3D PGF Model v1

3D Provincial Geological Framework Model of Alberta, Version 1 (dataset, multiple files)

Abstract: Version 1 of the 3D Provincial Geological Framework model has been superseded by version 2. The 3D Provincial Geological Framework Model of Alberta, Version 1 (3D PGF model) covers 602 825 square kilometres of the province and excludes an area representing the approximate extent of Cordilleran deformation.  The model was deconstructed and Zip format packages of digital data available for download include; a tab-delimited tabular dataset of stratigraphic picks and point data used to create the model a deconstructed model dataset composed of either:  a set of discrete and continuous model horizons as Esri format grids and zone model shapefiles, or   an Esri geodatabase, and an iMOD model dataset package. Methods used to create the model and more information about these data are described in AGS Open File Report 2017-09: 3D Provincial Geological Framework Model of Alberta, Version 1 - Methodology The 3D PGF model contains 32 geological zones ranging in resolution from member, formation, or group level to mixed formation, group and/or period level. The modelled zones from surface to the base of the model are: sediment above bedrock, Paskapoo Formation, Scollard Formation, Battle Formation, undifferentiated Horseshoe Canyon Formation / Wapiti Formation / St. Mary River Formation / Belly River Group / Bearpaw Formation equivalent interval, upper Bearpaw interval, Strathmore Member, lower Bearpaw interval, Dinosaur Park Formation, Oldman Formation, Foremost Formation, undifferentiated Lea Park Formation / Colorado Group / Smoky Group / Fort St. John Group equivalent interval, Pakowki Formation, Milk River Formation to base of the Fish Scales Formation interval,  base of the Fish Scales Formation to Viking Formation / Bow Island Formation / Peace River Formation equivalent interval,  Viking Formation / Bow Island Formation / Peace River Formation equivalent interval to Mannville Group equivalent interval,  Mannville Group equivalent to sub-Cretaceous unconformity interval, undifferentiated Jurassic / Triassic / Permian / Carboniferous to Banff Formation interval, Banff Formation to Wabamun Group interval, Wabamun Group, Winterburn Group, undifferentiated Woodbend Group shales above Leduc or Duvernay formations (WOOD A), undifferentiated Woodbend Group shales with no Leduc or Duvernay formations below (WOOD B), Duvernay Formation, Leduc Formation, Cooking Lake Formation, Majeau Lake Formation, Waterways Formation, Swan Hills / Slave Point formations interval, Fort Vermilion Formation, Elk Point Group to Precambrian interval, and Precambrian to 5000 m below sea level interval. The model was created in Schlumberger’s Petrel 2015 (Petrel) and has been exported in nonproprietary formats for use in other software.
