Horn River Formation, Shale formation in Northwest Territories, Canada
The Horn River Formation extends over 320 meters in thickness and contains dark siliceous shale with argillaceous bituminous limestone deposits.
E.J. Whittaker first documented this geological structure in 1922 along the banks of the Horn River, a tributary of the Mackenzie River.
The formation represents a significant part of the Western Canadian Sedimentary Basin, contributing to the understanding of Middle to Late Devonian geology.
Natural gas extraction companies utilize horizontal drilling and fracturing techniques to access the estimated 500 trillion cubic feet of gas within the formation.
The formation includes three distinct members: Muskwa with radioactive shale, Otter Park with grey calcareous shale, and Evie with black silty limestone.
