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

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

Potential industrial clays of Alberta : a preliminary assessment, Part II

From the same area, samples of Kaskapau Formation dry well, firing range is moderate to long, and the milk chocolate brown colour could be acceptable in "earth colour" pottery or structural clay products. A sample from the Bearpaw Formation in the ... Show Abstract

Potential industrial clays of Alberta : a preliminary assessment, Part I

Potential industrial clays of Alberta : a preliminary assessment, Part I Clays from the Luscar Formation show the most potential as they work well, extrude well, and dry well in addition to firing to an appealing dark chocolate colour at the end of ... Show Abstract

Sand and Gravel Resources of the Pelican (West Central Portion of 83P) Map Area, Alberta

The aggregate materials present in the west central portion of the Pelican (NTS 83P) map area were studied in 1986 to provide information on the distribution and characteristics of the resource. The program consisted of compiling existing ... Show Abstract
