Аннотация:The lower part of the Maykop Group sediments of the Crimea–Caucasus region were studied.
Available outcrops of every structurefacies zone were examined and the sandstone composition was deter
mined in thin sections: as a result five main lithologies were distinguished. Sharply discrepant provenance
sources for the Kerch Peninsula, Sochi area, and Abkhazia for the Early Oligocene are suggested and those
feeding areas are assumed to be variably remote from a sedimentary basin. An updated Rupelian (early Oli
gocene) palaeogeographic scheme of the Crimea–Caucasus region is proposed.
