Abstract We show from elastic neutron diffraction data that anorthite CaAl2Si2O8 (An100) undergoes a primitive to body-centered phase transition at T c =237±1°C. The transition is reversible, and T c is well defined. Our measurements demonstrate that the I-lattice at the high temperature phase applies to all structural elements; in other words, the time-averaged lattice is exactly body-centered and not just in the space average of An100, as concluded earlier by other authors.
