The Detection and Quantification of Low Concentrations of Quartz in Dolostone by X-Ray Powder Diffraction

Abstract

AbstractQuartz in dolostone can be determined quantitatively down to 0.03 weight percent using a standard preparation procedure for the sample and absolute integrated intensity measurements. Measurement reproducibilities of 3.2% were obtained. Calibration curves determined by spiking low-quartz dolostone allowed concentrations of 2.0 weight percent or lower to be established. Higher concentrations of quartz in some related soil samples were determined by comparing the absolute integrated intensity with that obtained from a pure quartz sample prepared in the same manner.
