A sequence of competent Mesozoic rocks, characteristic of the Pieniny Klippen Belt, is cropping out at Poiana Botizii in the northern part of the Romanian Carpathians. It represents the interval late Middle Jurassic-earliest Lower Cretaceous. The formations are typical of the Alpine Mediterranean province and their succession is the following: pyroclastic rocks, banded radiolarian cherts, calcarenites bearing ophiolite fragments, limestone with nodular cherts, calcareous mudstones and siltstones with aptychi (Rosso ad Aptychus), Rosso Ammonitico Saccocoma limestones, pelagic Calpionellid limestones (Biancone). The Mesozoic sequence at Poiana Botizii is considered as belonging to a new and outer tectonic subunit of the Magura Nappe.
