✦ Synopsis

of Geology and Geotechnics, V Holegovi(k(zch An X-ray diffraction analysis was performed on a single crystal of natural orthorhombic analcime: (Nao.s6Ko.o6 Cao.os) [(AI0.ssFeomSi2.osTio.ol)O6]-1.12 H20; Ibca: a = 13.720(2) A, b = 13.715(2) /~, c = 13.709(1)/~; V = 2579.8/~3; Z = 16 (locality: Vl6f Hora, Bohemia). Refinement of 1340 independent reflections yields R = 0.032. The mean Si(AI)-0 distance is 1.6467 /~, and the angle is 109.49 °. The framework of orthorhombic analcime is topologically the same as cubic modification.
