B. Riegl et We. Piller, Biostromal coral facies - A Miocene example from the Leitha Limestone (Austria) and its actualistic interpretation, PALAIOS, 15(5), 2000, pp. 399-413
Coral-rich strata of the Leitha Limestone of Badenian age (Middle Miocene)
at the type-locality in Grosshoeflein (Burgenland province, Austria) were r
e-interpreted from an actualistic viewpoint in comparison with Recent Baham
ian and Arabian Gulf coral communities. The investigated outcrop (quarry 'F
enk' is interpreted as a sequence of framebuilding coral carpets and non-fr
amebuilding biostromal coral communities, alternating with bryozoan and cor
allinacean calcarenites and bivalve beds. No indication for the presence of
a reef was found. In total, a sequence of 10 coral intervals was observed,
which can be grouped into 2 coral carpet types thigh carpet framework, low
bushy framework), four non-framework communities, and one bivalve/coral co
mmunity. Within this sequence, no unequivocal indication for sea-level chan
ges at the time of deposition was apparent. The different coral facies are
interpreted as having been deposited within roughly the same water depth as
Recent coral systems observed in the Bahamas (Andros, Exuma Cays) and the
Arabian Gulf (Dubai, UAE) According to the model presented, the facies mere
ly represent different lateral positions within the same spatially highly c
omplex environment. A distribution map of benthic biota in the Arabian Gulf
(Jebel Ali, Dubai, UAE) was used to illustrate the likely lateral distribu
tion of the Miocene facies.
