S U M MARY. Comparison of the infrared spectra (4oo0-50 cm -1) of natural and synthetic samples of margarite, beryllian margaritc, ephesite, and clintonite indicates that the tetrahedral layers of margarite and ephcsite, containing Si and AI in equal atomic proportions, are ordered as the spectra are sharp and show no A1--O-AI vibrations. Clintonite of this tctrahedral composition is disordered. The hydroxyl-stretching frequencies are affected by ionic substitutions in both the octahedral and… CONTINUE READING
