The Swaziland Supergroup in the Barberton Greenstone Belt (BGB) consists of a lower, predominantly volcanic sequence, the Onverwacht Group; a middle volcaniclastic and quartz-poor clastic succession, the Fig Tree Group; and an upper quartzose terrigenous unit, the Moodies Group.

This lively introduction to geologic fracture mechanics provides a consistent treatment of all common types of geologic structural discontinuities. It explores the formation, growth, and interpretation of fractures and deformation bands, from theoretical, field, and laboratory-based perspectives, bridging the gap between a general textbook treatment and the more advanced research literature. It allows the reader to acquire basic tools to interpret discontinuity origins, geometries, patterns, and implications using many of the leading and contemporary concepts known to specialists in the field. Exercises are provided at the end of each chapter, and worked examples are included within each chapter to illustrate topics and enable self-study. With all common geologic structures including joints, hydrofractures, faults, stylolites, and deformation bands being discussed from a fresh perspective, it will be a useful reference for advanced students, researchers, and industry practitioners interested in structural geology, neotectonics, rock mechanics, planetary geology, and reservoir geomechanics. <...>

Geologic hazards represent substantial danger to humans and their works. The hazards may exist as a consequence of natural events, but often they are the result of human activities. Slope failures, such as landslides and avalanches, can occur in almost any hilly or mountainous terrain, or offshore, often with a very frequent incidence of occurrence, and can be very destructive, at times catastrophic.

Geologic maps are among the basic tools used by anyone who wants to gain an understanding of the surface and shallow subsurface of the earth. They provide information about the types of materials that are present and the configuration of those materials in three dimensions.
