Rock-Forming Minerals: Disilicates and Ring Silicates, Volume 1BWilliam Alexander Deer, Robert Andrew Howie, J. Zussman Geological Society of London, 1997 - 629 pages This part deals mainly with the disilicates and ring silicates including the epidote, melilite, cordierite and tourmaline groups. In addition to the minerals dealt with in the first edition, some of the rarer but typical minerals in the calc-silicate rocks and the accessory minerals of nepheline-syenites and related rocks have been included. The orthosilicates, in particular the olivine, garnet and humite groups are covered in Volume 1A. |
