Abstract
Microanalysis of O isotope ratios has been made in traverses across two garnet crystals and one staurolite sample (all ~1 cm in diameter) from a metapelitic schist and across one garnet sample ~4.5 mm in diameter from an amphibolite from the Cordillera Darwin metamorphic complex, Tierra del Fuego, Chile. The data show that regional metamorphic garnet and staurolite can preserve prograde variations of O isotopes in amphibolite facies terranes. -from Authors
