Rock-forming Minerals

Download or read book Rock-forming Minerals written by William Alexander Deer and published by Geological Society of London. This book was released on 1997 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Looking mainly at the amphiboles, this volume has added sections on deerite, howieite and multiple-chain silicates (biopyriboles). This edition includes results of recent research into amphiboles. Each chapter is headed by a brief tabulation of mineral data and a sketch showing optical orientation. Diagrams of the crystal structures are presented and followed by discussion of the structural features, making use of data from spectroscopic and diffraction experiments. The chemical sections include over 550 analyses from which structural formulae have been calculated, illustrating the range of chemical and paragenetic variation exhibited by each mineral. There are results of P-T experiments, thermochemical and computer modelling techniques. The principal modes of occurrence are described in the paragenesis sections emphasizing correlations with chemistry.
