Шаблон:Infobox rockunit The Drina Formation ("Drina Formacija") is a stratigraphic unit in Bosnia and Herzegovina and Serbia.[1] It was deposited between the Cambrian and the Carboniferous onto Neoproterozoic basement.[2] It is composed of clastic sediments, limestone and volcanic rocks.[3] The Drina Formation is conformably overlain by the Golja Formation.[2]
The formation is part of the Drina Ivanjica Unit and was overprinted by the Variscan and Alpine Orogeny.[2]
The oldest fossils are acritarch phytoplancton and spores, which indicate a Cambrian to Ordovician age. The youngest fossils are conodonts which indicate Viséan to Namurian age.[2]
