“…The main phase of basalt volcanism took place in the Late Barremian to Early Aptian, upper Isachsen Formation (ca. 127-115 Ma) mainly on Axel Heiberg Island (Embry & Osadetz, 1988 (Evenchick et al, 2015), as well as volcaniclastic sandstones (Embry & Osadetz, 1988), and bentonite layers (Schröder-Adams et al, 2014) on Axel Heiberg Island.…”

The poorly studied Alpha-Mendeleev Ridge of the Amerasia Basin of the Arctic Ocean is covered by a large magnetic high and interpreted to be part of the Cretaceous High Arctic Large Igneous Province (HALIP). At the north coast of Ellesmere Island, in the Yelverton Bay area, this characteristic magnetic high overlaps the shelf and the coastal area. Results of aeromagnetic surveys, geological fieldwork, geochronological, geochemical and Sr-Nd isotope analysis were combined to study the tectonic history of this part of the Canadian Polar margin. The basement, consisting of metamorphic rocks of the Pearya Terrane, was strongly affected by HALIP-related magmatism that is responsible for characteristic positive magnetic anomaly patterns. A broad magnetic high that can be traced to the Alpha Ridge covers the shelf and coastal areas of Yelverton Bay. It is caused by a voluminous intrusion into the continental crust at a depth of ca. 6-15 km. A chain of small positive magnetic anomalies crosses Wootton Peninsula from SW to NE and then curves into a NNE-SSW trend. It follows the coastline onshore and offshore and superimposes the southern and eastern margins of the broad magnetic high. On land, the anomaly chain covers fault-bounded outcrops of the Wootton Intrusive Complex (WIC) and the Hansen Point Volcanic Complex (HPVC), indicating that the entire anomaly chain is associated with a volcanogenic sequence. Rhyodacite that forms large parts of the HPVC east and west of Yelverton Bay extruded between c. 104 and 97 Ma (LA-ICP-MS U-Pb zircon ages). It originates from a tholeiitc suite and is probably genetically related to the deep intrusion. The HPVC together with the rhyodacite has an age range of c. 104-74 Ma and includes the mildly alkaline WIC (93-92 Ma). The northern coast of Ellesmere Island shows some characteristic features of a magma-rich rifted margin indicating an extensional evolution parallel to the North American margin between the openings of the Canada Basin and the Eurasian Basin.

“…The breccia must be younger than the dated 105.4 ± 0.2 Ma pyroclastic rocks at the top of the Invincible Point Member. It must be older than the Albian-Cenomanian boundary (100.5 Ma) based on uppermost Albian fossils at the top of Christopher Formation and in the lower Hassel Formation (Galloway et al, 2012, and references therein;Schröder-Adams et al, 2014;Pugh et al, 2014;Fig. 12).…”

Field evidence, map compilation, geochemistry, geochronology, and potential fi eld data document six intervals of Cretaceous magmatism in the central Sverdrup Basin. These are: (1) Hauterivian (ca. 130 Ma) volcaniclastic deposition in the lower Isachsen Formation; (2) 126.6 ± 1.2 Ma (U-Pb zircon) gabbroic intrusion; (3) 120.8 ± 0.8 Ma (U-Pb baddeleyite) diabasic intrusion; (4) 105.40 ± 0.22 Ma (U-Pb detrital zircon) pyroclastic deposition at the top of the Invincible Point Member, Christopher Formation; (5) upper Albian (ca. 103 Ma) pillow and hydroclastic breccia in the upper Christopher Formation; and (6) uppermost Albian (ca. 101 Ma) volcanic breccia and scoria in the Hassel Formation.Whole-rock geochemical data show that these magmatic rocks are similar to previously documented High Arctic large igneous province tholeiitic basalts, but analyses of fresh glass in tuffs reveal evolved ferroandesite to dacite compositions not recorded in whole-rock data. Approximate ages of saucer-shaped sills inferred from the relationship of sill width to depth of emplacement suggest at least three intervals of sill emplacement between 130 and 120 Ma. The new data show that volcanism in the Sverdrup Basin was of greater spatial extent, and that magmatism occurred more frequently, than was previously recognized. Comparison of the new central Sverdrup Basin data and interpretations with other data sets from the Sverdrup Basin, Svalbard, and Franz Josef Land suggests that High Arctic large igneous province magmatism occurred over a more extended period of time in the central Sverdrup Basin than in other regions.

“…Depositional cycle 5 is characterised by a backstepping gamma ray signature and positive spikes in the sonic log. These depositional cycles are later linked to largescale transgressive/regressive cycles that are observed basin-wide Schröder-Adams et al, 2014) and globally (Gradstein et al, 2012).…”

“…Sliter (1981) pointed out that G. tailleuri alone reaches down into the Late Jurassic (Ramsay, 1970;Souaya, 1976), but the entire assemblage zone is assigned to the Early Albian. Schröder-Adams et al (2014) studied the Aptian/Albian Christopher Formation on Axel Heiberg Island and assigned the Quadrimorphina albertensis Zone to the Aptian part of this formation (Figure 26). On the Peel Plateau the Q. albertensis Zone was defined for the lower Albian interval (Thomson et al, 2011).…”

Cretaceous (Albian to Cenomanian) Strata of Eagle Plain, Yukon: Subsurface Foraminiferal Biostratigraphy, Regional Correlations and Paleoenvironments

The Eagle Plain, located in the northeastern Yukon Territory, Canada, forms a northern segment of the Cretaceous Western Interior Sea. Its preserved mid-Cretaceous strata document an active structural regime with sea-level fluctuations and changing sediment supply areas. The mid-Cretaceous rocks are unconformably underlain by either Paleozoic or younger Mesozoic formations. Recent paleontological evidence, including pollen, foraminifera and macrofossils from outcrop sections in the Eagle Plain, suggested that Albian to Cenomanian aged strata are preserved. This package includes the Whitestone River, Parkin, Fishing Branch, Burnthill Creek and Cody Creek formations. This project tests new subsurface stratigraphy hypotheses by examining two continuous cores (Molar P-34 and Ellen C-24) and their benthic foraminiferal assemblages. It compares subsurface faunal changes with those obtained from outcrop samples by Haggart et al (2013) and integrates those to well log signatures that are used to establish the subsurface architecture. Three new biostratigraphic zones are recognized; the Early Albian Gaudryina tailleuri Zone in the lower Whitestone River Formation, the Middle to early Late Albian Gaudryina canadensis Zone in the Upper Whitestone River and sandstone member of the Parkin Formation, and the latest Albian Miliammina manitobensis Zone in the shale member of the Parkin Formation and lowermost Fishing Branch Formation. The biostratigraphic framework established in the subsurface correlates well with the fauna observed in outcrops. Foraminiferal assemblages are almost entirely dominated in both cores by agglutinated specimens that document a response to regionally recognized fluctuating sea-level changes during the Albian. Observations of foraminiferal morphogroups and their relative proportions allow for iii paleoenvironmental reconstruction, including oxygen and nutrient conditions. The Ellen C-24 well represents a fully marine, well oxygenated proximal shelf deposited during the lower to early Late Albian Whitestone River Formation. The Molar P-34 well represents a deep water, offshore setting with increased accommodation space marked by sediment slumping, demonstrating a northwestward deepening of the basin. This interpretation is supported by the presence of abundant tubular suspension feeders which are less common in the Ellen C-24 well. In both settings a marked lithological change from mudstone to sandstone occurs between the Whitestone River and Parkin formations, corresponding to a distinct faunal changeover from rich to impoverished fauna. The Whitestone River Formation documents Albian sea-level fluctuations of the Moosebar, Hulcross, Joli Fou and Mowry seas. These are distinguished from each other by faunal reductions that mark regressive phases and shifts in log signatures, and can be correlated to the northern Polar Sea and southern Western Interior Sea basins, as well as globally. The latest Albian disconformity is believed to occur in the terrestrial sandstones of the Fishing Branch Formation. Whi...
