 Abstract
In the structural development as imbricated folds structures of the Paleogene-Miocene Formations belonging to Tarcău Unit from Eastern Carpathian Curvature, one of the geological landmark can be considered the breccia deposit that repeats with increasing thickness from the inside to outside, revealing clear characters of debris-flow deposit. In the paper were determined several adjacent descriptive facies, which then used as interpretative facies allows genetic sedimentological remarks on the whole ensemble of Tarcău Unit.

 Rezumat
Pe fondul structural al dezvoltării in cute solzi a formațiunilor paleogene ale Unității de Tarcău de la curbura Carpaților Orientali, unul din repere poate fi considerat depozitul brecios ce se repeta cu grosimi crescătoare de la interior către exterior, relevând caractere nete de depozit de tip debris-flow. In lucrare s-au determinat mai multe faciesuri descriptive adiacente, care utilizate apoi ca faciesuri interpretative permit considerații sedimentologice genetice asupra întregului ansamblu al Unității de Tarcău.
