Geochemical dispersion of Uranium in the sediments of Krishna delta and its offshore region, east coast of India.

A. S. R. Swamy and V. V. S. S. Ttlak

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.
