The continental shelf along northeastern Australia is the world's largest mixed carbonate-siliciclastic passive margin and location of Great Barrier Reef (GBR). Following sea-level transgression during last deglaciation, extensive sediment was deposited GBR due to neritic carbonate deposition (including edge reefs, Holocene reefs Halimeda bioherms) fluvial discharge terrigenous siliciclastic se...

Suspended sediments produced from dredging activities, or added to the sediment budget via river runoff, are a concern for marine resource managers. Understanding the impact of suspended sediments on critical life history stages of keystone species like corals is fundamental to effective management of coastlines and reefs. Coral embryos (Acropora tenuis and A. millepora) and larvae (A. tenuis, ...

ABSTRACT The presence of archaeocyath-bearing clasts from Cenozoic tills and Cambrian Mount Wegener Formation reveal erosion a hidden carbonate platform in Shackleton Range, Antarctica. We provide microfacies, paleontological, diagenetic tectonically induced fabric data which, addition to available geochemical geochronological allow the paleoenvironmental reconstruction lost Series 2 mixed sili...

A sedimentological and stratigraphic study of Low Isles Reef off northern Queensland, Australia was carried out to improve understanding of factors that have governed Late Holocene carbonate deposition and reef development on the inner to middle shelf of the northern Great Barrier Reef. Low Isles Reef is one of 46 low wooded island-reefs unique to the northern Great Barrier Reef, which are situ...

The Tirgan Formation (Barremian – Aptian) is exposed in the Kopet Dagh in northeast Iran. One stratigraphic section in Zavin was measured with a thickness of 110 meters. This Formation in section consists of three parts (including lower carbonate, limy shale – marl and upper carbonate rocks). Based on the study of 94 thin sections, 10 carbonate and 2 siliciclastic lithofacies have been identifi...

Carbonate contourite drifts are poorly documented in the onshore record because of difficulty implementing diagnostic criteria for their recognition. Accordingly, little is known about relative position carbonate with respect to ancient platforms, seaways and shallow passages within context palaeoceanography. This study presents a fossil example mixed carbonate-siliciclastic drift cropping out ...

pore pressureis defined as the pressure of the fluid inside the pore space of the formation, which is also known as the formation pressure. when the pore pressure is higher than hydrostatic pressure, it is referred to as overpressure. knowledge of this pressure is essential for cost-effective drilling, safe well planning, and efficient reservoir modeling. the main objective of this study is to ...
