Different hypotheses exist on the origin of native copper mineralization in the Parana volcanic province that invoke magmatic, late magmatic, or hydrothermal events. The average copper content in the host basalts is ~200 ppm. Native copper occurs as

Solid-state 17 O NMR measurements between room temperature and 973 K were performed for the first time on 17 O-enriched yttria-stabilized zirconia samples. Spin–lattice relaxation is found to exhibit a strong temperature dependence which can be tra
