Bottaccione Gorge Geosite

Title: Bottaccione Gorge Geosite
Description: The section is a global reference succession for bio-and magnetostratigraphy across the Cretaceous and Paleogene, including the K-Pg boundary. Here pelagic limestones were first dated with foraminifera in thin section, long-section magnetic polarity-reversal stratigraphy was first established, and the K-Pg iridium anomaly first detected.
Geosite element: K/T clay level
Lithology: limestone; clay; also scaglia rossa (P)
Older named age: Cretaceous
Younger named age: Paleocene
Interest: Historical; Stratigraphic
