Alberta clays and shales : summary of ceramic properties

Ceramic test data for more than 200 deposits of clays and shales in Alberta resulted largely from early investigations of the Federal Department of Mines (1912-15, 1932) supplemented by more recent work of Alberta Research ... Show Abstract

Limestone resources of Alberta

Abstract: Seven areas in Alberta, close to transportation facilities, were studied to determine quality and reserves of high-calcium limestone.Three formational units in the foothills and mountain regions are of importance. The lower Cambrian Eldon Formation has a limited potential in the Exshaw area where it was previously exploited for limemaking. The Upper Devonian Palliser Formation contains large reserves of high-grade rock in the Crowsnest, Exshaw, Cadomin, and Brûlé areas. At one time a lime plant operated successfully at Cadomin, utilizing rock from this formation. Present production of Palliser limestone at Exshaw and Cadomin is used for cement- making. The Mississippian Livingstone Formation is of proven high quality in the Crowsnest, Blairmore, Exshaw, and Nordegg areas. Formerly a cement plant operated at Blairmore, utilizing limestone from this formation; new quarries have been opened in the Crowsnest and Exshaw areas to supply lime plants.Quality of foothills and mountain limestone deposits is often lowered by the presence of siliceous and dolomitic beds. Compositional variation is a particular problem in the Livingstone Formation.Near Fort McMurray, in northeastern Alberta, the large resources of limestone in the Moberly Member of the Upper Devonian Waterways Formation appear to be of moderate quality. The calcium carbonate grades are affected in places by an abundance of silica and alumina.

Alberta Bentonites

Low yields, high grit content, or thick overburden reduce the desirability of other deposits.The paucity of glass shards and the mineralogy of the sand and silt fractions suggest rhyodacite as the composition of the parent volcanic ash for each ... Show Abstract

Bromide, iodide and boron in Alberta formation waters

Bromide contents up to 2786 mg/L were found in high calcium and magnesium brines associated with evaporites in the Upper Devonian Beaverhill Lake Formation and Middle Devonian Elk Point Group. The most extensive regions of high-iodide formation ... Show Abstract

The ceramic potential of Alberta clays and shales

Many geographical areas and geological formations were missed when the ceramic suitability of materials was studied early this century. Geological formations that are useful for the production of structural clay products or pottery are Pleistocene ... Show Abstract
