    Mineral compositions of the rock samples were determined by the external standard method of Chung . This method requires an internal reference as well as reference intensity ratio (RIR). The RIR is the ratio of the integrated intensity of a reference mineral to that of unknown mineral in a 1:1 mixture.

      The Rietveld heavy mineral method has been tested using an Eocene sandstone from the Medicine Pole Hills (MPH) south of Rhame, North Dakota. The success of the Rietveld method is evaluated by comparison with weight percentages based on volume percentages (number and size of grains) and calculated densities of each heavy mineral.

      • Abstract CORE

        Rietveld refinements were carried out using GSAS and an averaging technique. Based on optical/SEM work, heavy minerals in the sandstone consist of diopside (56.1%), edenite (19.9%), epidote (6.1%), augite (5.3%), paragasite (4.2%), almandine-rich garnet (3.6%), and ten minor phases (4.8%).

        If Rietveld refinement can be used to successfully quantify heavy mineral abundances, future work will focus on using refinements to obtain compositional information about solid solution minerals. It is hoped that the Rietveld method will provide more detailed information about the heavy minerals, and thus the source rocks, allowing more
