The Pre-Variscan sequence of the Carnic Alps - an introduction

An updated stratigraphic scheme of the Pre-Variscan sequence of the Carnic Alps is proposed herein. Lithostratigraphic units have been carefully revised and homo- genized in each investigated time slice. Recognized units have been formalized accordingly. The data on the age of the boundaries have been improved as well. The succession spans the Middle Ordovician - early Pennsylvanian interval and has been formally divided in 36 formations, providing a sound reference for future geological studies in this part of the Carnic Alps and enabling a more global correlation with other paleogeographical domains
