The Baw Baw massif consists of a late Devonian granodiorite pluton. Ore formation occurred with the intrusion of the Butte quartz monzonite pluton. Farther east, and deeper, the sills coalesce into a deeply buried granodiorite pluton. A considerable gravity anomaly is associated with the Dartmoor pluton as with other such plutons. Igneous minerals within a pluton can record deformation history. Stone Mountain is a pluton, a type of igneous intrusion. In other literature, batholith and pluton have been used interchangeably. The outer zone of the pluton consists of two alternating mafic hybrid rock types. In practice the term pluton most often means a non-tabular igneous intrusive body. These basalts were intruded by a pluton shortly after their eruption. The Foxdale granite pluton was also emplaced at this time. Adamellite intruded, named Mount Pearson Pluton and feeding the St Marys Porphyrite at . Rolesville is the namesake of the Rolesville diorite Batholith, also known as the Rolesville Pluton. Eventually the overlying strata were removed through erosion, exposing the granite pluton. Mineralization and ore continue into the pluton.
