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.

Ore deposits form by a variety of natural processes that concentrate elements into a volume that can be economically mined. Their type, character and abundance reflect the environment in which they formed and thus they preserve key evidence for the evolution of magmatic and tectonic processes, the state of the atmosphere and hydrosphere, and the evolution of life over geological time. This volume presents 13 papers on topical subjects in ore deposit research viewed in the context of Earth evolution. These diverse, yet interlinked, papers cover topics including: controls on the temporal and spatial distribution of ore deposits; the sources of fluid, gold and other components of orogenic gold deposits; the degree of oxygenation in the Neoproterozoic ocean; bacterial immobilization of gold in the semi-arid near-surface environment; and mineral resources for the future, including issues of resource estimation, sustainability of supply and the criticality of certain elements to society.
