The second edition of this unique pocket field guide has been thoroughly revised and updated to include the advances in physical volcanology, emplacement of magmas and interpreting structures and textures in igneous rocks. New techniques include AMS and geophysical studies of pluton shape at depth. New topics introduced include the occurrence of porphyrys, laccoliths and magma sediment interaction, and new sections feature Granitic rocks, basaltic rocks, magma mixing and mingling, and engineering properties and mineralization.
The book begins with an introduction focusing on the importance of fieldwork and geological interpretation with chapter two dealing with field techniques. The following chapters focus on the description of outcrops, individual specimens and their interpretation and mode of occurrence. The remaining chapters go into great detail on volcanic and plutonic rocks, touching on the subject of metamorphism in addition. This book is part of the successful Field Guide series, and retains its handy pocket size for use in the field.
