“…A sea-level transgression marks the end of the Maastrichtian and maximum £ooding coincides with the K^T boundary clay layer (e.g. Donovan et al, 1988;Baum and Vail, 1988;Keller and Stinnesbeck, 1996;. The early Danian sea-level falls near the P0^Pla and Pla^Plb boundaries have been identi¢ed worldwide (MacLeod and Keller, 199la,b;Keller and Stinnesbeck, 1996).…”

“…The sea-level rise that began just below the K^T boundary reached a maximum in Zone P0 as suggested by condensed clay deposition worldwide (Brinkhuis and Zachariasse, 1988;Keller, 1988a,b;Donovan et al, 1988;Baum and Vail, 1988;Keller and Stinnesbeck, 1996;Stinnesbeck et al, 1996). The very low carbonate content in Zone P0 is likely related to the mass extinction of tropical and subtropical planktic foraminifera and calcareous nannofossils (Keller et al, 1995;Luciana, 2002;Pospichal, 1994).…”

Climate and sea-level fluctuations across the Cretaceous^Tertiary (K^T) transition in Tunisia were examined based on bulk rock and clay mineralogies, biostratigraphy and lithology in five sections (El Melah, El Kef, Elles, Ain Settara and Seldja) spanning from open marine to shallow inner neritic environments. Late Campanian to early Danian trends examined at El Kef and Elles indicate an increasingly more humid climate associated with sea-level fluctuations and increased detrital influx that culminates at the K^T transition. This long-term trend in increasing humidity and runoff in the Tethys region is associated with middle and high latitude cooling. Results of short-term changes across the K^T transition indicate a sea-level lowstand in the latest Maastrichtian about 25^100 ka below the K^T boundary with the regression marked by increased detrital influx at El Kef and Elles and a short hiatus at Ain Settara. A rising sea-level at the end of the Maastrichtian is expressed at Elles and El Kef by deposition of a foraminiferal packstone. A flooding surface and condensed sedimentation mark the K^T boundary clay which is rich in terrestrial organic matter. The P0P 1a transition is marked by a sea-level lowstand corresponding to a short hiatus at Ain Settara where most of P0 is missing and a period of non-deposition and erosion in the lower part of P1a (64.95 Ma). At Seldja, P0 and possibly the topmost part of CF1 are missing. These sea-level fluctuations are associated with maximum humidity. These data suggest that in Tunisia, long-term environmental stresses during the last 500 ka before the K^T boundary and continuing into the early Danian are primarily related to climate and sea-level fluctuations. Within this long-term climatic trend the pronounced warm and humid event within the latest Maastrichtian Zone CF1 may be linked to greenhouse conditions induced by Deccan volcanism. The absence of any significant clay mineral variations at or near the K^T boundary and Ir anomaly suggests that the bolide impact had a relatively incidental short-term effect on climate in the Tethys region.

“…Lowstand and forced regressive deposits are typically restricted or absent in such settings (Baum and Vail, 1988;Chakraborty and Paul, 2008). The rarity in identification of falling stage systems tracts always causes an incomplete stratigraphic record, only representing half of a sea level cycle (Chakraborty and Paul, 2008).…”

The present paper highlights the sequence development within the Mesoproterozoic Koldaha Shale Member of the Kheinjua Formation, Vindhyan Supergroup which records the occurrence of a forced regressive wedge and associated discontinuity surfaces at the base of the wedge. Nine lithofacies have been identified within the study area that are grouped into three lithofacies associations varying in depositional setting from outer shelf, through shorefaceforeshore-beach to continental braidplain. The outer shelf sediments are aggradational to slightly progradational representing highstand systems tract. The rapidly progradational, wedge-shaped shoreface to foreshore-beach succession occurs sharply or erosively above the outer shelf sediments and is bounded by a regressive surface of marine erosion (RSME) at the base and by a subaerial unconformity at the top. This, along with its downstepping trajectory, supports deposition of this sedimentary wedge during falling sea level. A laterally extensive soft sediment deformation zone occurs at the base of the wedge.The forced regressive wedge is incised by fluvial braidplain deposits that rest on an erosive surface representing a sequence boundary. The thin braidplain deposits are the product of aggradation during a subsequent early rise in relative sea level, and thus, they are inferred to represent a lowstand systems tract. The constituent architectural elements that characterize the braidplain deposits are downstream accretion elements and small channel elements. Further 1 landward, the base and top of the shoreface wedge merge to form an unconformity across deposits that rest directly on the outer shelf sediments. The identification of forced regressive wedges has significant economic importance in view of the potential occurrence of hydrocarbons within the Proterozoic formations.

“…The lithology and abundance of invertebrates that are often bound in calcareous matrix are common characteristics of the Tallahatta beds that overlie the Meridian Sand (Bybell and Gibson, 1985;Raymond et al, 1988). Overall, the Tallahatta is thought to represent a single third-order depositional sequence (sequence TE2.1 of Baum and Vail, 1988;Mancini and Tew, 1991), with the lower part of the unit consisting of nearshore and shallow marine deposits, and the upper half deeper, inner shelf deposits (Bybell and Gibson, 1985).…”
