Abstract

The crystal structures of five monoclinic alkali amphiboles from Kajlidongri, Madhya Pradesh, India, have been refined to R indices of << 2% using approximately 1100 observed (5Sigma ) reflections measured with Mo-Kalpha X-radiation; the crystals used in the collection of the X-ray data were subsequently analysed by EPMA. Both site-scattering refinement and an ion microprobe analysis show major Li in these crystals. The crystal chemistry of (super [6]) Li incorporation in alkali amphiboles, together with the structural constraints that control ordering behaviour and possible chemical variations are examined.
