Front Cover
Spectacular view of the Geisler mountain group in the Dolomites area of northern Italy, wherefrom, in 1892,A. Bittner from the Vienna Geological Survey derived the stage name ¡°Ladinian¡±. The thick platfom carbonates forming the bright peaks and cliffs of the Geisler mountains are laterally replaced by coeval basinal carbonates of the Buchenstein Formation visible in the foreground. The fossiliferous pelagic strata follow on top of an older,cliff-forming and dolomitised thin platform, and the basinal beds are interbedded with thin volcaniclastic layers.At Seceda two of these layers have yielded precise U-Pb-zircon ages with values around 241 and 238 Ma for levels in the lower and in the upper part of the section respectively. The Buchenstein Formation at Seceda is the principal auxiliary section to the GSSP-section at Bagolino elsewhere in the Southern Alps of northern Italy. The base of the Ladinian Stage is located within a nodular limestone unit, at an altitude of approximately one fourth above the base of the pelagic succession as visible on the photo.
