- Abstract
The crystal structure of the original natural gugiaite, Ca2BeSi2O7, from the skarn rocks in the Gugia alkaline complex, Liaoning Province, China, is determined from CCD data in space group P4¯21 m, a = 7.4330(10), c = 4.9970(10)A°, V = 276.08(8) A°3, Z = 2. The structure is basically consistent with that of the synthetic one, although there are longer Be-O distances, smaller distortions of BeO4 tetrahedron and larger distortions of SiO4 tetrahedron than those in synthetic one.
