WebGranodiorite is a plutonic igneous rock, formed by intrusion of silica-rich magma, which cools in batholiths or stocks below the Earth's surface. It is usually only exposed at the surface after uplift and erosion have occurred. Etymology [ edit] The name comes from two related rocks to which granodiorite is an intermediate: granite and diorite. WebThe Santa Rosa mylonite zone developed predominantly from a granodiorite protolith in the eastern margin of the Peninsular Ranges batholith. A wide variation in K−Ar biotite dates within the zone is shown to reflect the times of cooling through closure temperatures whose variability is chiefly a result of deformation-induced reduction in grain size. We suggest … Web1. aug 2015 · Granodiorites of the South Mountain Batholith (Nova Scotia, Canada) derived by partial melting of Avalonia granulite rocks beneath the Meguma terrane: Implications … gowerton surgery opening times
