... ) and breyite (CaCa 2 Si 3 O 9 ). So far, no solid solutions involving the Ca 1 and Ca 2 sites have been described. Therefore, root names depend on the composition of the Ca 3 site only. Isomorphic replacement at the Ca 3 sites has been noted. We here report data on a skarn sample from the Jakobsberg Mn–Fe...
