Book excerpt: The geology of the Blouberg mountain area, Northern Province, South Africa is characterised by a number of successor basins developed over a region which is underlain by a cratonic suture (the Palala Shear Zone). The suture was formed during the Limpopo Orogeny, due to oblique convergence of the Kaapvaal Craton and the Central Zone of the Limpopo Mobile Belt at either 2.65Ga or 2.0Ga. Post-collisional brittle reactivation along the Palala Shear Zone in the Blouberg study area is accommodated on the parallel Melinda Fault. The earliest basin developed in this area was that of the Blouberg Formation, which is preserved in an area restricted to the eastwards extension of the Palala Shear Zone. The Blouberg Formation can be divided into Lower and Upper Members. The widespread Lower Member is thought to have been deposited in a pull-apart basin, is characterised by braided fluvial sheetflood deposits, and is generally steeply-dipping or overturned, reflecting a subsequent southwards-vergent basin inversion. The Upper Member contrasts with the Lower Member in that it is preserved only rarely, is generally flat-:lying, and is composed of conglomerates with sub-angular cobbles of foliated basement rocks with rare granulestone beds, reflecting deposition in debris flows and braided rivers respectively. The tectonic event responsible for the southwards-vergent basin inversion of the Lower Member probably also uplifted proximal basement sources to the north and east, leading to deposition of the Upper Member in localised basins close to the southern strand of the Melinda Fault scarp. The syn-tectonic deposition of the Blouberg Formation was followed by a period of relative tectonic quiescence, and deposition of the Waterberg Group. The fluvial Setlaole Formation was succeeded by the predominantly aeolian Makgabeng Formation. Strata of these two formations are not preserved north of the Melinda Fault, probably due to the syn-Blouberg tectonic activity, which had led to development of high topography in this area. This palaeohigh gradually denuded throughout Waterberg sedimentation. Ultimately, the Mogalalcwena Formation, the youngest of the Waterberg units in the study area, onlapped northwards over these denuding highlands. After the end of Mogalakwena deposition, renewed tectonic activity led to approximately north-south orientated extension. Syn-Blouberg northwards-dipping reverse faults along the southern strand of the Melinda Fault were locally reactivated as normal faults, resulting in a half-graben type environment. A depository was created above the hanging wall, which filled with the strata of the Soutpansberg Group: initially volcanics of the Sibasa Formation erupted, followed by the clastic deposition of the Wyllies Poort Formation. Late-stage reactivation along the Palala Shear Zone is represented by the northern strand of the Melinda Fault, which is generally a dextral strike-slip fault, with up to 17km of total displacement.

Book excerpt: In this book the editors strive to cover all primary (i.e. non-applied) topics in Precambrian geology in a non-partisan way, by using a large team of international authors to present their datasets and highly divergent viewpoints. The chapters address: celestial origins of Earth and succeeding extraterrestrial impact events; generation of continental crust and the greenstone-granite debate; the interaction of mantle plumes and plate tectonics over Precambrian time; Precambrian volcanism, emphasising komatiite research; evolution and models for Earth's hydrosphere and atmosphere; evolution of life and its influence on Precambrian ocean chemistry and chemical sedimentation; sedimentation through Precambrian time; the application of sequence stratigraphy to the Precambrian rock record. Each topic is introduced and a non-partisan closing commentary provided at the end of each chapter. The final chapter blends the major geological events and rates at which important processes occurred into a synthesis, which postulates a number of "event clusters" in the Precambrian when significant changes occurred in many natural systems and geological environments.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers is a snapshot of modern hydrogeology in which highly technical methods and approaches sit side-by-side with overlapping legal, social, organisational, institutional and governance considerations. Groundwater is integral to many human and environmental systems. Indeed, there appears to be a growing realisation that some of the most pressing physical problems in the field of hydrogeology - over-abstraction, salinization or pollution - can only really be solved by taking a multi-disciplinary approach to the issues that takes all other related professions into account. Whilst a ‘technical’ solution may be readily deciphered, the larger challenge usually lies in the sustainably-funded and widely-accepted implementation of that measure. This book ranges from discussion and debate on the hot topic of hydraulic fracturing of wells or ‘fraccing’ for shale gas and its potential to disrupt groundwater systems, to the application of highly technical modelling procedures to help solve complex, real world problems. It is a window on the preoccupations of modern hydrogeologists and an insight into the way in which hydrogeological techniques and methods are being holistically adapted to address problems in the real world. This book is targeted at professional hydrogeologists, sociologists, experts in governance, law and policy as well as ecologists and other professionals that nowadays all sit alongside groundwater understanding. The book will also appeal to politicians, resource managers, regulators and others interested in sustainable water supply.
