Penrose-logoDuring 25 and 29 September 2017 the Geological Observatory of Coldigioco (OGC) Apiro, Marche Region, Italy will celebrate 25 Years of existence during the conference: 250 Million Years of Earth History in Central Italy. The conference is organized under the auspicies of Geological Society of America by Alessandro Montanari, director of OGC and Christian Koeberl from University of Vienna in the Teatro Mestica di Apiro.

Osservatorio Geologico di Coldigioco (OGC), Apiro, Italy

Located in the beautiful, tiny hilltop village of Coldigioco in the Apennine mountains of central Italy, OGC is an independent research and educational center, which was founded in an abandoned medieval hamlet near Apiro in 1992 by Alessandro Montanari, Walter Alvarez, and David Bice.

The objective of this conference is to present an updated vision of 250 million years of earth history as recorded in the sedimentary succession of the northern Apennine orogeny in central Italy. At the conference, besides keynote review presentations, original research works will be presented covering specific subjects of Tectonics and Structural Geology, Integrated Stratigraphy and Astronomical Tuning, Extraterrestrial Event Stratigraphy, and Quaternary Geology and Geo-Bio Speleology. These research works are either still in progress or they were accomplished but never published before, all with the support of the Geological Observatory of Coldigioco.

The program of the conference includes sessions on:

  • Tectono-structural Evolution of the Northern Apennines Accretionary Wedge
  • Jurassic to Miocene Integrated Stratigraphy and Astronomical Tuning
  • Extraterrestrial Event Stratigraphy
  • Quaternary Sciences and Geo-Bio Speleology

The Geo-Bio Speleology session include one presentation of our results after some years of work in Frasassi Cave system entitled Mid-Pleistocene to Recent ostracod record in slack water deposits of the Frasassi gorge and cave system as a prospective proxy for palaeoenvironmental reconstruction (Tadeusz Namiotko, Sanda Iepure, Alessandro Montanari). We studied several sequences of  slack water deposits collected from both caves in the Frasassi area and river banks of Sentino River, representing various time windows from lower Middle Pleistocene to Holocene, and allowing comparison with the modern ostracod assemblages in Sentino.
