Key Points

  • To introduce Cat-87 clinopyroxene as a new reference material for oxygen isotope microanalysis and assess its applicability.
  • Introduced a new reference material named Cat-87 clinopyroxene.
  • Conducted in situ oxygen isotope analysis.
  • Tested its performance across various Ca-Mg-Fe clinopyroxene compositions.
  • Validated Cat-87's utility in oxygen isotope microanalysis.
  • Demonstrated improved analytical accuracy compared to bulk methods.

Abstract

Clinopyroxene oxygen isotope compositions provide critical insights into diverse geological processes. In situ oxygen isotope analysis is preferred over bulk methods because of complications such as inclusions, alteration, and isotope...
