In the Klape Unit of the Pieniny Klippen Belt the Albian conglomerates with clasts of exotic carbonates, clastic sediments and also volcanic and plutonic rocks are relatively widespread. In the small area near the town Povażska Bystrica also scarce blueschist clasts of variegated petrographic types have been found. Three groups of starting rocks can be discerned for blueschists: pelagic sediments, metamorphic rocks (amphibolites, gneisses) and volcanic rocks. Based on immobile trace element (HFSE, REE) distribution two petrogenetic types of volcanic rocks have been identified: basalts with BABB signature and calc-alkaline basaltic andesites to rhyolites. Source of these rocks was probably a nappe stack located in the Carpathian interior and created in the Late Jurassic time as a result of subduction of the oceanic crust and adjacent volcanic arc and followed by collision during the Meliata Ocean closure

Albskie zlepieńce jednostki klapskiej pienińskiego pasa skałkowego zawierające egzotyki skał węglanowych, klastycznych, jak również wulkanicznych i plutonicznych są szeroko rozprzestrzenione. Na małym obszarze w okolicy Povażskiej Bystricy (Słowacja zachodnia) w kilku stanowiskach znaleziono rzadkie egzotyki zróżnicowanych petrograficznie łupków glaukofanowych. Wyróżniono trzy grupy pierwotnych utworów przekształconych w te łupki: osady pelagiczne, skały metamorficzne (amfibolity, gnejsy) i skały wulkaniczne. W oparciu o niestabilne pierwiastki śladowe (HFSE, REE) zidentyfikowano dwa typy petrogenetyczne skał wulkanicznych: bazalty o cechach bazaltów obszarów zaułkowych (BABB) oraz wapniowo-alkaliczne andezyty i ryolity bazaltowe. Obszarem źródłowym tych skał były prawdopodobnie spłaszczowinowane jednostki zlokalizowane w obrębie Karpat wewnętrznych, powstałe w późnej jurze jako rezultat subdukcji skorupy oceanicznej i utworzonego w związku z tym łuku wulkanicznego, w następstwie kolizji podczas zamykania się oceanu Meliaty
