Trace-element geochemical analyses were performed by inductive coupled plasma-atomic emission spectroscopy (ICP-AES) methods after four-acid, near-total digestion. This method of digestion is possibly incomplete for some elements (Ba, Cr, Ti, W) and may result in lower analytical results for these elements. Five samples were analyzed for non-carbonate carbon using LECO induction furnace pyrolysis following dilute acid digestion.
