Igneous banding, schlieren and mafic enclaves in calc-alkaline granites : The Budduso pluton (Sardinia)

, 2008
International audienceThis study deals with the origin of igneous layering in plutons, and, especially, the extent layering is related to mafic–silicic magma interactions. The Budduso pluton (Sardinia) shows three main scales of organization.
