| During Early Cretaceous times, there was a significant period of plutonism and crustal growth in the magmatic arc. |
| A similar inter-relationship between strikeslip faulting and plutonism was suggested for the Mesozoic batholith of California. |
| In the Antarctic Peninsula, an early Jurassic gap in intrusive activity was followed by widespread mid-Jurassic silicic plutonism in eastern Graham Land. |
| During the mid-Cretaceous a phase of plutonism in Palmer Land caused uplift and erosion that supplied sediment from the arc. |
| Anns Leucogranite has yielded a younger, Cambrian age using the Rb-Sr isochron method and may represent a later phase of plutonism. |
