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. Photo courtesy Peter Brack, ETH
