DOWNLOAD EBOOK →This volume is a tribute to the career of J. Brendan Murphy and features papers by over 100 authors from countries all over the world: a testament to the high-profile and far-reaching influence of Brendan’s work. The topics covered fall into three broad categories that encompass Brendan’s main fields of influence: (1) supercontinents and the supercontinent cycle, including reconstructions and modelling; (2) orogenesis and terranes, with a focus on the Appalachian–Variscan and Central Asian orogenic belts and the oceans with which they are associated; and (2) magmatism and magmatic processes, centring on the geochemistry and isotopic compositions of magmas in arc and rift setting. Like Brendan’s own research, the scope of the papers spans the globe and ranges from strongly field-based studies to conceptual analyses. All of the articles, however, are focused on unravelling some critical aspect of geology or aimed at clarifying some crucial geological process. Hence, they also share a theme common to Brendan’s many contributions in emphasizing the importance of process-oriented research.

DOWNLOAD EBOOK →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.

It takes the reader along a clockwise path around the North Atlantic Ocean from the U.S. and Canadian Appalachians; to the Caledonides of Spitsbergen, Scandinavia, Scotland and Ireland; and thence south to the Variscides of Morocco"--

DOWNLOAD EBOOK →Dedicated to Bob Hatcher, this Memoir explores linkages between tectonic processes through a series of field-, numerical- and laboratory-based studies, concentrating on feedback mechanisms within ancient and evolving orogens by which individual or linked tectonic processes may influence or predetermine the operation of other processes in space and time. Case studies cover a wide range of ancient to modern orogens: the Svecofennian of southern Finland, the Gyeonggi Massif of Korea, the Caledonides of northern Scotland, the Variscan of the East European craton, the Appalachians of the eastern United States, the European Alps and Dinarides, north Cascades of the northwestern United States, and the Himalaya. Emphasis is placed on integration between data sets developed from a wide range of analytical approaches, including: field mapping, seismic reflection profiling, strain analyses, petrology, isotopic dating, and numerical modeling-based studies of thermal evolution associated with tectonic processes such as thrust-related burial and exhumation.

The region features a tectonically erosive forearc, protracted arc magmatism, a high-elevation hinterland plateau and strongly shortened retroarc thrust belt, and a Paleocene-Recent foreland basin system"--
