Geology is a field science. Without sustained fieldwork, no theoretical aspect of geology can be taught and no geological and mineral exploration or research can be carried out. In short, without field studies there would be no science of geology.Practical field training of students is therefore an essential requirement of undergraduate and postgraduate courses in geology. Students have to learn to make independent geological observations and measurements on the ground. Education in fieldwork, like any other course, also requires good course materials. This book is an attempt to provide a suitable text on field geology suited to Indian conditions.Written by an eminent field geologist, the book covers all aspects of field geology-right from preparation for the trip and correct handling of instruments and other equipment, to mapping and observation of various geological features and collection of materials for further study in the laboratory. Interspersed throughout the text are practical hints for the successful conduct of the assigned work in different terrains.This guide should be carried to the field for regular consultation. The text with its straightforward presentation reflecting the experience of a half-century of the author as a field geologist should prove to be a boon to the students of geology.
