The use of computers as primary tools for carrying out geological research and databases for storing geological information has grown considerably in recent years. In the same period there has been a dramatic increase in the degree of collaboration between scientific institutions, universities and industry, and between geologists working in different countries. To facilitate collaborative work amongst geologists and to maximise efficiency in the use of geological databases a common approach to classifying and naming rocks is essential. This publication presents a scheme for the classification and nomenclature of igneous rocks that is practical, logical, systematic, hierarchical and uses clearly defined, unambiguous rock names.

Orogens in space and time are the potential sources of information in understanding the mechanism of episodic global material circulation on a whole-mantle-scale. They represent the hallmarks of the interaction among lithospheric plates. The word “orogen” is derived from Greece (oros for “mountain,” genesis for origin). The term “orogen” or “orogenic belt” has been traditionally described as a mountain belt composed of different types of rocks or rock strata forming a complex of variable size, typically tens to hundreds of kilometres wide and several thousand kilometre long, later fragmented during younger geological time due to various processes (e.g., Miashiro, 1961). In modern terminology, an orogen can be defined as a major linear deformed zone, sandwiched between cratons with prolonged deformational history, repeatedly reactivated and associated with different events of magmatic pulses and metamorphic episodes in space and time (Dewey and Bird, 1970). An orogen or orogenic belt develops when a continental plate crumples and is pushed upwards to form one or multiple mountain ranges. This involves a series of geological processes called “orogenesis.” <...>

Microscopy is a servant of all the sciences, and the microscopic examination of minerals is an important technique which should be mastered by all students of geology early in their careers. Advanced modern textbooks on both optics and mineralogy are available, and our intention is not that this new textbook should replace these but that it should serve as an introductory text or a first stepping-stone to the study of optical mineralogy. The present text has been written with full awareness that it will probably be used as a laboratory handbook, serving as a quick reference to the properties of minerals, but nevertheless care has been taken to present a systematic explanation of the use of the microscope as well as theoretical aspects of optical mineralogy. The book is therefore suitable for the novice either studying as an individual or participating in classwork. <...> 

Migmatites are spectacular, complex-looking rocks that can inspire, fascinate, or confuse geologists. All migmatites viewed in an outcrop represent the sum of a series of processes that acted in parallel, or sequentially, and the influence of various local factors (see the photographs in section A). In order to begin to understand the complexity and seemingly endless variety in migmatites, and to provide the reader context for the subject of this book, some of the key factors and processes that make individual migmatites the way they are should be outlined at the outset <...>

The term geology is a combination of two Greek expressions: “Geo” refers to the Earth, and “logos” refers to the logic and language used to explain your observations. So think of geology as a way to organize and explain the Earth processes that we see all around us. For some of the strange shapes we see, an educated explanation would be great. Most of what we know is good guesswork, based on lab experiments and inferences that take many detailed drawings to explain and a lifetime to understand. Fortunately, the more you see, the better things fall into place. <...>

Geomaterials are defined as ‘processed or unprocessed soils, rocks or minerals used in the construction of buildings or structures, including man-made construction materials manufactured from soils, rocks or minerals’ (Fookes, 1991). The definition deliberately includes manmade materials such as bricks or cement but excludes allied engineering materials whose manufacturing is more extensive, such as steel and synthetic paints.
