Distribution and Analysis of High-Purity Magnesian Limestones in the United States. Final Report

摘要

A literature and operations data study was made of the distribution of magnesian limestones in the United States. Based upon this work 13 field samples were collected for wet chemical and x-ray analyses. The distribution of magnesian limestones in the United States is discussed as is the occurrence of magnesium in limestone. Magnesian limestone was found to be distributed in a similar pattern to that of carboate rocks in general, but on a much more restrictive basis. Magnesian limestones were found to comprise a relatively minor percentage of the total number of carbonate rocks present in the United States. X-ray studies of the field samples could not confirm the presence of magnesium in solid solution with calcite in any of the formations tested. 12 figures. (ERA citation 08:013744)
