Tuscan Magmatic Province

My work in the Tuscan Magmatic Province started in 1990 when I went on sabbatical to live on the Island of Giglio where my sister Pam has a small vacation house. I connected with Fabrizio Innocenti, a petrology professor at the University of Pisa, and the work continues to this day. Fabrizio served as my mentor up until his death in 2009, but the lessons learned guide me still.

Our work continues, guided principally by Prof. Sergio Rocchi at the geology department in Pisa, with imaginative and rigorous contributions from Andrea Dini at the Council on National Research. Emanuele Roni, PhD student working on emplacement processes and mechanisms, rounds out the active team.

One area of research in which I’m most heavily involved is the study of shallow level intrusions, partially through a loosely affiliated group called LASI. Information for our most recent conference, LASI 4 in Moab, Utah, provides topical information about the conference presentations as well as photo coverage of our two-day field trip to the Henry Mountains. Andrea Dini’s photos for the conference have also been posted. A Program with Abstracts is also available for the conference. My presentation at the conference is temporarily available for review.

Recent Presentation

The LASI V conference will be held in Port Elizabeth, South Africa October 29-30, with a post-conference field trip to the Karoo Basin to see the Golden Valley Sill and other shallowly-emplaced rocks.
