The dark cutans in the top of the B-horizon show little if any sign of discolouration, and there are no strong brown mottles in the upper part of the B-horizon.
The correlation coefficients for linear regressions in Table 2 indicate that the Bt-horizon redness rating of Hurst (1977); the matrix + mottles, and matrix + mottles + clay films indices of Mokma and Cremeens (1991); and the chroma + hue index of Evans and Franzmeier (1988), are more or less equally useful for the prediction of the duration of waterlogging at the bottom of the E-horizon.
At Gatum most mottles in the B-horizon appear to be conversions of the fossil red mottles still present lower down in the profile (see Brouwer and Fitzpatrick 2000, 2002 this issue).
