Overview

New insights on U-Pb ages and Nd isotopes reveal magma mixing in mafic magmatic enclaves and granodiorites.

Key Points

  • Titanite cores in the mafic magmatic enclaves show εNd(t) ranging from −2.5 to −3.4, indicating mixed magmas.
  • Analysis reveals distinct textural and chemical differences in titanite between enclaves and granodiorite, supporting magma mixing hypotheses.
  • Thermobarometric data suggest that crystallization temperatures for amphibole in enclaves were around 788 °C—higher than granodiorite crystallization.
  • The findings imply that mixed magmas influenced the formation of titanite, offering deeper insights into Triassic granitic magmatism.
