resorption The partial fusion of a euhedral phenocryst in a magma in response to a change in magma temperature, pressure, and/or composition. If the magma is erupted rapidly the partially fused phenocryst can be preserved as a large, anhedral crystal with a lobate outline set in a fine-grained groundmass.
