Micromorphology, XRD analyses and SEM studies of rhizoliths from Late Middle Pleistocene yellowish brown silty fluvial sediments of Yedurwadi reveal that calcium carbonate has a localized source. Silica and calcium carbonate are formed by the plant ischolar_mains through their metabolic activity creating a favourable microenvironment for the processes of SiO2 and CaCO3 precipitation and replacement.
