- Abstract
Continental deposits especially conglomerates have always been a challenge to geologists because of the lack of fauna and of the petrographic diversity of their particles. The continental deposits located in the south - western part of the Transylvanian Basin make no exception. This paper presents the sedimentological and facial features of the Şard Formation, which is cropping out on the right bank of the Ampoi River. Among the various sedimentary formations exposed in this region, the Upper Cretaceous to Lower Tertiary successions are of special interest, marking the sedimentary environment's evolution near the Cretaceous - Tertiary boundary. At this level a reddish continental formation was deposited and its formation is typical for alluvial depositional system (braided rivers). Detailed lithological columns have been logged recording textural parameters like pebbles morphometry and granulometry as well as the sedimentary structures and clast composition, over the 60 m thickness of the outcropping section
