Minor Elements in Some Carbonates

Abstract

An investigation of minor elements distribution in sedimentary and metamorphic carbonates was made. A copper oxide D. C. Arc Technique of spectrographic analysis was developed for determination of minor elements in carbonates. Forty-five samples of carbonates extracted from Paleozoic limestones of Alberta and Ontario, Precambrian marbles of Ontario and from Grenville Lens and Vein Carbonates of Ontario and Quebec were analyzed, and the concentrations of Mg, Mn, Fe, Sr, Ba, Pb, Al, Si, Ti, B, Cr, and Ni were determined. The structure and some chemical properties of carbonates were discussed. An attempt to locate the minor elements in the crystal structure was made.
