Redknife Formation, Geological formation in Northwest Territories, Canada
The Redknife Formation contains layers of shale, limestone, siltstone, and dolomite that extend across the Western Canadian Sedimentary Basin.
Belyea and McLaren first documented this formation in 1962 along the Trout River banks, establishing it as a significant Late Devonian geological structure.
Scientists study the formation's coral and brachiopod fossils to understand marine environments that existed between 385 and 359 million years ago.
The formation reaches depths of 237 meters at the Briggs Turkey Lake well, located at coordinates 61°07'30"N and 120°22'30"W.
Natural gas extraction occurs in the Jean Marie Member section, particularly within the Greater Sierra field east of Fort Nelson.
