Abstract english

A drilling made in 1972 at Haslov, Scania, southern Sweden, penetrated a 2572 m thick succession of Phanerozoic strata. The only cored parts of the succession derive from the Upper Ordovician and the Furongian (upper Cambrian) series. Merely the uppermost part of the Furongian was recovered, comprising eight metres of Alum Shale with limestone concretions. Nine species and subspecies of trilobites are identified and their succession is used for subdividing the core into the Peltura scarabaeoides Zone, comprising the Parabolina lobata and the Peltura paradoxa subzones, and the Acerocare Zone, comprising the Peltura transiens Subzone. The conodont Cordylodus proavus? was found in the uppermost part of the core. The faunal succession is interrupted by conspicuous unfossiliferous intervals; the most extensive one measuring 3.39 m. Approximately coeval barren intervals have been recorded from other localities in Scania. Although the ecological significance of these intervals remains to be evaluated, it can be concluded that they are a regional feature in the Furongian of Scania.
