"Table 5. Mineral percentages (in relative weight percentage) for samples from holes within the Buried Basement Transect area," based on X-ray diffraction analyses of random bulk powders. Notes: wt% = weight percentage. Mineral abbreviations: Smec. = smectite; Mica = muscovite + illite; Chlor. = chlorite; Phyllo. = total phyllosilicates; Felds. = total feldspar; and Calc. = calcite. S = sand; MS = muddy sand; CS = clayey silt/silty sand; MCS = mixed carbonate/siliciclastic; and * = whole round Interval Depth Relative mineral abundance (wt%) from XRD peak area Core Type Section (cm) (mbsf) Lithology Smec.
