The partition of Si, A1, Ti, Fe 3+, Mg, Fe 2+, Mn, Ca and Na between coexisting Carich and Ca-poor pyroxenes from a wide variety of igneous and metamorphic rocks have been investigated systematically. Many of the distributions, and especially those for the partition of Ti, Mg, Fe 2+, Mn and Na, indi
This paper is an extension of the earlier one dealing with kyanite in which the best fitting value of the oxygen ligand distance for Cr 3+ is adopted to study the spectroscopic properties of Cr 3 + ions doped at the two possible A1 sites in the other two polymorphs of the aluminosilicate group (A120
