Recent Stanford graduate Dr. Tom Benson discusses his research on public radio's Science Friday show. Listen to it here: "for a volcanic prediction gaze into the crystalline debris"

Tom's paper on Li in melt inclusions from supervolcano magmas was published in Nature Communications: "Lithium enrichment in intracontinental rhyolite magmas leads to Li deposits in caldera basins"

In a new paper published in Nature Communications, SHRIMP lab member Seth Burgess uses U-Pb geochronology to figure out what triggered the end-Permian mass extinction. More info here:

All U-Th-Pb and trace element data produced by SHRIMP-RG that has been reduced in SQUID-1 or SQUID-2 is now suitable for upload to This is important for data management, archiving, and optional release of data acquired during NSF-supported research. Please download the instructions for online submission here.

To request for instrument time on SHRIMP-RG, please click on the 'Request Form' on the banner. Currently, we are scheduling 3 to 4 months in advance.


New upgrades to the SHRIMP-RG magnet, software, and hardware occurred during April, 2015. This improvement has enhanced magnet stability and allows higher resolution mass scans that improve our ability to distinguish interfering peaks in the mass spectra, particularily at low mass.
