Orogenic-Type Polymetallic Mineralization Associated with Multistage Orogenesis in Northern North China Plate by Wenbo Li,Richen Zhong,Yanjing Chen,Qiaohui Pi Pdf

This book focuses on the geological characteristics and genesis of several base metal deposits in the northern margin of the North China Plate, namely the Bainaimiao Cu-Au-Mo, the Huogeqi Cu-Pb-Zn, the Dongshengmiao Zn-Pb-Cu and the Jiashengpan Zn-Pb deposits. These deposits have geological and geochemical affinities with orogenic-type deposits, such as shear zone-controlled mineralization and carbon-rich low-salinitiy ore-forming fluids, and are characterized by multistage ore-forming histories. Remobilization of the pre-enriched (stratabound or porphyry-type) base metals took place as responses to orogenesis and metamorphism, leading to metal redistribution and the formation of orogenic-type orebodies. The formation of orogenic-type base metal deposits is enigmatic, and the case studies presented in this book provide insights into understanding the genesis of this type of deposits. In particular, pre-enrichment of base metals seems to be important, in terms of preconditioning for later shear zone-controlled mineralization, since base metals are believed to have limited solubilities in the low-salinity ore-fluids.

Metallogenic Theory and Exploration Technology of Multi-Arc-Basin-Terrane Collision Orogeny in “Sanjiang” Region, Southwest China by Wenchang Li,Guitang Pan,Zengqian Hou,Xuanxue Mo,Liquan Wang,Xiangfei Zhang Pdf

This open access book presents a new structural model of “multi-arc-basin-terrane system” based on the in-depth research of the Nujiang-Lancangjiang-Jinshajiang region, especially several Paleo-Tethys ophiolitic mélange belts and sets of arc-basin systems, and a new orogenic model of “The Hengduan shan Mountains” based on penetrated research on spatial-temporal framework and orogenic models of different orogenic belts under large-scale strike-slip-shear-nappe structures evolution. The authors paid special attention on the coupling relation between orogeny and metallogenesis. The metallogenesis and dynamic process are probed under the crust–mantle interaction and material-energy exchange-transmission background and the tectonic units evolution. The ore genesis and distribution of deposits have been thoroughly analyzed, and the metallogenic theories of "multi-arc-basin-terrane" and "intracontinental tectonic transformation" in the Nujiang-Lancangjiang-Jinshajiang region have been carried out. This book also illustrates how to explore metallic deposits in the Nujiang-Lancangjiang-Jinshajiang region by using the metallogenic regulations. Meanwhile, this book has high reference value for researchers working in the fields of basic geology, environmental geology, and energy geology.

Zhang Peili by Orianna Cacchione,Pi Li,Katherine Grube,Robyn Farrell Pdf

Considered the first Chinese artist to work in video, Zhang Peili (b. 1957) manipulates perspective, close-ups, and framing to create astonishing recordings of banal repeated actions, such as breaking glass, reading, washing, shaving, and blowing bubble gum. He is a pioneering figure, experimenting with a video camera in the late 1980s, exploring digital formats in the early 2000s, and developing large-scale, immersive scenes today. Despite Zhang's pivotal role in the global history of video art, his oeuvre has received relatively little attention. This book, which includes insightful essays, color plates, and an illustrated chronology, is one of the few in-depth explorations in English of this important artist's work.

Gold Metallogeny and Exploration by B. Foster Pdf

Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses of all major aspects of gold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.

The Role of Halogens in Terrestrial and Extraterrestrial Geochemical Processes by Daniel E. Harlov,Leonid Aranovich Pdf

The book summarizes the knowledge and experiences concerning the role of halogens during various geochemical processes, such as diagenesis, ore-formation, magma evolution, metasomatism, mineralization, and metamorphism in the crust and mantle of the Earth. It comprises the role of halogens in other terrestrial worlds like volatile-rich asteroids, Mars, and the ice moons of Jupiter and Saturn. Review chapters outline and expand upon the basis of our current understanding regarding how halogens contribute to the geochemical/geophysical evolution and stability of terrestrial worlds overall.

Mineralization and Sustainable Development in the West African Craton by T. Aïfa Pdf

This Special Publication combines results obtained by interdisciplinary groups from numerous academic institutions working on Paleoproterozoic formations to decipher the origins of the main mineralization resources in the West African Craton (WAC) and their impacts on African economic development. Structural, geophysical, sedimentological, stratigraphical, geochemical, petrophysical and mineralogical analyses have been used to highlight the complexities involved in mineralization emplacement and its origin and evolution within the WAC. Fourteen articles contribute to new knowledge in mineral research. They show that the geodynamic evolution of the WAC is complex from one area to another: it involves subduction, collision and obduction during several deformation phases ranging from Birimian (2.3–2.0 Ga) to Pan-African (650–450 Ma) events. Various modelling techniques, when integrated, help in understanding the mechanisms of mineralization emplacement, some of which are still a matter of debate. The challenge for further studies is mitigation for sustainable development that can be appropriately used to minimize such damage.

Structural Control of Mineral Deposits by Alain Chauvet Pdf

"Structural Control” remains a crucial point that frequently lacks in any scientific and/or economic analysis of ore deposits, whatever their type and class. The case of lode deposits is exemplary, although also other deposits, like breccia pipe, stockwerk, massive sulphides, skarn, etc., can, surprisingly, be concerned. Several concepts like the gold-bearing shear zone have not proven valid during the last few decades in terms of our understanding of gold deposit and have been totally abandoned. Additionally, the relationships between magmatism, regional tectonic context, and mineralization remain uncertain and have been debated in several recent publications. This demonstrates that this issue is still relevant, and its solution may help in the distinction between intrusion-related and orogenic deposits. In this Special Issue, we particularly invite any case study of mineral deposits, in which it has been demonstrated that structural geology may have a significant role in the establishment of the deposit model of formation and/or on exploration and exploitation programs. Examples in which the structural model diverges from those described in the classical literature are particularly welcomed, including studies in which relationships with magmatism can be suspected and/or demonstrated. Indeed, all cases that illustrate concepts that differ from the classic ones and from theoretical models may represent significant contributions to this volume.

Geological Classification of Canadian Gold Deposits by Knud Howard Poulsen,F. Robert,B. Dubé,Geological Survey of Canada Pdf

This bulletin proposes a geological classification of lode gold deposits based largely on the nature of the ore and on the geological settings of the deposits. Sixteen common types of bedrock gold deposits are distinguished and their main geological attributes are summarized. These do not correspond to an equal number of genetic types; many of these deposit types represent different components of larger hydrothermal systems and are genetically related. Most of the deposit types identified are represented by at least one large example (containing over 100 tonnes of gold). Descriptions are provided of Canadian gold deposits, including Archean & Proterozoic deposits in the Canadian Shield, Late Proterozoic to Palaeozoic deposits in the Appalachian Orogen, and Mesozoic to Cenozoic deposits in the Cordilleran Orogen. The final section discusses the application of gold deposit models.

Skarns in British Columbia by Gerald E. Ray,I. C. L. Webster,British Columbia. Ministry of Employment and Investment,British Columbia. Geological Survey Branch Pdf

Skarns in British Columbia have historically been important sources of iron, tungsten, copper, and gold. This publication begins with an introduction on skarn terminology and the problems of skarn identification. It then reviews a genetic model of skarn formation and presents descriptive profiles of eight types of skarn deposits; describes the database of at least 735 skarn occurrences in the province, and the number and distribution of skarns in British Columbia according to their associations, class, age, and distribution; and notes the ages of British Columbia skarns and the total production of various metals extracted from British Columbia skarns. Subsequent sections provide information on assays and metal ratios of mineralized skarns, skarn mineralogy, skarn mineral chemistry, chemistry of skarn-related intrusions, and the mapping and evaluation of skarns. The appendix contains a listing of 735 skarn occurrences in British Columbia, giving deposit name, MINFILE number, latitude/longitude, elements and minerals present, and associated rocks and their ages.
