Summary High temperature fault zones in the Valle d’Ossola region of the Ivrea zone in northern Italy appear to accommodate extension of the deep crustal section. 40Ar-39Ar age spectra indicate that this extensional event occurred prior to 280 Ma, and initiated a period of crustal thinning and cooling. Interpretation of the closure temperature in this system is dependent on grain size and cooling rate.
