Gradient analysis of faunal distributions associated with rapid transgression and low accommodation space in a Late Pennsylvanian marine embayment: Biofacies of the Ames Member (Glenshaw Formation, Conemaugh Group) in the northern Appalachian Basin, USA

Sequence stratigraphy, sedimentary systems and petroleum plays in a low-accommodation basin: Middle to upper members of the Lower Jurassic Sangonghe Formation, Central Junggar Basin, Northwestern China

“…Unconformity surfaces and incised channels may have developed at the margins of lakes at the same time as fining-upward successions of coarse-grained sandstone and conglomerate and carbonaceous mudstone were being deposited in the basin. The architecture of strata in a non-marine subsiding basin may be characterized by fluvial-to shallow-lake environments in low-accommodation settings, as reported in several studies of stratigraphical sequences (Aschoff and Steel, 2011;Chalmers et al, 2013;Hildred et al, 2010;Lebold and Kammer, 2006;Nadon and Kelly, 2004). However, questions concerning the internal architecture of these low-accommodation sequences remain unresolved.…”

“…No subaqueous fans of the deep lake were deposited in the basin during the LST. The LST2 developed in low-accommodation conditions (sensu Aschoff and Steel, 2011;Chalmers et al, 2013;Hildred et al, 2010;Lebold and Kammer, 2006).…”

Examining Local Climate Variability in the Late Pennsylvanian Through Paleosols: An Example from the Lower Conemaugh Group of Southeastern Ohio, USA

“…The Appalachian basin during the Middle to Late Pennsylvanian was located in the tropics at a paleolatitude of approximately 5-10° S [13][14][15]. During this time the Appalachian basin was flanked on the northwest by the Cincinnatian Arch and on the southeast by the Appalachian Highlands [15].…”

“…The Appalachian basin during the Middle to Late Pennsylvanian was located in the tropics at a paleolatitude of approximately 5-10° S [13][14][15]. During this time the Appalachian basin was flanked on the northwest by the Cincinnatian Arch and on the southeast by the Appalachian Highlands [15]. Deposition in the Appalachian basin was controlled by glacio-eustatic sea level fluctuations and tectonics as well as changing climatic conditions which caused shifting deltaic environments responsible for the thick sandstone deposits found throughout the basin [1,[16][17][18][19][20].…”

Late Tournaisian (Carboniferous) brachiopods from Mouydir (Central Sahara, Algeria)

“…Moreover, the smooth spiriferid genus Crurithyris is generally considered as an opportunistic eurytopic taxon characteristic of stressful and/ or dysaerobic environments (e.g. Kammer et al, 1986;Lebold and Kammer, 2006;Campi and Shi, 2007).…”
