Cartoons of the evolution of the Cajiloa tidalites
succession, showing (
a
) the empty seafl oor low created by
emplacement of the slump (MTD 1 in Fig.
14.12
); (
b
) the fi rst
large turbidite bed which mantled the seafl oor low and partially
smoothed out the seafl oor roughness; (
c
) the turbidite from
(
b
) above the seafl oor low was reworked by tidal currents and
redeposited into the seafl oor low. After a hiatus during which the
interval above the lower tidalites became extensively bioturbated;
(
d
) another turbidite was deposited and reworked into more
tidalites in the seafl oor low. This sequence was repeated a number
of times until the seafl oor low was fi lled and subsequently over-
lain by another slump. Other tidalite successions in the Cajiloa
system exhibit a very similar evolution
