins. Furthermore, this study highlights the advantage of implementing a multi‐faceted approach, including statistical treatment in sedimentary provenance.

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.

“…It should be noted however, that except for the Amalie-1 well, no Lower Cretaceous reservoir-quality sandstones are found. Yet a few localised sandy apron or lobe units may have developed as a continuation of the Jurassic deep marine sandstones in the area (Bonde et al 1994;Nielsen et al 2015). Similar deposits could also have developed in the Gertrud Graben and Feda Graben to the South and SW of the exposed Mandal High (Rossland et al 2013), but there is currently no evidence to support this interpretation and identifying such reservoirs, if present, will be highly challenging.…”

Lower Cretaceous reservoir development in the North Sea Central Graben, and potential analogue settings in the Southern Permian Basin and South Viking Graben

Much of the future hydrocarbon exploration potential in the North Sea lies in locating stratigraphic traps and discrete reservoir intervals. This study assesses the potential for Lower Cretaceous reservoirs, with particular focus on the Norwegian Central Graben and proposed methods to identify future prospects over a wider area. Seismic interpretation and well data reveal the structure and sedimentology of the study area. Although the region was isolated from a large hinterland in the Early Cretaceous, potential local sediment sources, sediment transport routes and areas with possible reservoir development are identified. The greater Mandal High area, where Lower Cretaceous shoreface deposits and submarine fan systems are postulated, is suggested for primary focus. Similar deposits may have developed around the other exposed highs in the region, although several were drowned towards the end of the Early Cretaceous. Detailed seismic and stratigraphic analysis will be necessary to identify individual reservoir units. Since similar settings may have occurred in the adjacent South Viking Graben and Southern Permian Basin regions during the Early Cretaceous, further reservoir assessment is recommended for the North Sea in general.
