Inferred Depths of Formation of Spinel Cataclasites and Troctolitic Granulite, 76535 Using New Thermodynamic Data for Cr-Spinel
Abstract
New thermodynamic calculations of equilibria pertinent to spinel cataclasites and troctolites reveal that these assemblages formed at depths <25 km (cataclasites) and >45 km (troctolites). Calculations also suggest that symplectite textures formed from trapped melt.
