Ekaterinburg For each mine we calculated the medium value of lattice parameter. For each mine we calculated the medium value of chemical analyses (analysed 20 point ) by EMPA (Cameca CX 827). Mn, Se, F, Rb are under detection limits except in few cases. Li and Be are not determined. Chemical analyses have been normalized at 85%.      H2O was determined by EA 1108 Carlo Erba (gas cromatographer).
