Abstract:
During Ocean Drilling Program Leg 199 in the equatorial Pacific, visible and near-infrared spectroscopy (VNIS) was used to measure the reflectance spectra (350-2500 nm) of 1343 sediment samples. Reflectance spectra were also measured for a suite of 60 samples of known mineralogy, thereby providing a local ground-truth calibration of spectral features to percentages of calcite, opal, smectite, and illite. The associated algorithm was used to calculate mineral percentages from the 1343 spectra. Using multiple regression and VNIS mineralogy, multisensor track physical properties and light spectroscopy data were then converted into continuous high-resolution mineralogy logs.

Comment:
Ground-truth data for calcite percentages for ODP Sites 199-1215, 1218, and 1219 are from Lyle, Wilson, Janecek, et al. (2002). Ground-truth data from site survey cores and Leg 162 are from Olivarez-Lyle and Lyle (2002). Clay was found by subtracting percent calcite from 100%. Opal was assumed to be negligible. The dominant clay mineral (smectite or illite) was identified from VNIS spectra.
