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.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The PhD thesis at hand consists of three parts and describes the petrogenetic evolution of Uralian-Alaskan-type mafic ultramafic complexes in the Ural Mountains, Russia. Uralian-Alaskan-type mafic-ultramafic complexes are recognized as a distinct class of intrusions. Characteristic petrologic features are the concentric zonation of a central dunite body grading outward into wehrlite, clinopyroxenite and gabbro, the absence of orthopyroxene and frequently occurring platinum group element (PGE) mineralization. In addition, the presence of ferric iron-rich spinel discriminates Uralian-Alaskan-type complexes from most other mafic ultramafic rock assemblages. The studied Uralian-Alaskan-type complexes (Nizhnii Tagil, Kytlym and Svetley Bor) belong to the southern part of a 900 km long, N- -trending chain of similar intrusions between the Main Uralian Fault to the west and the Serov-Mauk Fault to the east. The first chapter of this thesis studies the evolution of the ultramafic rocks tracing the compositional variations of rock forming and accessory minerals. The comparison of the chemical composition of olivine, clinopyroxene and chromian spinel from the Urals with data from other localities indicates that they are unique intrusions having a characteristic spinel and clinopyroxene chemistry. Laser ablation-ICPMS (LA-ICPMS) analyses of trace element concentrations in clinopyroxene are used to calculate the composition of their parental melt which is characterized by enriched LREE (0.5-5.2 prim. mantle) and other highly incompatible elements (U, Th, Ba, Rb) relative to the HREE (0.25-2.0 prim. mantle). A subduction-related geotectonic setting is indicated by a positive anomaly for Sr and negative anomalies for Ti, Zr and Hf. The mineral compositions monitor the evolution of the parental magmas and decipher differences between the studied complexes. In addition, the observed variation in LREE/HREE (for example La/Lu = 2-24) can be best explained with the model of an episod.
