This book is intended for the use of advanced students, research workers, and teachers in the field of petrology. Its aim is to present a unified general impression of the origin and evolution of rocks that are generally believed to have crystallized, or to have been profoundly modified, at high temperatures and at pressures such as prevail from the earth's surface to a depth of perhaps 20 km.

Ignez de Pinho Guimarães and Jefferson Valdemiro de Lima Editorial for Special Issue “Mineral Chemistry of Granitoids: Constraints on Crystallization Conditions and Petrological Evolution”

Jefferson Valdemiro de Lima, Ignez de Pinho Guimarães, José Victor Antunes de Amorim, Caio Cezar Garnier Brainer, Lucilene dos Santos and Adejardo Francisco da Silva Filho A Review of the Mineral Chemistry and Crystallization Conditions of Ediacaran–Cambrian A-Type Granites in the Central Subprovince of the Borborema Province, Northeastern Brazil

A remarkable prehistoric site has recently been excavated tn Yorkshire, known as Paddock Hill, Thwtng or simply Thwtng (National Grid Reference TA 030706). It consists of a later neoltthtc-earlter Bronze Age henge monument that was converted into a hillfort tn the later Bronze Age ( 1200 be). The longevity of occupation, over a millennium, gtves rise to a continuous sequence of ceramics from Grooved Ware and Beaker pottery to post DeverelRimbury ceramics. 
In southern England there ts a twenty-five year tradition of analysing ceramics from archaeological excavations, out Yorkshire ts not so fortunate. The complexities of glacial drift have, to a large extent, precluded the use of thin section petrology, and this project was conceived as an attempt to investigate the feasibility of ustng petrological anafysis to provenance prehistoric pottery in a complex geological area. <...>

We are all familiar with the subdivision of the natural world into the plant, animal, and mineral kingdoms. Of these the realm of minerals is the study and research area of mineralogy. A mineralogist uses the word mineral, however, in a much more restricted sense than prevails with common usage. If we examine a rock rather closely, we notice, for example, that a sandstone is composed of individual quartz grains.

This book is concerned with the study of ores as rocks—that is, with ore petrology. 
For much of the last three hundred years—and certainly for much of the twentieth century—most students of ore genesis have regarded the majority of metalliferous deposits as exotic entities, derived from extraneous sources and superimposed on geological situations to which they bore little or no genetic relationship. Almost the only exceptions have been those, such as ores of chromium and nickel, that have apparently formed as part of the igneous rocks that enclose them.

В пособии сформулированы представления о магмах и причинах разнообразия магматических пород; приведена современная классификация плутонических и вулканических образований; систематизированы сведения о типах метаморфизма и метаморфических пород.

Petrology is a required subject of study in a majority of geology programs in the United States and is an integral part of geology curricula in Canada and elsewhere in the world. The subject merits this important position because rocks make up much of the Earth. Furthermore, many subdisciplines in geology incorporate petrologic knowledge. Thus, petrology provides the foundation for the study of the Earth and its history. 

This book is intended as a reference book, providing extensive information on the applications of coal petrology and the importance of that discipline for characterization of coals in terms of composition and rank, for the assessment of coal quality, and for the prediction of coal properties and behavior during utilization. The book is especially recommended for coal producers, coal marketers, and others associated with the coal industry, as well as for coal researchers and teachers. It provides extensive background information not only on different coal characteristics and properties but also on the way those characteristics determine technological properties.

This chapter introduces rocks and petrology, the science that attempts to explain the origin and distribution of rocks. Rocks are the solid material constituting the Earth, and it is essential to know what composition the planet has. We begin with a brief review of the planetary formation process and how it determined the Earth’s composition and major divisions into core and mantle.
