Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes. Apatites from the Early Cretaceous Sanguliu granite and its MMEs in the Liaodong Peninsula exhibit pronounced compositional heterogeneities. In this study,

Supergiant porphyry copper deposits are failed large eruptions
, 2022 Porphyry copper deposits, the principal source of copper and molybdenum, form at convergent margins. Copper is precipitated from fluids associated with cooling magmas that have formed in the mantle and evolved at mid- to lower crustal levels, before ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.
