A review of Permian–Carboniferous glacial deposits in Western Australia

Sedimentary imprints of former ice-sheet margins: Insights from an end-Ordovician archive (SW Libya)

“…The stars indicate the importance of each structure for the identification of ice-margin settings (i.e., one star: low significance; two stars: good significance; three stars: strong significance). Mory et al, 2008;Rocha-Campos et al, 2008), endOrdovician Ghienne, 2004, 2005;Clark-Lowes, 2005;Denis et al, 2007a) and Neoproterozoic (Deynoux, 1985;Vernhet et al, 2012) successions. Based on the end-Ordovician record in the Djado area (Niger), Denis et al (2010) proposed a comprehensive deformation model where cyclic modifications of fluid pressure at the ice/bed interface resulted in small-to meso-scale subglacial shear deformation structures formed at the top, and within a subglacial sediment pile, both constituting the shear zone.…”

A latest Carboniferous warming spike recorded by a fusulinid-rich bioherm in Timor Leste: Implications for East Gondwana deglaciation

“…1), and (2) the southward increasingly more restricted conditions within the interior sea. If the presence of warm-water faunal elements within the Asselian or uppermost Pennsylvanian in Timor was confirmed, correlation could be made with the known rapid increase in sedimentation derived from melting ice in the west Australian basins (Mory et al, 2008). More detailed analysis of the Timor fauna, may also determine if its stratigraphic level coincides with the Gzhelian maxima for late Paleozoic tropical fusulinid diversity (Groves and Lee 2008;) and thus a potential global warming episode (Mayhew et al, 2012).…”

“…Within the East Gondwana rift system, lowest Permian and uppermost Carboniferous deposits are known from Timor in the north (about 40° S) and can be traced to the south through the Bonaparte, Canning, Carnarvon, and Perth Basins (about 60° S) with decreasing marine influence ( Fig. 1; Charlton et al, 2002;Gorter et al, 2005;Hocking et al, 1987;Mory and Beere, 1988;Mory et al, 2008;Playford et al, 1976). The Timor succession has been affected by Neogene orogeny (Keep and Haig, 2010;Audley-Charles, 2011;Haig, 2012), whereas the west Australian basins remain relatively undeformed.…”

Glaciogenic reservoirs and hydrocarbon systems: an introduction

“…This large intracratonic rift and sag basin contains thick sequences of glaciofluvial and glaciodeltaic sandstones, together with subaqueous fans and tunnel valley deposits, which form the main reservoir facies (Redfern & Williams 2002;Mory et al 2008). Traps are structural and stratigraphic, in some case developed by post-Permian inversion along pre-existing faults.…”
