Carbonate rocks in the Black Sea basin: indicators for shallow water and subaerial exposure during Miocene--Pliocene time
Stoffers P. , Muller G. ,
Abstract:
Drilling in the Black Sea in general revealed three types of sediments: terrigenous, chemical, and biogenic. Terrigenous muds predominate in the Pleistocene whereas chemical sediments are abundant in the lower Pleistocene--Pliocene to Late Miocene sedimentary section. Biogenic constituents play a minor role only. The chemical sediments include calcite (lake chalk), Mg-calcite, aragonite, siderite and dolomite. Among these, the dolomites of Pliocene to Late Miocene age are most interesting. They were encountered in the two drill sites close to the Bosporus drilled in 2115 to 1750 m water depth, respectively. The dolomites show a great variety of criteria (e.g. intraclasts, algae mats, crusts, pellets, oolites), indicating a shallow water environment with occasional subaerial exposure and supratidal evaporitic conditions. The formation of these shallow water carbonates in the Black Sea is supposed to correlate with the Messinian salinity crisis in the Mediterranean
