The origin of granite has for long fascinated geologists though serious debate on the topic may be said to date from a famous meeting of the Geological Society of France in 1847. My own introduction to the subject began exactly one hundred years later when, in an interview with Profes sor H. H. Read, I entered his study as an amateur fossil collector and left it as a committed granite petrologist - after just ten minutes! I can hardly aspire to convert my reader in so dramatic a way, yet this book is an attempt, however inadequate, to pass on the enthusiasm that I inherited, and which has been reinforced by innumerable discussions on the outcrop with granitologists of many nationalities and of many shades of opinion. Since the 1960s, interest in granites has been greatly stimulated by the thesis that granites image their source rocks in the inaccessible deep crust, and that their diversity is the result of varying global tectonic context. So great a body of new data and new ideas has accumulated that my attempt to review the whole field of granite studies must carry with it a possible charge of arrogance, especially as I have adopted the teaching device of presenting the material from a personal point of view with its thinly disguised prejudices.

Outcrops of granitic rocks cover a large proportion of the Earth's surface and host a range of spectacular landforms and landscapes, from extensive plains dotted by inselbergs to deeply dissected mountain ranges. They are often strikingly beautiful, but more importantly, they provide valuable insights into the mechanisms of geomorphic evolution both in the past and at present. The book offers a comprehensive view of the geomorphology of granite areas, examining individual landforms and their assemblages. Weathering processes, and the phenomenon of deep weathering in particular, are given much emphasis as these are fundamental to the understanding of the geomorphic evolution of granite areas. Granite landforms directly related to weathering, such as boulders, tors, inselbergs, and features of surface microrelief are examined in respect to their characteristics and origin. Patterns of slope evolution are shown in the context of both rock slopes and deeply weathered terrains. Granite geomorphology in the coastal, periglacial and glacial context is presented to show how the characteristics of granite control landform evolution in these specific environments. In the closing part a variety of geological controls is reviewed and their primacy over other factors is advocated, followed by an attempt to provide a typology of natural granite landscapes. Finally, certain specific ways of human transformation of granite landscapes are presented. The book will be useful to a range of earth science disciplines, including geomorphology, igneous petrology, engineering geology and soil science. Cultural geographers and people dealing with conservation of geological heritage should find it of interest. Examples from all parts of the world and extensive referencing ensure that it will act as an up-to-date guidebook to the fascinating world of granite geomorphology.
