Platinum and Pd-arsenides, antimonides, tellurides, bismuthinides, and sulfides are the major hosts of Pt and Pd in magmatic and hydrothermal Cu-Ni-sulfide ores. Textural relationships among such minerals in nature often provide contradictory message

Kyshtymites are the unique corundum-blue sapphire-bearing variety of anorthosites of debatable geological origin found in the Ilmenogorsky-Vishnevogorsky complex (IVC) in the South Urals, Russia. Their mineral association includes corundum-sapphire,

Xenocrysts in magmatic rocks are often found having gradients in their composition. These compositional gradients are commonly interpreted as the result of mass fractionation during crystal growth and it is quite common that these gradients are also

Besides H2O, CO2 and sulphur, halogens (F, Cl, Br, I) are important volatile components in magmas. The extremely high chemical activity of halogens in melts and liquids leads to a significant influence on (a) magmatic properties, (b) the degassing of

Magma mixing is a widespread magmagenic process. However, its significance in the formation of ultrapotassic magmas has been largely overlooked so far as they are commonly thought to originate directly from the mantle and ascend rapidly through the c

The genesis of high-grade massive Fe-Ti oxide ores (up to >90 vol.%) in layered intrusions remains highly debated. Based on in-situ iron isotope data (δ56Fe) on drill-core samples from Fe-Ti oxide deposit hosted in Hongge layered intrusion, here we

The geochemistry of lavas combined with textural constraints can provide important information on magmatic processes occurring at inaccessible depths. Here we carry out a detailed textural and geochemical study on 0.23 Ma contemporaneous and adjacent
