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.

Chiral Phosphorous Based Ligands in Earth-Abundant Transition Metal
Catalysis summarizes the most significant progress in the field of
chiral phosphine ligand chemistry and a broad range of
earth-abundant transition metal/chiral phosphine ligand-catalyzed
enantioselective transformations. The book provides an
authoritative and in-depth understanding of important topics about
asymmetric catalysis based on earth-abundant transition
metals/chiral phosphine ligands, making it ideal for organic
chemistry researchers working in the field of asymmetric catalysis,
synthetic methodologies and total synthesis. The development of new
chiral phosphine ligands to achieve precise stereo control in many
earth-abundant transition metal-catalyzed reactions is a very
important field in organic synthesis, materials science and
medicinal chemistry. The asymmetric synthesis promoted by
transition metal/chiral phosphine ligands provides one of the most
ideal ways to produce valuable optically active chemicals.
