Single-Crystal Study of Biotite-Like Material

Crystal chemistry of biotite-like mica has been investigated by single-crystal X-ray diffraction and microprobe analysis as part of our recent structural study of zeolite-rich rock samples from Donje Jesenje, Croatia. A dark-green prismatic crystal of 0.3 x 0.2 x 0.05 mm^3 in size with no visible inclusions was selected for room-temperature intensity data collection on a Nonius Kappa CCD diffractometer with MnK-alpha radiation (1186 unique reflections, R = 5.1 %). The elemental analysis was carried out on the same crystal using energy-dispersive X-ray spectroscopy (EDXS) in an analytical system TRACOR-Series II, attached to the JEOL (JXA-840A) scanning electron microscope.
