The salt deposits of the Middle Devonian Elk Point Group extend from North Dakota to Canada9s Northwest Territories. Subsurface knowledge is best in Saskatchewan. Here the most wide-spread of these deposits, the Prairie Formation, reaches a maximum thickness of 670 feet and contains the extensive potash ores now being developed. The Prairie salt beds overlie thin carbonates containing reefs. These sediments form part of a depositional sequence starting with thin shales and grading upward to… Expand
The Steepbank Formation: a paleokarst diamictite deposit in the Athabasca Oil Sands region of northeastern Alberta, Canada
Abstract The name “Steepbank Formation” is proposed for a paleokarst diamictite deposit that is present along the margins of the Middle Devonian Prairie Evaporite Formation in the Western Canada andExpand
The Viking Formation (Lower Cretaceous) of southeastern Saskatchewan.
The Viking Formation is a dominantly regressive sequence of sandstones, laid down in a shallow, marine epicontinental basin. The Viking sequence of southeastern Saskatchewan was deposited on theExpand
Winnipegosis Mounds and Prairie Evaporite Formation of Saskatchewan--Seismic Study
Seismic surveys have been used to investigate the Prairie Evaporite and Winnipegosis Formations in the vicinity of some potash mines in south-central Saskatchewan. The geophysical data, together withExpand
Economic geology of southern Saskatchewan potash mines
Abstract Canadian commercial potash deposits are located in the southern Saskatchewan area of a Middle Devonian evaporite basin that extends across western Canada and into adjacent areas ofExpand
Hypogene Karst Collapse of the Devonian Prairie Evaporite Basin in Western Canada
Regional dissolution trends configured the Middle Devonian Prairie Evaporite basin across Western Canada, resulting in the largest known collapse of a hypogene evaporite karst dominated by haliteExpand
Evaporite dissolution and development of karst features on the rolling plains of the texas panhandle
More than 400 dolines, consisting of collapse sinkholes and closed depressions, occur in Hall and Briscoe Counties, Texas. Of these, at least 36 sinkholes and two depressions formed between 1940 andExpand

Abstract On the Eastern Flank of the South Oman Salt Basin lies a Cambrian to Recent sequence much affected by the withdrawal and dissolution of underlying Infracambrian salt. Salt withdrawal beganExpand
Salt Solution and Subsidence Structures, Wyoming, North Dakota, and Montana
Salt beds with a thickness range of a few feet to 600 ft are common in rocks of Middle Devonian and Permian ages in the northern Rocky Mountain area. Variations in thickness of these salt beds inExpand
Syndepositional architecture of the northern Athabasca Oil Sands Deposit, northeastern Alberta
Salt dissolution collapse-subsidence is proposed as the dominant tectono-stratigraphic control on the deposition of major sand trends across the northern Athabasca Oil Sands Deposit. Salt removalExpand
The Petrofka landslide, Saskatchewan
Both abutments and all piers of the Petrofka bridge are on a landslide. The bridge has performed satisfactorily for 23 years, indicating the factor of safety of the Petrofka landslide is greater thanExpand
