The widespread mafic-ultramafic complexes in the Earth are well-known as their hosting Ni-Cu-PGE ore deposits, and their petrogenesis and mineralization have become hot issues in the geological studies. This thesis comprehensively investigated the petrology, mineralogy, geochemistry and geochronology of several mafic-ultramafic complexes in the Beishan Terrane, southern Central Asian Orogenic Belt aimed at systematically determining the mineralization and petrogenetic processes responsible for the formation of the complexes and placing constraints on the tectonic evolution of the Eastern Tianshan and Beishan, and the Early Permian mantle plume. The thesis identified mineralizing indicators of Ni-Cu sulfide deposits and defined the roles of partial melting, fractional crystallization, crustal assimilation and magma injection. The systematical isotopic compositions revealed the mantle source of the mafic-ultramafic complexes had undergone the subduction-related modifications both from the South Tianshan Ocean and subsequently the Junggar Ocean, and that the complexes were emplaced in the period of 269-285 Ma coeval with the 280 Ma mantle plume event in the Tarim Craton. The results of this thesis provide new insights about the tectonic setting, magma evolution, ore genesis, and exploration implications of the mafic-ultramafic complexes in Central Asian Orogenic Belt.

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.

Convergent plate margins are important places for material and energy recycling of the Earth, in particular major sites for continental growth, reworking, and recycling. They exhibit as narrow belt structure in the rigid outer layer of the Earth, corresponding to subduction zones at lithospheric mantle depths and orogenic belts at crustal depths. The type, geometry, and thermal structure of subduction zones have critical impacts on subduction processes and nature of products, resulting in a variety of magmatic rocks and ore deposits at convergent margins. Identification and classification of the physical structure and chemical variation at convergent margins as well as confirming their correlation with specific subduction types and stages are of pivotality to understand the spatiotemporal interaction between asthenosphere and lithosphere in orogenic belts. For places where magmatic arcs get partially or entirely destroyed by surface and/or subduction erosion, adjacent sedimentary rocks are ideal geological records for paleotectonic reconstruction.

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.
