Book Description
The book deals with the record of important Neoproterozoic to Early Palaeozoic events in southwestern Gondwana, that heralded the Cambrian explosion and the dawn of modern ecosystems. It contains a detailed account of the Neoproterozoic to Cambrian geological record in a poorly-known part of the world, which is at the same time key to understand fundamental processes at the Proterozoic-Cambrian transition. The emphasis is placed on litho-, bio-, chemostratigraphy and magmatism. The palaeoclimatic, tectonic, evolutionary radiation and extinction events and associated mineralizations will be identified and discussed. A synthesis of all data is provided at the end of the book, integrating the data from all cratons and fold belts in southwestern Gondwana. The events will be individualized, their impact discussed and correlations between different successions both within and outside Gondwana proposed.The book is organized in three sections. Section one is an introduction to the neoproterozoic and Cambrian seen as a time of upheavals, extremes and innovations. Section two comprises nineteen chapters dealing with the neoproterozoic-Cambrian events in southwestern Gondwana. Section three will provide a synthesis on every major topic, and a critical assessment of the global implications of the presented data.

Book Description
Die vorliegende Studie ist Ergebnis einer in Namibia und Deutschland durchgeführten Literaturrecherche zu sedimentgebundenen Blei-Zink- (Kupfer-Barium)-Vorkommen in den Pan-Afrikanischen Kaoko- und Gariep- Faltengürteln der nördlichen und südlichen Küstenregion Namibias. Die Literaturstudie zeigt, dass metallogenetische Untersuchungen der Buntmetallmineralisationen in diesen orogenen Gürteln Namibias einen aktuellen Forschungsschwerpunkt darstellen. Begründet liegt dies unter anderem in den vergleichsweise begrenzten, derzeit bekannten Rohstoffvorräten an Zink, Blei,Baryt, Silber und Kupfer, die zukünftig einen erhöhten Innovationsbedarf haben und somit verstärkte Explorationsanstrengungen erfordern. Dies wird auch deutlich durch die defizitäre Bilanz aus Zinkproduktion und -nachfrage von 1994 bis 1999 der westlichen Welt. Insbesondere seit den neunziger Jahren wurden in Namibia verstärkt Explorationsinvestitionen durch internationale Explorations- und Bergbaufirmen getätigt. Das Land verfügt über eine lange und erfolgreiche Bergbautradition, deren Wurzeln in einer relativ stabilen politischen Situation, exzellenter Infrastruktur, einem modernen Bergrecht und hochwertigen, gut zugänglichen geologischen und geophysikalischen Daten begründet liegen. - Schlieilich bietet sich die Anwendung der Ga/Ge-Geothermometrie von Sphalerit an und diese sollte in verschiedenen Erzparagenesen der Rosh Pinah Lagerstätte getestet werden. Hierbei verspricht ein kritischer Vergleich der geochemisch ermittelten TGa/Ge mit der mikrothermometrisch bestimmten TF.I. und vor allem der Gebrauch des Verhältnisses TGa/Ge / TF.I. als Proximitätsindikator auch einen positiven Beitrag zur metallogenetischen Grundlagenforschung.

Book Description
This volume focuses on Late Mesoproterozoic to early Cambrian events related to Gondwana assembly and break up. The nineteen papers provide a comprehensive review including advanced knowledge and new data from all critical areas of East Gondwana. The recent knowledge of the evolution of East Gondwana, which was regarded as an integral part of the Mesoproterozoic supercontinent Rodinia, is the major theme of the volume, which is reinforced by highlighting this radical and new understanding of the evolution of this region.
