What we are....



The Sierra Nevada...Alan's country

The measurement of "cosmogenic" nuclides has revolutionized the study of Earth Surface processes giving us a means by which to measure the age of some landforms and the rate at which others change over time. UVM now has one of only a handful of laboratories in the country dedicated to the preparation of samples for analysis of 10-Be and 26-Al, two of the most useful of these nuclides.


 

Our laboratory is located on the third floor of Delehanty Hall; it is brand new as of Fall 2004. The lab is directed by Paul Bierman with Jennifer Larsen doing technical work. The lab has four fully exhausting laminar flow hoods, an acid recapture system and all the centrifuges and Teflon wear necessary to separate microgram quantities of Be and Al from 20-60 g of purified quartz. We do most of our rock torture and isolation of a pure quartz fraction in a mineral separation lab isolated from our clean sample preparation space.



 

   

In order to make isotopic measurements, we work extensively with collaborators at Lawrence Livermore (CAMS) National Laboratory and at Purdue University (PRIME). Since its inception in late 1993, the lab has housed a technician and three students. We have processed over 500 samples and prepared over 800 targets for analysis.
