Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS
Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 369-389, June 2026.Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract After assembly, supercontinents are shaped by internal rifting and peripheral subduction. However, the geodynamic relationship between these two processes and their respective contributions to supercontinent breakup remain poorly understood.
