“…High frequency, high amplitude sea‐level changes during the Aptian are therefore frequently interpreted to be glacio‐eustatic in nature, triggered by the growth and decay of polar ice sheets (e.g. Miller et al ., , ; Bover‐Arnal et al ., , ; van Buchem et al ., ; Donnadieu et al ., ; Husinec et al ., ; Maurer et al ., ; Peropadre et al ., ; Millán et al ., ; Ladant & Donnadieu, ). These glacio‐eustatic interpretations are supported by an ever‐growing body of evidence corroborating Early Cretaceous ‘cold snaps’ and polar glaciation events (Fig.…”

The impact of Aptian glacio‐eustasy on the stratigraphic architecture of the Athabasca Oil Sands, Alberta, Canada

High-frequency incised valley systems and subaerial exposure surfaces are prevalent in Aptian-aged units, having been documented in numerous basins around the world. In light of a growing body of palynological, geochemical and sedimentological evidence, a glacio-eustatic mechanism for their generation has been suggested, driven by the waxing and waning of polar ice caps. The densely-penetrated McMurray Formation of north-eastern Alberta, Canada, provides a unique opportunity to test for an Aptian glacio-eustatic signal within the Western Canadian Foreland Basin. This study combines detailed drill core description with wireline log-based stratigraphic analysis to map and evaluate a series of drainage networks located along the cratonic edge of the Western Canadian Foreland Basin. Four stratigraphically distinct composite channel-form bodies are documented across an area >14 000 km 2 . Composite channel-form bodies are up to 50 km wide and locally exceed 70 m thick, subtending from upward-coarsening parasequence sets 2 to 12 m thick; bounding marine flooding surfaces are mappable over distances exceeding 280 km along the north-south trending basin. Detailed internal fill characterization of the four composite channel-form bodies suggests that three represent tidal-fluvial incised valley networks, and one represents a deltaic distributary system. At least six cycles of transgression and regression are apparent within the McMurray Formation stratigraphy. Recent biostratigraphic assessment has constrained deposition of the McMurray Formation between ca 125 Ma and 118 Ma, and periods on the order of 0Á7 to 1Á7 Ma are estimated for the mapped transgressive-regressive cycles. The high frequency nature of these Aptian sequences suggests that the sea-level oscillations recorded in McMurray Formation strata are consistent with a glacioeustatic driver. Linking the internal stratigraphic architecture of the McMurray Formation with interpreted global cooling events and sea-level drops provides the first evidence of glacio-eustasy within Early Cretaceous strata of western Canada.

“…Given that the timing of these cooling phases fits well with the late Early and Late Aptian periods of reduced accommodation recognized in several basins worldwide, a glacio‐eustatic mechanism is commonly favoured (e.g. Gréselle & Pittet, ; Bover‐Arnal et al ., ; van Buchem et al ., ; Maurer et al ., , ; Raven et al ., ; Husinec et al ., ; Rameil et al ., ).…”

Deep incision in an Aptian carbonate succession indicates major sea‐level fall in the Cretaceous

Long-term relative sea-level cycles (0Á5 to 6 Myr) have yet to be fully understood for the Cretaceous. During the Aptian, in the northern Maestrat Basin (Eastern Iberian Peninsula), fault-controlled subsidence created depositional space, but eustasy governed changes in depositional trends. Relative sea-level history was reconstructed by sequence stratigraphic analysis. Two forced regressive stages of relative sea-level were recognized within three depositional sequences. The first stage is late Early Aptian age (intra Dufrenoyia furcata Zone) and is characterized by foreshore to upper shoreface sedimentary wedges, which occur detached from a highstand carbonate platform, and were deposited above basin marls. The amplitude of relative sea-level drop was in the order of tens of metres, with a duration of <1 Myr. The second stage of relative sea-level fall occurred within the Late Aptian and is recorded by an incised valley that, when restored to its pre-contractional attitude, was >2 km wide and cut ≥115 m down into the underlying Aptian succession. With the subsequent transgression, the incision was back-filled with peritidal to shallow subtidal deposits. The changes in depositional trends, lithofacies evolution and geometric relation of the stratigraphic units characterized are similar to those observed in coeval rocks within the Maestrat Basin, as well as in other correlative basins elsewhere. The pace and magnitude of the two relative sea-level drops identified fall within the glacio-eustatic domain. In the Maestrat Basin, terrestrial palynological studies provide evidence that the late Early and Late Aptian climate was cooler than the earliest part of the Early Aptian and the Albian Stage, which were characterized by warmer environmental conditions. The outcrops documented here are significant because they preserve the results of Aptian long-term sea-level trends that are often only recognizable on larger scales (i.e. seismic) such as for the Arabian Plate.

“…Cretaceous age have recently been considered to have had, at least partly, a eustatic-climatic origin (e.g.,Matthews and Frohlich, 2002;Gréselle and Pittet, 2005; Bover-Arnal et al, 2009, 2014Maurer et al, 2010Maurer et al, , 2013Raven et al, 2010;van Buchem et al, 2010; Boulila et al, 2011;Husinec et al, 2012;Rameil et al, 2012). In this respect, late Early Aptian cooling trends associated with biotic changes have been documented in the Maestrat Basin (e.g., Solé de Porta andSalas, 1994; Pascual-Cebrian, 2014; Cors et al, 2015) as well as in other basins of the Tethys (e.g.,Weissert and Lini, 1991;Hochuli et al, 1999;Steuber et al, 2005;Skelton and Gili, 2012; Bottini et al, 2014).…”
