Abstract
Micromorphology, XRD analyses and SEM studies of rhizoliths from Late Middle Pleistocene yellowish brown silty fluvial sediments of Yedurwad i reveal that calcium carbonate has a localized source. Silica and cal cium carbonate are formed by the plant roots through their metabolic a ctivity creating a favourable microenvironment for the processes of Si O2 and CaCO3 precipitation and replacement.
