Description:
The crystal structure of axinite, H(Fe,Mn)CaThe most noteworthy features of the axinite structure include: (1) the BThe distortions of the Si tetrahedra in axinite are examined by plots of tetrahedral-edge length versus the mean Si–O distances of the two oxygen atoms of the edge. The edges between bridge and nonbridge oxygen atoms were found to be invariably the shortest. Similar charts were prepared for several pyrosilicates, pyroxenoids, clinopyroxenes and clinoamphiboles. The relationship between the ratios of (O–O):(Si–O) length and types of oxygen is discussed as measures of tetrahedral distortion.
