Relazione sul Workshop «Paleontologia e biostratigrafia dei sedimenti ammonitiferi toarciano-bajociani in successioni di alto morfostrutturale dell' Appennino umbro-marchigiano: l'area di Monte Nerone. Correlazioni con altre regioni della Tetide occidentale». (Piobbico, 2-14 agosto 1993)

Abstract

This report is the synthesis of the field work and discussions held during the workshop «PaIaeontology and biostratigraphy of Toarcian-Bajocian Pelagic Carbonate PIatforms ammonitiferous sediments of umbro-marchean Apennines: the Monte Nerone area. Correlations with other western Tethys regions» (Piobbico, CentraI ItaIy, august 2-14, 1993). It presents a preliminary proposition of biohorizons for rock correlation in the investigated area, following the proposais of Italian Commission on Stratigraphy on definition of biostratigraphic units. The sampied «body of rock strata» consists on 113 beds, 25,60 metres thick, where 30 biostratigraphic surfaces (biohorizons) has been recognized.
