wave generated movement dies out rapidly with depth " ( Pettijohn , 1957 , p .

result of disturbance of noncoherent granular sediments ( Shrock , 1948 , p . 95 ) .

Presence of these cubic pseudomorphs also suggests that the intermittent
flooding took place after a time when already deposited sediments had been
sufficiently indurated . This is indicated by the fact that the perfect boundaries of
