Southern Africa is home to many important and interesting minerals, as well as a wide array of beautiful gemstones – including diamonds from South Africa, emeralds from Zimbabwe and tourmalines from Namibia. Minerals & Gemstones of Southern Africa is not only the most up-to-date publication on the minerals of Botswana, Eswatini, Lesotho, Namibia, South Africa, southern Mozambique and Zimbabwe, but also the first to feature the region’s gemstones. Mineral species descriptions detail their gemological properties, history, occurrence and uses, and are illustrated with striking full-colour photographs. The book includes: An introduction to the geology of the region. Detailed descriptions of minerals, including their gemological properties, history, occurrence and uses. Multiple full-colour photographs of the species. An invaluable guide for collectors, gemologists, students and anyone with an interest in earth sciences. Sales points: An important record of the region’s diverse mineral and gemstone heritage. Over 1 000 full-colour photographs. Concise, authoritative text.

Fractal geometry allows the description of natural patterns and the establishment and testing of models of pattern formation. In particular, it is a tool for geoscientists. The aim of this volume is to give an overview of the applications of fractal geometry and the theory of dynamic systems in the geosciences. The state of the art is presented and the reader obtains an impression of the variety of fields for which fractal geometry is a useful tool and of the different methods of fractal geometry which can be applied. In addition to specific information about new applications of fractal geometry in structural geology, physics of the solid earth, and mineralogy, proposals and ideas about how fractal geometry can be applied in the reader's field of studies will be put forward.
