Emplacement of the lyngdal granodiorite (SW Norway) at the brittle-ductile transition in a hot crust.

Abstract : The 1.0–0.9 Ga plutons of the HBG suite (Hornblende-Biotite Granitoids) associated with the Rogaland anorthosites belong to the Sveconorwegian post-collisional magmatism in southwestern Norway. The comparison between experimental and natural phase equilibria indicates that the Lyngdal granodiorite (HBG suite) crystallized between 4 and 2 kbar, the magma having 6 wt% H2O in melt at early stages and an fO2 in the range NNO/NNO+1 (Bogaerts et al., 2002).
