Abstract

The uranium content is estimated in the clay fraction (<4µ) of the sediments of river channel (fresh water), estuary, tidal creek and marine environments of the Krishna Delta. Its dispersion pattern in various environments and sub-environments is discussed in relation to montmorillonite, organic matter, phosphate and copper contents of the sediments. Physico-chemical conditions of the environments and organic matter appear to play a greater role in the fixation of uranium than montmorillonite.
