Folding and fracturing of rocks / Складчатость и трещиноватость горных пород

Through geological time the earth's crust has suffered a sequence of spasmodic deformations. Since this phenomenon is now well established, structural investigations have entered a second phase concerned with a rigorous analysis of the form and formation of the structures and with the nature and origii:i of the forces which led to the deformation. This book outlines the basic theories of stress, strain, and the properties of rock materials, and considers some of their implications in geological processes. <...>
