El concepto de espacios marítimos, su extensión y límites, así como las actividades de los Estados, las personas y las comunidades costeras, entre otros temas, son hechos tan antiguos como la humanidad misma. Durante el siglo pasado el derecho del mar experimentó un cambio notable en cuanto a la expansión del Estado hacia la alta mar, el establecimiento de un régimen para los fondos marinos y el cambio cualitativo de los derechos y regímenes aplicables en los océanos.

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. <...>
