Quantitative evaluation of color measurements II. Analysis of Munsell color values from the Colton and Green River Formations (Eocene, central Utah)
A case study of Munsell color measurements from the Eocene Colton and Green River Formations in central Utah shows how easily stereoscopic triaxial scatterplots can display the limited overlap of colors within lacustrine and alluvial facies. Grays, drabbish yellow-greens, greens, and 10 YRs are associated with lacustrine limestones and other known lacustrine facies, whereas other yellow-reds and reds are predominantly associated with terrestrial deposits, including fluvial sandstones. Lake beds in Colton Formation show a greater variety of color than those in the Green River Formation, both in terms of a greater range of hues and more extreme lightness and darknesses, apparently reflecting the fact that the Green...
