A Practical Manual on Geologic Field Mapping

The book ‘A Practical Manual to Geologic Field Mapping’ organises and presents, in a logical manner, important information essential for study of rocks in their natural setting. The book is divided into five short chapters. Chapter one introduces students to the subject of geological mapping, its objectives and fundamental concepts. The second chapter deals with pre-field preparation and planning. It reviews the safety and risk assessment as well as relevant equipment and supplies necessary for a successful field mapping. Chapter three deals with the actual field mapping exercise explaining with illustrations, the various approaches adopted in mapping the three basic types of rocks (igneous, sedimentary and metamorphic). It also includes how some geological structures such as faults and folds can be detected in the field. Chapter four describes how structures are measured and recorded in the field. It includes illustrations of how the data are plotted (analysed) and how samples are collected and coded. The last chapter (Chapter five) describes the process of constructing the final geological map and explains the general format for report writing.
