Abstract

In order to clarify some of the issues regarding the mineralogical content and the source area of the Cretaceous deposits from Ampoi Valley basin (Southern Apuseni Mountains) fourteen lithologic logs were drawn from the Ampoi Valley both side tributaries (Slatinii, Ruzi, Vâltori, Valea lui Paul, Fenes, Calineasa, Fierului Brook, Bobului, Satului, Tauţi, Galaţi, Presaca Ampoiului, Valea Mica and Valea Mare brooks). The main sedimentary rock types were identified (conglomerates, wacke and lithic sandstones, clays, and marls). The sandstones were classified according to the ternary diagrams. Their petrographic features revealed both a magmatic and a metamorphic source area for them.
