Description 219-223
Extensive
beachrock exposures in vertical cliffs of wave cut terraces were observed along
the coastal regions of Modern Godavari delta. Environmental association,
geographic location, sedimentary structures, texture and petrography of these
rocks reveal that they are sediments deposited at the swash zone of beach face.
In view of prevalent rapid deposition during earlier progradational phase of
the delta, the sediments got buried before inheriting the characteristics of
beach. With due progradation of the delta, these sands were cemented at an
elevated location in supratidal regions. Their present location

at or slightly below the low
tide water line indicates ongoing sealevel rise coupled with coastal
submergence. A conservative estimate shows 1.34 m of combined effects of these
two processes.
