Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) were used to analyze acid residues from heavy mineral separates, polished grain mounts, and clays from sampled sediments...
-
Splits of samples were prepared of heavy mineral separates and bulk separates less than 2mm for analysis using X-ray diffraction (XRD) and results were interpreted to identify mineral components...
