Metamorphic rocks contain the record of orogenic processes. Understanding orogeny depends critically on reading the patterns of microstructure and mineral composition in order to constrain metamorphic conditions and their evolution in time and pressure-temperature space. Considerable progress has been achieved through the application of the principles of equilibrium thermodynamics, typified by the widespread use of calculated phase diagrams. However, complete sample-scale equilibration is the exception rather than the rule in most crustal rocks, thermodynamic data are incomplete or imprecise, and interpretation of textural relations is often subjective. We invite contributions from all fields of metamorphic petrology critically assessing the interpretation of metamorphic textures and their implications for determining the P-T-time evolution of rocks, and for interpreting larger-scale geodynamic processes.
