The matrix is composed mainly of serpentine, 3(FeO_<0.3>MgO_<0.7>)・2SiO_2・2H_2O, which is intimately associated with an abundant FeO-NiO-S phase.}, pages = {311--317}, title = {Major Element Composition of Clay Minrals in the Murchison (C2) Carbonaceous Chondrite Matrix}, volume = {17}, year = {1980} }
