A popular model for the emplacement of roughly spherical plutons is that of "ballooning' or in situ inflation of a magma chamber. Reexamination of three supposedly ballooned plutons (Ardara, Ireland; Cannibal Creek, Australia; Papoose Flat, California) and evaluation of published descriptions of many others indicate that this model is largely incorrect. Many plutons previously interpreted as post-tectonic ballooning plutons are better viewed as syntectonic, nested diapirs emplaced by a variety of country-rock material-transfer processes. -from Authors
