This book is about metamorphic rocks: the processes involved in
their formation and the reasons why they occur at particular places
on the continents. It has been written to serve as an elementary
text on the subjects of metamorphism and mountain building for
non-specialist stu dents of geology. It will be equally useful
where geology is either the main or subsidiary subject and could be
used by students intending to advance further in geology (the list
of advanced texts in the further reading section would be more
appropriate to such students). My inten tion in writing this book
has been to try to dispel the notion that metamorphism comprises
the 'haunted wing' of geology. Admittedly, there are rather a large
number of technical terms in the book, but I hope that after
working through it you will not find metamorphism an unduly
difficult or obscure aspect of geology. Throughout, I have
emphasised the strong links between mountain building, plate
tectonics and metamorphic processes. The book introduces
metamorphic rocks by considering their textures and field
relations, then moves on to deal with the factors controlling
metamorphism. Case studies of areas of metamorphic rocks are then
presented in the context of modern theories of the Earth's
activity, and the place of metamorphic rocks in the formation of
ancient and young mountain belts is analysed. New technical terms
and concepts are explained in context as they are introduced,
important terms being emphasised in bold print."
This guide is for those who wish to understand the interplay
between rocks and scenery in a truly classic geology in Europe.
Nowhere else in Britain is this link to be more clearly observed.
Key geological localities that make the Scottish Highlands a unique
region for the study of geology are linked together geographically
in a series of journeys. The Western Highlands contain some of the
oldest rocks in Europe in a landscape formed more than a billion
years ago that has re-emerged from the depths. Geologists have been
examining these rocks since the early nineteenth century and, in
spite of intense research in this tiny fraction of the Earth's
surface, major controversies still surround some of the rock
formations. Many fundamentally important concepts in geology were
first developed here and then applied elsewhere around the world.
The region is an outstanding natural laboratory for the study of
mountain building and folding, including the discovery that thick
sequences of rocks have been turned completely upside down, and
pushed sideways for over 100 kilometres. Representatives of all the
major rocks types are found here, and their ages span
three-quarters of geological time since the Earth began, some four
and a half billion years ago. The journeys and localities are
detailed in chapters: Tongue to Lochinver; Lochinver, Assynt,
Ullapool; Ullapool to Gairloch; Gairloch to Kyle of Lochalsh; Kyle
of Lochalsh, Glenelg, Mallaig, Cluanie, Glen Roy; Fort William,
Loch Eil, Glenfinnan, Lochailort, Ardnamurchan, Strontian; Fort
William, Ballachulish, Kentallen, Oban, Easdale, Kilmartin,
Tayvallich and Kilmory; Fort William, Ben Nevis and Glen Nevis,
Ballachulish, Glencoe, Glen Etive, Glen Orchy and Loch Lomond.
Excursions are easily accessible, along footpaths and the coast,
with a few more challenging options, including Ben Nevis,
Scotland's highest mountain. This is an ideal accompaniment for
geologists and earth science students visiting the Western
Highlands.
The six hundred miles between the northernmost Shetland island and
the Mull of Galloway in the South of Scotland contain some of the
most interesting geology and most varied landscapes in Europe. This
variety was the inspiration for a tradition of geological
investigation that stretches back to the earliest earth scientists.
The origins of the Scotland that we know today lie in five quite
distinct geological histories. The Geology and landscapes of
Scotland takes the reader on a tour of each of these regions in
turn, starting with the Northwest Highlands and Outer Hebrides,
which contain some of the oldest rocks on Earth, through the
mountain terrains of the Highlands and Uplands to the Lowlands and
then the fringes of the North Sea. A section describes the volcanic
provinces of Scotland; another deals with the effects of the Ice
Ages while a final section looks at Scotland's natural resources.
Of equal appeal to the professional geologist seeking a broad
overview of a much-studied terrain and a resource for the resident,
visitor, walker, climber or angler who wants to understand the
origins of the landforms they observe, Geology and landscapes of
Scotland has proved itself as a reliable guide. In this thoroughly
revised edition the many illustrations are presented in colour.
