EDS spectrum of the area between the larger dolomite crystals in the outer
wall rock sample from EY56 site in the Western Borehole. A strong iron
signal is observed. Not shown, but detected in the surrounding areas are
barite crystals and gypsum particles. Samples are Au-Pd coated. Analysis
by Spilde, Northup, and Boston.
