Abstract
The crystal structure of the natural high-manganese tinzenite of the axinite group has been refined. Using precision X-ray diffraction data, the fine details of the “isomorphous ratios” for atoms occupying the cationic positions were revealed. The final structural formula of the mineral is determined as (Mn0.88Mg0.03Fe0.09)(Ca0.925Mn0.075) (Ca0.495Mn0.505)(Al0.9Fe0.1)(Al0.98Fe0.02)[BSi4O15](OH). Examination of the isomorphous ratios provided the refinement of the classification of the axinite group.
