I have several specimens that contain millimeter-sized mafic magmatic enclaves hosted by centimeter-sized mafic magmatic enclave in granodiorite and want to know their genesis.

Some mafic inclusions occur when mafic dike intrudes more felsic mostly frozen magma. The dike is disrupted by mostly solid flow in the host body. Other enclaves involve magma mingling. Repeated events should provide multiple hosting.
