Rock (and fossils) of Ages

Assistant scientist Alison Shaw at work using the ion microprobe, part of the Northeast National Ion Microprobe Facility (NENIMF) at WHOI. The facility is one of the National Ion Microprobe Facilities supported by the National Science Foundation (NSF) in the United States. The ion microprobe extracts information from rocks about when, where, and how they formed, and from fossils about environmental conditions in the geologic past.
