Abstract |
: |
The Middle Eocene 270 m thick carbonate sequence of Jabal
Hafit, to the south of Al Ain City, UAE is one of the thickest nummulitic
buildups, not only in the Arabian Peninsula but also in the Middle
East. The sequence is characterized by highly diverse and frequent faunal
content. Moreover, many taxa attain gigantic sizes, e.g. Nummulites
cf. lyeli, N. maximus, Assilina gigantea, gastropods, burrowing echinoids,
thick-shelled oysters and others. The sequence shows very little
or no lithological and/or paleontological lateral variations all over the
study area, which reflects the homogeneity of the depositional environment.
On the other hand, the vertical time-changes are remarkable. The
rhythmic appearance of the larger foraminiferal (Nummulites and/or As-
silina, Alveoloina) buildups with one or two species of each, and the
non-or poorly nummulitic zones in-between, is an indication of oscillating
sea level and syntectonic sedimentation. The chrono-and biostratigraphic
setting of the studied sequence confirms Lutetian age. |
