Tim Dooley coauthored a report on the NSF-Funded Second Workshop on "Analog Modeling of Tectonic Processes”, that was held at the Bureau of Economic Geology in May 2017. Almost 50 analog and numerical modelers gathered for this workshop to discuss new techniques, boundary conditions, new materials, and ways to strengthen the analog modeling community. Attendees listened to 10 invited speakers and presented posters and teaching materials over the course of 2.5 days. Tim set up and ran a physical model of an extensional rift system during the workshop. Physical model results were compared to numerical models of crustal extension.

Frank Peel recently spent some time in the field looking at evaporite tectonics in the internal French Alps. In the picture at the left, Frank is standing in front of a gypsum diapir exposed in the Col du Souffre, Vanoise, France. The Triassic salt in the diapir is piercing upward into older Carboniferous strata, as a consequence of being on the overturned limb of an Alpine fold.
