Combined Nd and Sr isotope data for the Hercynian granites of SW England provide important new evidence for the origin of the Cornubian batholith. The Nd isotope systematics are shown to be robust even in areas of extensive hydrothermal alteration. ENd values for the main plutons range from −4.7 to −7.1 whereas values for the Palaeozoic country rocks are significantly lower, typically –8 to –11. Depleted mantle Nd model ages (1.3–1.8 Ga) indicate a heterogeneous source region for the granite…

The Cornubian Batholith: an Example of Magmatic Fractionation on a Crustal Scale

Abstract. The Cornubian Batholith comprises six major and several smaller bodies of S‐type granite in southwestern England. These late‐Variscan granites comprise two‐mica granites, and much less

An Rb-Sr study of Hercynian magmatism in SW England has established that the major granites were emplaced c. 290–280 Ma and that the inferred sequence of intrusion shows no geographic pattern. High

Abstract Permian basic/ultrabasic lavas from south-west England may be divided into a ‘basaltic’ and a K-rich group. Both groups have enrichment of large-ion lithophile (LIL) elements relative to
