- Other minerals present in rather small concentrations include those bearing Ti, Ca, and Na (i.e. rutile, plagioclase, etc.) which are not shown here. Amorphous minerals not detected by XRD are also not shown. Mineral contents determined by the XRD-Rietveld approach was converted to elemental composition (i.e. Fe and Al) using factors derived from the ideal chemical formulae of minerals shown above.
