GSECARS Outreach

GSECARS is a national user facility
for frontier research in the earth sciences using synchrotron radiation at the
Advanced Photon Source, Argonne National Laboratory.

GSECARS provides earth scientists with access to the high-brilliance hard x-rays from this third-generation synchrotron light source. All principal synchrotron-based analytical techniques in demand by earth scientists are being brought to bear on earth science problems:

  • High-pressure/high-temperature crystallography and spectroscopy using the diamond anvil cell
  • High-pressure/high-temperature crystallography and imaging using the large-volume press
  • Powder, single crystal and interface diffraction
  • Inelastic x-ray scattering
  • X-ray absorption fine structure spectroscopy
  • X-ray fluorescence microprobe analysis
  • Microtomograph

Science Highlights

Work at 13 IDE (APS) and X26 (NSLS) looked at identification of new brachinite-like achondrites with implications for the diversity and petrogensis of the brachinite clan


Combined three‐element X‐ray map of section MIL 090206,5. Red = Mg, green = Ca, blue = Al. Olivine = red; augite = bright green; chromite = bright blue; plagioclase (plag) = cyan; orthopyroxene = yellowish green. Top part of section is dominated by single oikocryst of orthopyroxene containing rounded chadocrysts of olivine, chromite, augite, sulfide (sulf), and metal. Plagioclase is concentrated only in lower right of section.                 

Conclusion : Brachinites and brachinite-like achondrites share a common Fe-Mn-Mg redox trend (Fig. 6a) that is distinct from the Fe-Mn-Mg redox trends of ureilites, lodranites/acapulcoites, or winonaites, and have higher olivine Fe/Mg ratio (lower Fo) than these other primitive achondrite groups. This observation suggests that brachinites and brachinite-like achondrites are derived from a common nebular reservoir, which had homogeneous Mn/Mg ratio and was relatively oxidized. We suggest that brachinites and brachinite-like achondrites be collectively called the brachinite clan. Nevertheless, these meteorites are diverse in petrologic features and oxygen isotope compositions (even among the brachinites alone), with no correlations between Δ17O and petrologic features such as texture (granoblastic versus poikilitic), Fo of olivine, modal abundance of plagioclase or pyroxenes, or the presence of grain boundary orthopyroxene+opaques assemblages. Thus, it has been suggested that they represent more than one parent body (Rumble et al. 2008; Day et al. 2012; Greenwood et al. 2012).
