The article illustrates the scientific results of a stratigraphic core drilled thorugh the entire Buchenstein-Livinallongo Formation at Seceda, Groedner Tall-Val Gardena, Northern Dolomites.

Abstract

The article illustrates the scientific results of a stratigraphic core drilled thorugh the entire Buchenstein-Livinallongo Formation at Seceda, Groedner Tall-Val Gardena, Northern Dolomites. The succession is formed by basinal beds, late Anisian and early Anisian in age. The lower units consists of organic rich laminated sediments (Plattenkalke) providing an example of potential source level for hydrocarbon. The following unit is formed by nodular cherty limestones (Knollenkalke), with subordinated volcanogenic intercalation of acidic ashes (Pietra Verde) important for their bearing zircon crystals suitable for isotopic dating. The upper unit consist of laminated micrites, resedimented calcarenites and marls (Baenderkalke). The succession is valuable for its providing an example of basinal sedimentary cyclicity and for its high correlation potential.
