R 280Jy spaar R 70
Southern Africa boasts many spectacular examples of rocks and minerals; volcanic lavas make up the dramatic Drakensberg mountain range, granite mountains form stunning scenery in Namibia and Zimbabwe, and some of the most ancient rocks on Earth - over 3 000 million years old - are to be found on the subcontinent. The region is home to many important and interesting minerals, as well as a wide array of beautiful gemstones - diamonds from South Africa, emeralds from Zimbabwe and tourmalines from Namibia.

Field Guide to Rocks and Minerals of Southern Africa is the first definitive field guide to document the common, rare and unusual rocks and minerals of South Africa, Namibia, Botswana, Zimbabwe, Lesotho, Swaziland and southern Mozambique. Supported by more than 500 full-colour photographs, the text describes in detail a wide range of the region's common and attractive rocks and minerals. Authoritative information is presented in a user-friendly manner and is enlivened by box and panel features.

Meer as 'n metafoor

R 299
Moderne wetenskap bevestig vandag wat filosowe vir eeue reeds verkondig, naamlik dat die wêreld 'daar buite' en die beelde wat ons in ons koppe daarvan ronddra, totaal verskillende werklikhede is. Hoe hulle verskil, is die reis waarop Maryna Blomerus haar lesers in Meer as 'n Metafoor wil neem.
Meer as 'n Metafoor ontsluit die diepte en krag van 'n heelal wat volgens die beginsels van selfverwysing en holisme, soos uitgelê deur Jan Smuts in Holism and Evolution, in beheer is van sy eie ewolusie, en redeneer dat die mens die kollektiewe oog is waarmee hierdie heelal homself ken, waarneem en voortdurend herskep.

R 290
R 232Jy spaar R 58
Africa is home to more than the Cradle of Humankind. It was the core of the ancient supercontinent Pangaea, and comprises some of the oldest and most extraordinary geology on planet Earth.

This detailed and colourful book features 44 of the continent's most spectacular and interesting 'geosites', from Table Mountain in the south to the eroded necks and plugs of the Hoggar region in Algeria; and from the volcanic islands of the Atlantic Ocean to the continental fragments off the African east coast. Each site is authored by a geologist (or specialist in a related field) with in-depth knowledge about the particular feature or landform: how it formed and developed, its current geological status, ecological impact, and its archaeological and cultural interest.

Supported with many photographs, maps, satellite images and explanatory illustrations, the text is accessible to geologists and lay enthusiasts alike, unpacking the hows and whys of Africa's most intriguing landforms, sites and geological features.

Understanding Minerals & Crystals

R 320
R 256Jy spaar R 64
Minerals are the building blocks of rocks - they make up the solid Earth's crust. Understanding Minerals & Crystals takes a close look at minerals, how they form, why they differ and how to go about identifying them. It begins by examining the nature of atoms and the way they bind together to form minerals with distinctive crystal structures; and it discusses the nature and classification of these crystals, and includes a mineral identification key. The second part of the book contains detailed descriptions of some 80 common and important minerals, including how they were named, their properties, ID pointers, uses and where in the world they are found. All are lavishly illustrated with full-colour photographs. This book will be invaluable to those interested in any of the earth sciences, or in mineral/crystal collecting - from academics and students to general enthusiasts.

We all know South Africa has problems; we read about them in the newspapers, we see them on the streets and many people experience them in their daily lives. Fortunately, many of these problems can be solved using innovation and science. Innovation takes a look at inventions - developed in South Africa by South Africans - to address issues in the areas of healthcare, energy, environment and industry. Some of these inventions, such as a tea bag created to filter water for communities in rural areas, can save lives; others, such as a unique way to beneficiate titanium, could spell a new era of industry in the country.
The book is broken down into sections on environment, health, energy, industry and education, and in each of those parts are examples of South African innovations, from a satellite system to map fires to the concept of sterilising mosquitoes to stop the spread of malaria.

These have been developed by numerous organisations and institutions and showcase South Africa's excellence.

The Magaliesberg: Biosphere Edition

R 350
R 280Jy spaar R 70
The Magaliesberg by Vincent Carruthers was first published in 1990. A second edition was published in 2000 and reprinted in 2007. It has now been revised again for publication to coincide with the international proclamation of the Magaliesberg Biosphere. The book has been highly successful and is a valuable source of information about the Magaliesberg, its geology, biodiversity and human history. During the decades since its publication substantial changes have taken place in in South Africa and in the Magaliesberg region and the revised editions to the book have taken cognisance of these. Most importantly, The Magaliesberg has had a profound influence on government and public awareness of the region and it has led directly to application to UNESCO for the Magaliesberg to be registered as a Biosphere Reserve in June 2014. This international recognition of the importance of the area will greatly enhance conservation efforts and stimulate tourism, education and research in the region. The current edition of the book celebrates this accomplishment and it will continue to be the primary source of information for public readership.

The Magaliesberg mountains are more than two billion years old - one of the oldest mountain ranges on the planet - and the book traces their creation and the changes in the landscape over this vast passage of time. The ancient geomorphology has given rise to a wide spectrum of different habitats and a consequent diversity of plant and animal life. The book's extensive descriptions of the fauna and flora of the area inspire the reader to consider the impact that man has on his environment. Each of the main plant and animal groups - trees, flowers, birds, mammals, reptiles and insects - has a full chapter devoted to it with checklists of every species found in the area indicating both the Scientific as well as common names.

The second half of the book is dedicated to the immensely rich human history of the Magaliesberg and is equally comprehensive. Starting with the pre-hominid ancestors of humankind it describes the paleontological and archaeological evidence of the succession of people who have lived in the mountains over hundreds of thousands of years. Stone Age tools and etchings, Iron Age walled villages as well as the forts and battlefields of more recent centuries are all brought to life in detailed accounts of the people and events of the time.

R 236Jy spaar R 59
The prehistoric record of southern Africa extends back some 2 million years. The oldest cultural artefacts are stone tools such as handaxes, cleavers and choppers. In more recent centuries, archaeologists have found an extensive repertoire of artefacts including not only stone tools, but tools of bone, wood and shell as well as beads, jewellery, grinding stones, clothing, fishing equipment, burials and southern Africa's enigmatic rock art. Understanding these painted scenes and menageries is not immediately obvious. Using this interpretive guide, visitors to these ancient shrines can properly interpret rock art panels and make sense of the complex world of Bushman beliefs.

How does rock get folded? etc. For each question there are explanations, be they geological, mineralogical, astronomic - whatever the field, the evidence is carefully presented and explained so that even those with little knowledge in these fields can understand the processes that have been at work. The book is vividly illustrated and supported with full colour photographs.
