The workshop is for graduate students & advanced undergraduate students who want to learn more about the research applications of SIMS in geoscience & related fields. For further information, please contact Beth Ann Bell (ebell21@ucla.edu) or Nozomi Matsuda (nozomi32@ucla.edu).

The UCLA SIMS lab will hold a student workshop on SIMS in geosciences and planetary sciences February 24-27, 2025. Applications are due December 2; instructions and further information available here:

With high spatial resolution for U-Pb and trace element analyses, this study was able to unravel more information about the early history of the HED parent body. Read it here:

The mineral zircon can be dated using the U-Pb system and its trace element composition helps distinguish magmatic processes or metamorphic origins. In HED meteorites, zircons reveal prolonged thermal metamorphism along with many shocked zircons recording impact events.

. using U-Pb radiometric dating & trace elements in tiny zircons in the meteorites. HED meteorites are differentiated meteorites thought to represent the mantle, basaltic crust, & surface regolith of a small parent body from the early solar system, potentially asteroid 4 Vesta.

Recent research highlight: Melanie Barboni & Madeline Marquardt of ASU used UCLA’s ims1290 ion microprobe to put better age constraints on magmatic, metamorphic, and impact events on the parent body of the Howardite-Eucrite-Diogenite (HED) meteorites
