The Distinction Between Sn‐Mineralized and Sn‐Barren Granites in Sn Isotopes
Abstract Tin mineralization is commonly associated with highly evolved granites. However, not all highly evolved granitic rocks are mineralized with Sn. Comparative studies of Sn‐fertile and Sn‐barren granites can deepen our understanding of the key processes that lead to Sn enrichment in magmatic‐hydrothermal systems.

Experimental Phase Equilibria Study and Thermodynamic Modeling of the Na2O–SnO–SnO2–SiO2 System
ABSTRACT Integrated experimental and thermodynamic modeling study of the phase equilibria in the Na2O–SnO–SnO2–SiO2 system in air and in equilibrium with liquid metal has been undertaken for characterizing the thermochemistry of slag in smelting side streams enriched in Sn and optimizing the fuming process. New experimental phase equilibria data at 800°
