Papoose Flat pluton: forceful expansion or postemplacement deformation?

Intense solid-state deformation in the margin of the Papoose Flat pluton, White Mountains, California, and severe attenuation of nearby wall rocks encouraged earlier workers to suggest that this pluton was emplaced by blistering or in situ radial expansion. Reexamination of the pluton and wall rocks indicates that many features present in and around the pluton are not compatible with this model. It is inferred that the Papoose Flat pluton, and other plutons in the White and Inyo mountains, expanded in a western direction. It is suggested that significant Cretaceous regional deformation occurred during and after emplacement of these plutons. -after Authors
