The Jurassic radiolarian cherts of Albania are included both in the ophiolitic successions of
the Mirdita zone (Kalur Cherts), which have been interpreted as remains of the Tethyan
oceanic lithosphere, and in carbonate successions presumably deposited on the continental
margin of the Tethys.
The data available on the radiolarian cherts of Albania are summarized and updated in this
paper. The data from 12 sections of radiolarian cherts belonging to the ophiolite-bearing
successions are examined and compared with data from 14 sections of radiolarian cherts
belonging to the carbonate (pelagic and paltformic) successions.
Stratigraphical data of the top of the ophiolite sequence and of the carbonate peripheral units
indicate their similar paleogeographical conditions and close relations between them.
