A Study on the Chromian Tremolite from Guleman, Elazığ
Chemical composition, optical properties, D.T.A. curve, unit cell dimensions and indexed powder diffraction pattern of the chromium-rich tremolite from Guleman District are given. The chemical composition of this mineral is much more close to the chemical composition of hornblende. It contains 2.97...

| description | Chemical composition, optical properties, D.T.A. curve, unit cell dimensions and indexed powder diffraction pattern of the chromium-rich tremolite from Guleman District are given. The chemical composition of this mineral is much more close to the chemical composition of hornblende. It contains 2.97 % Cr2O3 . Optical properties are obtained as: g=1.632, b=1.623, a= 1.615 all + 0.002 2V=90° ZlC=33°. Unit cell dimensions are: a=9.819 A°, b= 18.084 A°, c=5.200 A°, 104°40' V=893.44 A°3 c Dimension of this mineral is smaller than those found in tremolite and other hornblendes. Exothermic reaction at 830°C found for tremolite is not seen at D.T.A. curve of chromian tremolite from Guleman. |
