Biography

"Sandro" was born in Ancona, July 25, 1954. In 1968, at the age of 14, he joined the Marche Speleological Group GSM-CAI of Ancona and participated in expeditions at Frasassi and in other karstic localities of the Umbria-Marche Apennines, where he conducted research in the fields of stratigraphic geology, paleoclimate, and neotectonics.

He obtained his Laurea degree in geology at the University of Urbino in 1979. Shortly afterwards he moved to the United States where, in 1986, he received his Ph.D. at the University of California in Berkeley.

In 1992, he returned to Italy with his family, near the town of Apiro, inland of his birthplace of Ancona, in the Marche region of central Italy, in a semi-abandoned hilltop hamlet called Coldigioco.

He lives in Coldigioco with his wife Paula Metallo, an artist from Syracuse, USA, and has two children Fiorenza and Maxwell.

Osservatorio Geologico di Coldigioco

Walter Alvarez, with the support of Sandro Montanari (centre front), helped to organize a meeting of Big Historians at the Geological Observatory at Coldigioco in Italy in 2010 which resulted in the establishment of the International Big History Association.

Alesandro Montanari is the director of the Geological Observatory of Coldigioco, near Ancona, in the Marche region of Italy. It is in the Apennine mountains of central Italy.

The Osservatorio Geologico di Coldigioco (OGC) is an independent center for research and education in geology, art, and cuisine. Located in the beautiful, tiny hilltop village of Coldigioco in the Apennine mountains of central Italy, OGC consists of sleeping, eating, and living facilities, geological labs, art studios, kitchens, and a small fleet of vehicles. Sandro Montanari and Paula Metallo run OGC with assistance from friends and colleagues from the U.S.A. and Europe.

A considerable number of Geoscientists have collaborated with Sandro over many years, including:

• Walter Alvarez, University of California, Berkeley
• Dave Bice, Penn State University
• Christian Koeberl, University of Vienna
• Jan Smit (paleontologist), Free University of Amsterdam
• Jenn Macalady, Penn State University
• Greg Druschel, University of Vermont

Academic Achievements

By 2023 Alessandro Montanari had published over 150 peer-reviewed scientific papers, written, edited, or co-edited several books, and has received several distinctions, including the European Geosciences Union Jan Baptiste Lamark Medal, 2007; Fellow of the Geological Society of America, 2010; Marie Curie Fellowship 2010 from the European Commission. In 2010 he was elected a Corresponding Member of the Austrian Academy of Sciences.

Montanari’s contributions to stratigraphy are numerous and important. He made a systematic effort to attach numerical ages to the subdivisions of the Early Tertiary by dating air-fall volcanic crystals in Umbria-Marche pelagic carbonates. His work showed that there had been only one single, large impact at the KT boundary. His team discovered evidence for multiple impact events in the rocks just below the Eocene-Oligocene boundary, later connected with Popigai in Siberia and Chesapeake in the US. He was one of the leaders of the stratigraphic research that led to Massignano, near Ancona, being selected as the global type section for the Eocene- Oligocene boundary. He has studied the stratigraphy of the Late Eocene and the Eocene- Oligocene boundary for more than 20 years and has made very important contributions to this area of research. With Farley and Shoemaker, Montanari pioneered the use of helium isotopic measurements thus documenting a comet shower in the late Eocene.

Subsequently he has been involved in research aimed at establishing the GSSP for the Rupelian-Chattian and base-Tortonian sections. Montanari has done stratigraphic field studies in a number of places outside Italy, most notably in Mexico, where he was part of the team that discovered impact ejecta precisely at the KT boundary in stratigraphic sections only a few hundred km from the Chicxulub crater, thus demonstrating that that crater dates from exactly the time of the KT mass extinction.
