Comment:
The color reflectance of dried sediment was measured with an X-Rite spectrophotometer, Model 500 Series, using the CIE* system, with L* a measure of black to white, a* (blue to red) and b* (yellow to green. The prepared dry samples were tapped into a 2.5 cm dia. aluminum XRD holder, overlain by a clear glass slide, and measured. A Pantone Color Chip (4705) was measured repeatedly to evaluate instrument drift.
