Decades of field and microscope studies, and more recent quantitative geochemical analyses have resulted in a vast, and sometimes overwhelming, array of nomenclature and terminology associated with igneous rocks. This book presents a complete classification of igneous rocks based on all the recommendations of the International Union of Geological Sciences (IUGS) Subcommission on the Systematics of Igneous Rocks. The glossary of igneous terms has been fully updated since the first edition and now includes 1637 entries, of which 316 are recommended by the Subcommission. Incorporating a comprehensive bibliography of source references for all the terms included in the glossary, this book is an indispensable reference guide for all geologists studying igneous rocks, either in the field or the laboratory. It presents a standardised and widely accepted naming scheme that will allow geologists to interpret terminology in the primary literature and provide formal names for rock samples based on petrographic analyses. It is also supported by a website with downloadable code for chemical classifications.

Ten years have passed since the last symposium on "Rock Deformation" was held in Los Angeles. The intervening period has seen striking advances in X-ray and experimental structural petrology. The Symposium of the Working Group on X-Ray and Experimental Structural Petrology, held at the invitation of the Deutsche Forschungsgemeinschaft on 17 and 18 February, 1969, in the Mineralogy Institute of the Technische Hochschule Darmstadt, was intended to display the progress made in this field. A meeting on the same had been held in 1968 at the Mineralogy Institute of the Technische Hochschule Aachen. The outcome of many years of effort has been the development of new, automated in struments for the X-ray processing of specimens. The X-ray and optical data so obtained are processed by computer to give complete texture diagrams; it is also possible to rotate the coordinates, and to make an indirect determination of data which have not been measured. In experimental structural petrology, the temperature and pressure dependence of the translational system has been studied in minerals from various types of rock formation which had not previously been investigated, and deductions were made concerning certain mineral parageneses. The original contributions on field findings were conceived and executed so as to point up the possible links with experimental work on structural petrology. They determine for a given mineral facies the pressure and temperature ranges to be applied in experimen tal studies of deformation in single crystals and in rocks.
