Quantitative determination of dawsonite in Green River Shale by powder-sample X-ray diffraction; effect of grinding Quantitative determination of dawsonite in Green River Shale by powder-sample X-ray diffraction; effect of grinding
In an effort to evaluate the method of quantitative analysis by X-ray diffraction as a means of determining dawsonite abundances in Green River" oil shale, we performed a series of grinding experiments. Weighed mixtures of dawsonite + quartz and dawsonite + quartz + shale were ground for preset lengths of time, and the following X-ray diffraction peaks were measured for intensity...
