Debolt Formation
The Debolt Formation is a stratigraphical unit of Meramecian age in the Western Canadian Sedimentary Basin.
It takes the name from the hamlet of Debolt, Alberta, and was first described in the Amerada Crown GF23-11 well near Debolt by G. Macauley in 1958.〔Macauley, G., 1958. Late Paleozoic of Peace River area, Alberta. In: Jurassic and Carboniferous of western Canada; Goodman, A.J. (Ed.), p. 289-308. American Association of Petroleum Geologists〕
==Lithology==
The Debolt Formation is commonly subdivided into a lower and upper unit. Lower Debolt rocks are bioclastic limestones deposited on a stable carbonate ramp. These lower Debolt rocks are rarely dolomitized and therefore have little porosity or commercial use. Upper Debolt sedimentation is characterized by a number of shallowing upwards facies. At the base of the Upper Debolt is distal and medial ramp argillaceous limestone facies with limited laminations and thin bedding. These argillaceous facies rarely contain clean carbonate interbeds in the medial ramp setting, predominately wackestones and packestones. These facies are followed by a capping proximal ramp/shoal facies with abundant skeletal packstones and grainstones.
