On the graptolite schist's formation, Silurian-Lower Devonian, in the Carpatho-Balkanides of eastern Serbia [PDF]
The fabric of the Silurian and a part of the Lower Devonian in the Carpatho-Balkanides of eastern Serbia, i.e. in two large geotectonic units, the Kučaj Unit (Getic) and the Luznica Unit (West Kraishte), is reviewed in this paper.
