WebIreton formations. These variations may be related to fluid content and pore pressure difference between the Duvernay and Ireton formations (Dvorkin, 2000). Analysis of directional anisotropy in rock properties based on the log data showed little directionality in the plane of bedding, but the lab data showed WebThe Camrose Member of the Ireton Formation, and the Nisku Formation (Frasnian) of the subsurface of the Bashaw area, Alberta represent episodes of shallow water carbonate …
WebIn the Woodbend Group of central Alberta, shales of the Ireton Formation occupy the basinal areas between the Leduc reefs. Within the shales are thin limestone beds which can be traced as electric-log markers over large areas. These markers probably approximate time lines, and they show a distinct westward divergence from the Ireton-Nisku contact. WebMay 14, 2024 · For example, reef formation is not resumed after the Ireton Clay deposition in the Western Canada basin, and reefs are missing in the Nisku carbonate formation that terminated the Frasnian Stage. CONCLUSIONS. The Earth’s Paleozoic history includes five stages of framework reef formation: Early Cambrian, Middle–Late Ordovician, Silurian ...
WebThe inter-reef Ireton Formation of the Upper Devonian Woodbend Group of Alberta is essentially a calcareous shale with variable amounts of inter-bedded nodular limestones. … WebMay 1, 1997 · In general, replacement dolomites are composed of fabric-destructive, fine to medium (60-250 mu m) planar subhedral to anhedral crystals. Replacement dolomitization postdates submarine cementation and deposition of shales and carbonates from the overlying Ireton Formation, and overlaps stylolitization.
The Winterburn Group is conformably overlain by the Wabamun Group and overlays the Ireton Formation, except in the Peace River Arch, where it rests on the Precambrian basement. It is correlated with the Birdbear Formation and part of the Three Forks Group in Saskatchewan, with the Southesk Formation and Alexo Formation in the Canadian Rockies and with the Redknife Formation and Kakisa Formation in north-eastern British Columbia.
WebThe Woodbend group of Upper Devonian age in central Alberta is composed of a reef complex characterized by large-scale facies changes. The reefs, which grew in a subsiding basin, were initiated in restricted areas of suitable water depth. They are surrounded by the calcareous shales and argillaceous limestones of the Duvernay and Ireton formations. churchill 2021 tv showWebIreton Formation Thickness up to 150 metres (490 ft)[1] Lithology Primary dolomite, limestone, siltstone Other Anhydrite, shale Location Coordinates 53°20′42″N113°41′42″W / 53.3451°N 113.6949°W / 53.3451; -113.6949 (Winterburn Group)Coordinates: 53°20′42″N113°41′42″W / 53.3451°N 113.6949°W / 53.3451; -113.6949 Region … devil\u0027s brood sharon kay penmanWebIreton synonyms, Ireton pronunciation, Ireton translation, English dictionary definition of Ireton. n Henry. 1611–51, English Parliamentarian general in the Civil War; son-in-law of … devil\u0027s chair beerWebJun 1, 2011 · Oil and gas are trapped at two stratigraphic levels, the Leduc-aged Bashaw Reef Complex (D-3) and the Camrose Member–Nisku Formation (D-2), which are separated by a low-permeability aquitard of the Ireton Formation, a marl … devil\\u0027s chainsaw mandevil\u0027s cave red dead 2Ireton Formation: Frasnian: upper: calcareous shale and argillaceous limestone middle: fissile grey-green shale with calcirudite beds lower: massive and banded limestone with shale partings: 250 m (820 ft) Cooking Lake Formation: Frasnian: limestone: fossiliferous mudstone and wackestone, grainstone, … See more The Woodbend Group is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin.
