Silicic rocks in the Somoncura region of Argentina, with Daniel Gregori, Ernesto Bjerg, and numerous students (Universidad Nacional del Sur in Bahia Blanca, and CONICET).
Extensive silicic magmatism in South America can not be directly attributed to subduction and arc formation. The Somoncura Magmatic Belt in northern Patagonia, Argentina, a suite of intrusive and extrusive silicic units, is an example of such an area with an equivocal genesis.
This NSF-funded work has been carried out with Daniel Gregori, Ernesto Bjerg, and a graduate student at the Universidad Nacional del Sur in Bahia Blanca (Argentina), undergraduate students at North Dakota State University (Fargo), in cooperation with Clark Johnson and Brian Beard at the Radiogenic Isotope Laboratory at the University of Wisconsin-Madison; Karl Wirth at the Department of Geology at Macalester College (St. Paul, Minnesota); George Gehrels at the University of Arizona; and Jeff Vervoort at Washington State University.

Electric Pulse Disaggregation (Paul Weiblen, University of Minnesota)
The feasibility of pulsed power as a rock disaggegation method. This method is known as pulsed power disaggregation (PPD), electric pulse disaggregation (EPD) and electric pulse fragmentation (EPF). For examples of minerals and microfossils separated using pulsed power technology, click here. Rudashevsky et al 1995.
We were the first to separate fossils from their matrix using pulsed power. Saini-Eidukat et al 1995; Saini-Eidukat and Weiblen 1996.
