In profile A, Si[O.sub.2], and [Al.sub.2][O.sub.3] are strongly and positively correlated (r = 1.0~0.800) with alkali elements but are strongly and negatively correlated with alkaline earth elements, density, and pH value.
Moreover, the concentration of alkaline earth elements, density, and the LOI of PC1 exceed 0.8, 0.588, and 0.322, respectively.
The alkali and alkaline earth elements are almost completely depleted in all profiles.
If the trivalent rare earth element is partially doped with the divalent alkaline earth element, the doped manganese oxides [RE.sub.1-x][A.sub.x]MnO (Ln: the trivalent rare earth elements, A: Ca, Sr, Ba) are formed with novel and rich physical phenomena since the discovery of colossal magnetoresistance (CMR) [1-3].
