The 950/560 nm spectral ratio has been traditionally used as a qualitative indicator or lunar soil maturity because the 950 nm band falls within the major Fe2+ mineral absorption bands near 1 &mgr;m characteristic of relatively immature, crystalline surfaces. Since there are several other processes unrelated to maturation that may affect this ratio value, we have evaluated the 950/730 nm ratio as a potentially better measured of the relative 1-&mgr;m band strength. We find that the 950/730 nm ratio appears to be much more sensitive to the 1 &mgr;m band depth, but feel that other unknown variables preclude using these single ratios to provide meaningful quantitative results at this time. Because of problems with near-IR scattering in vidicon detectors used in previous studies, we have measured the scattering properties of our two CCDs and conclude that any scattering is negligible. ¿American Geophysical Union 1991
