Abstract

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.

Abstract

This book is the first systematic treatise of available data and view-points obtained from geological and geochemical studies of the Mo deposits in Qinling Orogen, China. Qinling Orogen has a minimum reserve of 8.7 Mt Mo, ranking the largest molybdenum province both in China and the world. Incorporating all known Mo deposit types in the world, it presents extensive studies of Mo deposits of world-class and unusual types within tectonic settings. The Qinling Orogen was finally formed during continental collision between Yangtze and North China cratons, following the Triassic closure of the northernmost paleo-Tethys. It hosts 49 Mo deposits formed in seven mineralization events since 1850 Ma, with all the world-class deposits being formed during 160-105 Ma, coeval with collisional orogeny. These deposits are assigned to magmatic and metamorphic hydrothermal classes. The magmatic hydrothermal class includes porphyries, skarns, and intrusion-related veins (carbonatite, fluorite and quartz). The porphyry Mo systems in Qinling Orogen are predominated by Dabie-type formed in continental collision setting, followed by Endako- and Climax-types formed in continental arcs and rifts, respectively. The metamorphic hydrothermal Mo deposits are only reported in Qinling Orogen, and thus a new crustal continuum model for the orogenic class mineral systems is proposed. A scientific linkage between ore geology and fluid inclusions is introduced and verified both by theory and case studies. This is the first research book comprehensively displaying continental collision metallogeny. This literature will benefit both Western and Chinese mineral explorers and miners, as well as research scientists and students.

Abstract

This study investigated the writing performance of 19 participants on two social media networks (Renren and Facebook) and how social media can influence their writing performance. Participants in this study, 12 students from Shanghai International Studies University (SISU) and 7 Worldlearning students from China, were asked to fill out two questionnaires and complete four writing assignments on different themes over a period of 3 months. The dependent variables are the following: text productivity, syntactic accuracy, sentence complexity and spelling mistakes. The results show that neither the accuracy nor the productivity of students' texts can be greatly improved after using social media as a study platform over a period of 3 months and that the number of spelling mistakes made while writing with social media is higher than when students write in a traditional classroom context. What does improve is the complexity of the sentences students write. These findings, together with the feedback from the participants provide us with evidence that learning writing with social media still has a positive effect on writing performance. Furthermore, we find that teacher interventions are needed to correct errors in students' texts so as to help students improve their writing. What is more important is that students should be encouraged to interact with peers as much as possible so that they can acquire what they haven't mastered yet from reading others' texts. Keywords: improved writing performance, social media, interaction
