From the first attempts to understand the origin of giant iron ore deposits, numerous false assumptions have been used as the basis of genesis models that have become standard and unquestioned, with later research generally seeking to find evidence supporting the existing models and ignoring contrary evidence. Many models were constructed based on extremely rare features, and their absence in the global abundance of iron formations was not considered important since there was no understanding of the major sedimentary structures, i.e. laminations and banding. Inconsistencies within the hypothetical models are either ignored or excused by proposing special circumstances, but no one considers that the models might be wrong or have only limited application. Many hypotheses regarding Earths history have been postulated from the difference between Phanerozoic and Precambrian iron-formations. In particular, the development of an oxygenated atmosphere has been deduced from the supposed evolution of iron-formations. The subject has provided a fertile field for research and models of Earths history, but without clear knowledge of the sedimentation, diagenesis and metamorphism of BIFs (branded iron formations), such models are speculative or even irrelevant. Since these models on the genesis and distribution of BIF were used as proxies to answer questions regarding the composition of the early oceans and atmosphere, weathering and transport conditions on early land surface, volcanism and continental development in the Archean eon, and as they affect exploration for the largest volume and most basic of industrial metals, they have an importance beyond academic sedimentary and stratigraphic interest. The aim of this book is to present a model for the origin of BIFs and derived high-grade iron ore deposits with global applications that are still subject to correction and change as new information becomes available and are free of illogical assumptions which do not conflict with either field observations or basic chemistry and physics.

This volume presents an exhaustive overview of major orebodies and mineral deposits of North Africa. It is intended both for academic researchers and especially for exploration geologists interested in mineral exploration in the northern part of the African continent. Recent changes in the mining laws of most countries in this region have encouraged international mining companies to invest in local mineral industries. Accordingly, this volume will be very useful for these professionals, as well as for researchers in the field of economic geology.

Sixty articles arranged in eight thematic sections refer to most recent geological and geophysical results of Antarctic research. The Precambrian of the East Antarctic shield and its geological history is considered as well as sub-ice topography, geophysics and stratigraphy, sedimentology and geophysics of the surrounding Southern Ocean. Particular emphasis is given to the connection of the Antarctic and the surrounding continents when forming part of Gondwana.

Earth as an Evolving Planetary System, Second Edition, explores key topics and questions relating to the evolution of the Earth's crust and mantle over the last four billion years. This updated edition features exciting new information on Earth and planetary evolution and examines how all subsystems in our planet—crust, mantle, core, atmosphere, oceans and life—have worked together and changed over time. It synthesizes data from the fields of oceanography, geophysics, planetology, and geochemistry to address Earth's evolution. This volume consists of 10 chapters, including two new ones that deal with the Supercontinent Cycle and on Great Events in Earth history. There are also new and updated sections on Earth's thermal history, planetary volcanism, planetary crusts, the onset of plate tectonics, changing composition of the oceans and atmosphere, and paleoclimatic regimes. In addition, the book now includes new tomographic data tracking plume tails into the deep mantle. This book is intended for advanced undergraduate and graduate students in Earth, Atmospheric, and Planetary Sciences, with a basic knowledge of geology, biology, chemistry, and physics. It also may serve as a reference tool for structural geologists and professionals in related disciplines who want to look at the Earth in a broader perspective. - Kent Condie's corresponding interactive CD, Plate Tectonics and How the Earth Works, can be purchased from Tasa Graphic Arts here: http://www.tasagraphicarts.com/progptearth.html - Two new chapters on the Supercontinent Cycle and on Great Events in Earth history - New and updated sections on Earth's thermal history, planetary volcanism, planetary crusts, the onset of plate tectonics, changing composition of the oceans and atmosphere, and paleoclimatic regimes - Also new in this Second Edition: the lower mantle and the role of the post-perovskite transition, the role of water in the mantle, new tomographic data tracking plume tails into the deep mantle, Euxinia in Proterozoic oceans, The Hadean, A crustal age gap at 2.4-2.2 Ga, and continental growth

Iron Ore: Mineralogy, Processing and Environmental Sustainability, Second Edition covers all aspects surrounding the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of the global infrastructure. The book explores new ore types and the development of more efficient processes/technologies to minimize environmental footprints. This new edition includes all new case studies and technologies, along with new chapters on the chemical analysis of iron ore, thermal and dry beneficiation of iron ore, and discussions of alternative iron making technologies. In addition, information on recycling solid wastes and P-bearing slag generated in steel mills, sustainable mining, and low emission iron making technologies from regional perspectives, particularly Europe and Japan, are included. This work will be a valuable resource for anyone involved in the iron ore industry. - Provides an overall view of the entire value chain, from iron ore to metal - Includes specific information on process/stage/operation in the value chain - Discusses challenges and developments, along with future trends in the iron ore and steel industries - Incorporates new, sustainable mining techniques
