Mount stuart batholith
NettetThe Mount Stuart batholith of the Washington Cascades is offered as an example of high-temperature infiltration of high δ 18 O fluids derived from its contact aureole. Some of the fluid infiltration coincided with and may have been partly derived from a kyanite-grade, post-emplacement metamorphic event that affected northern portions of the batholith.
