Summary:The intrusion of the Peyron diorite into the Velay anatectic granite resulted in the remelting of the latter. Convective movements inside the palingenetic magma divided the dioritic magma into a few large masses and into many small enclaves. During this mingling process, crystal exchanges and chemical diffusion occurred. The resulting hybridization was weak where the thermal disequilibrium between the contiguous magmas was pronounced. Hybridization processes were much more complete where the thermal disequilibrium was weaker, and the dioritic magma crystallized slowly. [M.L.]
