The structure of red mud deposits of Seydisehir, Turkey were investiga
ted by simple but effective statistical analysis. The results obtained
under variable iron oxide contents were used to generate an empirical
relationship by plotting, at different scales, D-1/D-2, versus K-1/K-
2, where D-1 is the percent iron oxide, D-2 is the mean percent iron o
xide, K-1 is the percent silicon dioxide and K-2 is the mean percent s
ilicon dioxide. As a result of these trials, it was found that the use
of logarithmic coordinates gave a straight line with the empirical eq
uation for the system in question being: D-1 = 1.0092 . D-2 K-1(0.02)
. K-2(-0.02). (C) 1998 Elsevier Science B.V.
