This manual provides guidelines and instructions for performing and documenting field work. The manual is a ready reference for anyone engaged in field-oriented engineering geology or geotechnical engineering. The manual is written for general engineering geology use as well as to meet Reclamation needs. The application of geology to solving engineering problems is emphasized, rather than academic or other aspects of geology <...>

While ancient man must have had some intuitive knowledge of geology, as evidenced by the feats of mining and civil engineering performed in the distant past, the present science of geology owes much of its origin to the civil engineers working in the eighteenth century. These engineers, while constructing the major engineering works associated with the industrial revolution, had the opportunity to view and explore excavations in rocks and soils. Some, intrigued by what they saw, began to speculate on the origin and nature of rocks, and the relationships between similar rocks found in different places. Their ideas and theories, based on the practical application of their subject, formed the groundwork for the development of geology as a science. Engineers such as Lewis Evans (1700–1756) in America, William Smith (1769–1839) in England, Pierre Cordier (1777–1862) in France and many others were the ‘fathers’ of Geology. <...>

With the title Engineering Rock Mechanics, what is this book about? It is about the discipline, based on mechanics, which is used to design structures built on or in rock masses. These structures, which encompass building foundations, dams, rock slopes, tunnel, caverns, hydroelectric schemes, mines, etc., depend critically on the rock mass properties and the interaction between the rock mass and the engineered structure. As a result, the distinct discipline of engineering rock mechanics has developed. The term ’rock mechanics’ refers to the basic science of mechanics applied to rocks; whilst the term ’rock engineering’ refers to any engineering activity involving rocks. Thus, the term ’engineering rock mechanics’ refers to the use of rock mechanics in rock engineering-within the context of civil, mining and petroleum enpeering. Because rock mechanics can also be used to study structural geology, we emphasize through the title that it is the rock mechanics principles in the engineering context that we are presenting <...>

Environmental chemistry, Seventh Edition, continues much the same organizational structure, level, and emphasis that have been developed through preceding editions. In addition to providing updated material in the rapidly developing area of environmental chemistry, this edition emphasizes several major concepts that are proving essential to the practice of environmental chemistry at the beginning of the new millennium.
