Marian – the pre-Alpine Sondalo gabbroic complex in the Italian Central-Eastern Alps occupies an area of about 35 km2 and it is mostly amphibole-gabbro. You may have a look at R. Tribuzio, M.F. Thirlwall, B. Messiga, Contrib Mineral Petrol (1999) 136: 48-62 These two papers deal with the country rocks Braga, R., Callegari, A., Messiga, B., Ottolini, L., Renna, M.R., Tribuzio R., 2003. European Journal of Mineralogy, 15, 393-400. Braga, R., Giacomini, F., Messiga, B., Tribuzio, R., 2001. Physics and Chemistry of the Earth, (part A), 26, 333-342.
