SEM image of the ocher-colored corrosion residue from EY56, Western Borehole. Light-colored areas of image may be apatite and barite. See EDS analysis below. Photo by Spilde, Northup, and Boston.

EDS spectrum of ocher-colored corrosion residue from EY56, Western Borehole. Spectrum shows a strong iron presence and minor amounts of vanadium, sulfur, phosphorus, and clay elements. Samples are Au-Pd coated. Analysis by Spilde, Northup, and Boston.

EDS spectrum of ocher-colored corrosion residue from EY56, Western Borehole. Spectrum shows rare earth peaks (lanthanum, cerium, and neodymium) associated with a strong phosphorus peak. Samples are Au-Pd coated. Analysis by Spilde, Northup, and Boston.
