Description 929-933
Geochemical
studies were carried out for the clays of the coastal red sediments from
Yerrayyapalem to Chepalakancheru to understand the distribution, sources and
processes by which the major and minor elements are present in the clays of red
sediments. Kaolinite, illite and montmorillonite are the clay mineral
assemblage in the red sediments with decreasing abundance. Results show that
iron is fixed as oxide coatings on clays while titanium is associated with the
iron oxide coatings. Low sodium and potassium concentration in the red
sediments indicates that the leaching of alkalies is complete in the source
area.Low concentration of Ca and Mg in red sediments indicates that it is
leached from the sediments and deposited as calcium in the red sediments
itself. Manganese content is associated with oxide coatings in the red sand
sediments.
