Electron Microprobe Facility - Projects

The Meteoritics and Cosmochemistry group in HIGP use the electron microprobe a lot to prepare for SIMS (ion probe) work. They study meteorites and lunar samples, as well as experimentally prepared samples. Click here for more info on the HIGP webpage.

 

1a. Primitive meteorites

(Sasha Krot, Gary Huss, Kazu Nagashima and co-workers)

Primitive meteorites contain the building blocks of our Solar System. The chondrule below contains normally zoned olivines ranging from pure forsterite (dark) to nearly pure fayalite. The boundary between the original forsterite and the fayalitic overgrowth is diffuse, but the original boundary is still very visible in slower diffusing elements such as phosphorus and chromium.

 

1b. Igneous Meteorites

(Jeff Taylor, Ed Scott*, Klaus Keil*, Julia Hammer, and co-workers)

 

1c. Water on the Moon
