Orogenic-Type Polymetallic Mineralization Associated with Multistage Orogenesis in Northern North China Plate
Author: Wenbo LiPublisher: Springer Nature
ISBN: 981161346X
Category : Science
Languages : en
Pages : 166
Book Description
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.
Paleozoic and Mesozoic tectonic evolution of central and eastern Asia
Author: Gregory Arlen DavisPublisher: Geological Society of America
ISBN: 9780813711942
Category : Science
Languages : en
Pages : 612
Book Description
Hendrix (geology, U. of Montana) and Davis (earth sciences, U. of Southern California) present 19 articles detailing ground-based work on the history of assembly and intracontinental deformation of central and eastern Asia. Chapters look at the structural, thermochronologic, and sedimentary records of the history of Paleozoic assembly in Mongolia and central and western China. Further information is presented on Mesozoic deformation in orogenic belts of central and eastern Asia. Asia's sedimentary basins are examined and the intracontinental deformation they record is documented. Many of these contributions, particularly the papers examining Mongolian geology, are the first ground-based articles written in English. Annotation c. Book News, Inc., Portland, OR (booknews.com)
Polymetallic Metallogenic System
Author: Liqiang YangPublisher: MDPI
ISBN: 3039212931
Category : Science
Languages : en
Pages : 538
Book Description
Within the last decade, the high and continuing demand for precious and base metals, as well as critical elements, has prompted a global rush on a scale never before seen. This eventually resulted in the demand for considerable innovation and improvement in mineral deposit genetic modelling and ore formation regimes for the many different types of gold deposits, now recognized, and paralleled by the wide employment of exploration techniques and a rapid expansion of geological databases. This Special Issue will show case studies of porphyry polymetal systems, orogenic gold formations, water–rock reaction, ore-forming structure evolution, mineralogy and petrology of ore deposit, ore formation regime, geochronology and geochemistry of ore deposit, ore-forming evolution, mineral exploration and cutting-edge technology in ore deposit study.
Subduction and Closure of the Palaeo-Asian Ocean along the Solonker Suture Zone: Constraints from an Integrated Sedimentary Provenance Analysis
Author: Paul R. EizenhöferPublisher: Springer Nature
ISBN: 9813292008
Category : Science
Languages : en
Pages : 270
Book Description
This Ph.D. thesis attempts to decipher the closure of the Palaeozoic Palaeo-Asian Ocean along the enigmatic Solonker Suture in East Asia adopting a methodology that integrates geochemical and geochronological data from Palaeozoic sedimentary and volcanic rocks in the region. It provides an in-detail but also broad insight into the Palaeozoic to early Mesozoic tectonic evolution of the region, not only pin-pointing the debated location of the Solonker Suture but also the timing of final disappearance of the Palaeo-Asian Ocean during Permian to Early Triassic times. The results have led to propose a tectonic ‘soft-collision’ model for the amalgamation of the North China Craton and the Mongolian Terranes in northern Asia explaining the general absence of geologic features characteristic for continent-continent collisions such as the occurrence of regional-scale high-grade metamorphic rocks, ophiolite belts and fold-thrust structures. This new model may serve as a blueprint for the tectonic evolution of similar suture zones that are characterized by the absence of typical collision related lithologies and structures. The thesis is particularly useful as a guide for researchers who seek an in-depth understanding of the Palaeozoic to early Mesozoic tectonic evolution of northern China and Central Asia along the Solonker Suture.
