As a result of its bouyancy, continental crust is rarely subducted meaning that successive episodes of continental deformation imparts a complex geological character that is not found in younger oceanic lithosphere.

Continental Reactivation and Reworking

This volume is a state of the art look at our understanding of joint development in the crust. Answers are provided for such questions as the mechanisms by which joints are initiated, the factors controlling the path they follow during the propagation process, and the processes responsible for the arrest of joints. Many of the answers to these questions can be inferred from the geometry of joint surface morphology and joint patterns. Joints are a record of the orientation of stress at the time of propagation and as such they are also useful records of ancient stress fields, regional and local. Because outcrop and subsurface views of joints are limited, statistical techniques are required to characterize joints and joint sets. Finally, joints are subject to post-propagation stresses that further localize deformation and are the focus for the development of new structures.

The Initiation, Propagation, and Arrest of Joints and Other Fractures

Non-continental margins lack thick lavas that are generated as continental crust thins immediately prior to the onset of seafloor spreading. They may form up to 30 per cent of passive margins around the world. This volume contains papers examining an active margin, fossil margins that border present day oceans, and remnants of margins exposed today in the Alps. The papers present evidence across a range of scales, from individual mineral grains, through borelide cores and outcrop, to whole margins at the crustal scale.

A Comparison of Evidence from Land and Sea

Non-volcanic Rifting of Continental Margins

The sustainable development of minerals, which are non-renewable resources, is a major challenge in today's world. In this regard the true definition of 'sustainability' is a debating point in itself: can such a concept exist with respect to non-renewable resources? Perhaps the ideal sustainability model is one that minimizes negative environmental impact and maximizes benefits to society, the economy and regional/national development. Developed and near-developed economies rely for commodity supplies on developing countries where major mining operations are often a mainstay of the domestic economy. Limited environmental regulation and low wages lead to charges of exploitation. Also, large numbers of people have no alternative to living by informal, often dangerous, 'artisanal' mining. This Special Publication gives examples from developing countries from all scales of mineral extraction. The volume reviews environmental, economic, health and social problems and highlights the need to solve these before sustainability can be achieved. The better solutions require mutual understanding, through full involvement of all stakeholders, education, training and investment so that small-scale and artisanal mines can grow into well-managed operations. At larger scales, most major international mining companies have now improved their practices and are monitoring their progress, although there is no room for complacency in this rapidly changing area.

The influence of Bill Bishop is reflected throughout this volume, even though his sudden death stopped a brilliant research career in full flow. Most of the authors are connected with Bill as research collaborators and students, or as the next generation of students of these supervisors. The volume begins with an appreciation of Bill's life and work; the research contributions that then follow are arranged in three thematic sections, each with a scene-setting editorial overview: Part 1. Early Miocene of Uganda, including the first full account and discussion of the recently discovered oldest known hominoid Morotopithecus bishopi. Part 2. Middle Miocene to Pleistocene of the Tugen Hills, Kenya, a comprehensive account of the hominids and their environmental context from members of the Baringo Basin Project. Part 3. Quaternary Environments, with particular emphases on the English Midlands, western Scotland and southern Africa. Throughout this commemorative volume, the determination of editors and authors to place the results of specialist research into their environmental context is perhaps the clearest indication of the visionary influence of Bill Bishop.
