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

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. Formerly a cement plant operated ... Show Abstract

Alberta Bentonites

Abstract: Suspension properties of bentonites from the nine areas in Alberta where deposits are thicker than 1 foot indicate that production of high-swelling bentonite probably will remain limited to deposits presently being mined. 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 deposit. Absence of allogenic material indicates that differences in the amount of clastic constituents within and between deposits are the result of differences of original mineralogy and diagenetic alteration. Clay content can be related to the amount of sand-and silt-sized volcanic glass altering to montmorillonite. Evidence suggests no preference for diagenesis or adsorption from groundwater to explain the origin and distribution of Na, Ca + Mg, and Fe.Multiple regression analysis of seven compositional properties shows that 81 percent of the variation in yield (bbl/T) of 15-centipoise mud can be attributed to their concomitant variation; however, 72 percent of the variation in yield can be attributed to one property (clay content). The remaining variables ( clay, exchangeable Na, exchangeable Ca + Mg, and contents and CEC) contribute little additional precision to the regression analysis when clay content is included in the equation Place Keywords 72e 72l 72m 73d 73e 73l 73m 82g 82h 82i 82j 82n 82o 82p 83a 83b 83c 83d 83e 83f 83g 83h 83i 83j 83k 83l 83m 83n 83o 83p alberta alberta foothills alberta plains battle river canada onoway Theme Keywords bentonite dresser minerals geology

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

Calcium and magnesium in Alberta brines

Calcium and magnesium in Alberta brines Approximately 850 subsurface brines from Alberta containing more than 20,000 mg/L calcium and more than 3,000 mg/L magnesium were studied to determine their commercial potential. Knowledge of the regional ... Show Abstract
