The Earth sciences are a collection of disciplines that consider Earth’s atmosphere and hydrosphere, as well as the planet’s solid aspect, the geosphere. The academic disciplines concerned with the geosphere are collectively called the geological sciences, or geosciences. Each one considers different facets of Earth’s surface and interior, such as its rocks, minerals, and their chemistry, the evolution and role of its landforms, and its geologic history. Although most of the geosciences exist to develop a greater understanding of the parts and processes involved in the solid Earth, the subfield of economic geology takes as its mission the extraction of rocks and minerals and their conversion to useful products.<...>

The great classical tectcnicians, such as Suess, Argand and Wegener, att empted (0 und erstand. without the benefi t of the plate tecto nic theory. the workings of the Ea rth engine as a who le, and the part that deformation played in that who le. In my student days, I deri ved great pleasure and benefit from De Sitter's textbook on str uctural geology where the study of geo logical structures and major Earth structure received more or less equal rreatment. Since then, until relatively recently, there has been a tendency for str uctu ral geology to become more parochial and inward-looking, despite the enormous advances in understand ing that the plate tectonic revolutio n has brought abo ut. I have longfelt the need, therefo re, for a bo ok tha t would give students a tectonic overview in which geo logical structures and deformation could be seen in their context as byproducts of the plate tectonic system <...>

This book aims to give the first comprehensive explanation of the metallogenic areas of Fennoscandia, which have recently been described in the Metallogenic Map of the Fennoscandian Shield. The Fennoscandian metallogenic map shows the extent of presently known metallogenic areas.
