27th IAS Meeting of Sedimentology, Alghero, İtalya, 20 - 23 Eylül 2009, ss.135-139, (Tam Metin Bildiri)
Middle Miocene reefs, South-Eastern Turkey, are widely exposed in the Iskenderun and adjacent basins, which are divided into Iskenderun (IS) Osmaniye (OS) and Hatay (IIS) sub-basins, They show a nearly similar depositional history through the Miocene time. In the Serravallian, the coral patch reefs were simultaneously developed in this sub-basin, either directly on the fault-induced topographic highs or on the fluvial conglomerale. The reefs are locally overlain by high-energy bioturbated and nodular carbonate shore deposits formed during maximum shoreline transgression. Through the end of Middle Miocene, the reefal areas evolved into slope and basin intervals resulted from rate of maximum transgression. Meanwhile in the OS, short regression periods took place depending on a retrograding transgression stage which caused formation of estuary channels reefs. This short regressive interval was followed by deltaic progradation by means of the establishment of new accommodation space triggering a second event of transgression. A major regressive stage starting in the early late Miocene caused the deposition of siliciclastic shore-lagoon complex, and Messinnian evaporites were lastly precipitated in the maximum regression stage of the Miocene sea that was up to Pliocene transgression starting with deposition of Lago-Mare type facies live Miocene unit is represented by Transgressive and Regressive Systems Tract (TST, RST) delineated by Maximum Flooding Surface (MFS) and mineralized hardground. On the other hand, some short intervals caused uplifting. local deepening of the carbonate platform loading to the development of paleosol, local estuary and coral carpets covered by thin pelagic interbeds within the reefal succession.
