Abstract: The Archean basement rocks in Shandong Province are important components of the Eastern Block in the North China Craton, consisting predominantly of granitoid gneisses with minor mafic and felsic supracrustal rocks and charnockites. They are exposed, from west to east, in the Luxi Granite-Greenstone Terrane, Yishui Terrane and Jiaodong Terrane, of which the low-grade Luxi Granite-Greenstone Terrane has been well studied, whereas little work has been done on the medium- to high-grade Yishui and Jiaodong Terranes. Controversies have long surrounded the timing of crustal growth and tectonic setting of these two terranes. This project is designed to resolve these issues by integrating field investigations, petrography, geochronology, geochemistry and metamorphism of the Yishui and Jiaodong Terranes. New zircon U-Pb data from the major lithologies have revealed that the Jiaodong Terrane experienced multi-stage magmatism at 2.9 Ga, 2.7 Ga and 2.6-2.5 Ga followed by two metamorphic events at 2.50 Ga and 1.9-1.8 Ga, whereas the Yishui Terrane underwent single magmatism at 2.57-2.53 Ga followed by a single metamorphic event at 2.50 Ga. Zircon Hf isotopic data have revealed that the Jiaodong Terrane underwent juvenile crustal growth with significant ancient crustal material additions at 3.4-3.1 and 2.8-2.7 Ga, while the Yishui Terrane experienced juvenile crustal growth with significant addition of crustal material at 2.8-2.7 Ga. Both the Jiaodong and Yishui Terranes experienced crustal reworking with minor juvenile additions at 2.6-2.5 Ga. Whole-rock compositions and Nd isotopes from the Jiaodong granitoid gneisses suggest that their protoliths are typical Archean tonalitic-trondhjemitic-granodioritic (TTG) suite. They are high in SiO2, Al2O3, Na2O, Sr and Sr/Y ratios, but low in MgO, K2O, TiO2, Cr, Ni, Y and Mg#. They are generally enriched in light rare earth elements and large ion lithophile elements, depleted in heavy rare earth elements and high field strength elements, with slight Eu anomalies. Two groups of granitoid gneisses have been recognized: low- and high-HREE groups, of which the former was generated from partial melting of metabasaltic rocks leaving eclogite in the residue, whereas the latter was formed by partial melting of metabasaltic rocks leaving garnet-amphibolite in the residue. Whole-rock Nd isotopes reveal that the protoliths of Mesoarchean granitoid gneisses were derived mainly from juvenile sources, whereas the early Neoarchean granitoid gneisses were derived from juvenile sources with significant additions of crustal material and the late Neoarchean granitoid gneisses were mainly derived from continental crustal sources. These features indicate that the protoliths of the Jiaodong granitoid gneisses were possibly formed by partial melting of thickened lower crust related to underplating of mafic magmas. Mafic granulites ( 2.50 Ga) of the Yishui Terrane show three distinct mineral assemblages corresponding to the pre-peak, peak and post-peak metamorphic stages, with P-T conditions constrained at 660-730℃/

Book excerpt: Focusing on issues of when and how Archean crust in the craton was formed, this PhD thesis book presents major research outcomes of field based metamorphic, geochemical and geochronological investigations on Meso-Neoarchean basement rocks from Shandong Province in the Eastern Block of the North China Craton. Based on major findings and new data, the author proposes that the formation and evolution of Archean crust was governed by mantle plumes, not by plate tectonics. As one of the oldest cratonic blocks in the world containing rocks as old as 3.85 billion years, the formation and evolution of North China Craton is still controversial. Therefore this book will be of value to anyone interested in the evolution of cratonic blocks and Precambrian geology.

Book excerpt: This thesis presents geological, petrological, geochemical, and zircon U–Pb–Lu–Hf isotopic field data for representative Precambrian lithologies in the Western Liaoning-Northeastern Hebei Provinces along the northern margin of the North China Craton (NCC). It describes late Neoarchean (2.64–2.48 Ga) supracrustal metavolcanic rocks and granitoid gneisses; late Paleoproterozoic (1.72–1.68 Ga) Jianping alkaline plutons and Pinggu alkaline volcanic rocks; and newly discovered ~1.23 Ga mafic dykes. The nature of magma sources and genesis of each magmatic episode are investigated, and the Precambrian (~2.6–1.2 Ga) lithospheric mantle evolution and crust-mantle interaction processes are established for the first time –aspects that provide important constraints in our understanding of the Precambrian crustal evolution and geodynamic processes in the region studied.

Available in PDF, EPUB and Kindle. Book excerpt: The Proterozoic aeon involved at least three major continental readjustments. India and Antarctica appear in most models of supercontinent reconstructions, but their relative position has been the subject of debate. High-resolution petrological and geochronological data, especially from the Proterozoic mobile belts, provide the principal means of resolving this issue. The ice-covered nature of Antarctica allows only limited access to the rocks, and then only in coastal tracts, so detailed studies in more accessible Proterozoic terrains in India assume added significance. This volume, a follow-up to the XII International Symposium on Antarctic Earth Science, Goa (a SCAR symposium), provides new data from selected locations in east Antarctica (Enderby Land and Dronning Maud Land) and from India, including the Eastern Ghats Mobile Belt (EGMB), Chota Nagpur Gneissic Complex, the Khasi Hills and the Aravalli–Delhi Mobile Belt. The presented geochronological data, constrained by petrological studies, are expected to provide new insights, especially into the EGMB–east Antarctica connection and the rate of continental readjustments in the post-Rodinia break-up.

Available in PDF, EPUB and Kindle. Book excerpt: The continental crust is our archive of Earth history, and the store of many natural resources; however, many key questions about its formation and evolution remain debated and unresolved: What processed are involved in the formation, differentiation and evolution of continental crust, and how have these changed throughout Earth history?How are plate tectonics, the supercontinent cycle and mantle cooling linked with crustal evolution?What are the rates of generation and destruction of the continental crust through time?How representative is the preserved geological record? A range of approaches are used to address these questions, including field-based studies, petrology and geochemistry, geophysical methods, palaeomagnetism, whole-rock and accessory-phase isotope chemistry and geochronology. Case studies range from the Eoarchaean to Phanerozoic, and cover many different cratons and orogenic belts from across the continents.

Book excerpt: The integration of Tectonics/Geochemistry, up-to-date reviews by leading scientists as well as a broad topical coverage of the Archean, are some of the features of this particular volume. As geochronology has progressed in the last 20 years, the Archean has continued to attract interest. Advancements in the understanding of Archean crustal and mantle evolution have progressed rapidly since the first International Archean Symposium in Western Australia (1970). The landmark for the Archean was the NATO Advanced Study Institute at Leicester (1975). At this meeting the Archean truly "came of age". Investigators from many different disciplines focused their expertise on the early history of the earth. For the first time, the nature of the atmosphere, oceans, and life during the Archean was an important part of an Archean symposium. During the most recent Archean Symposium in Perth in 1990, there was a shift in interest from field and trace element data to the new rapidly evolving high-precision U/Pb geochronology of Archean rocks and to detailed structural studies of both low and high grade Archean terrains. The terrane concept so widely applied to the Phanerozoic was proposed for the Archean Yilgarn Province in Western Australia and is now widely accepted for the Archean (as evident by the articles in this book). Plate tectonics is now widely accepted as the principal process that controls the history of continents and oceans. There are, though, well substantiated differences between Archean and post-Archean rocks that indicate that Archean tectonic regimes must have differed in some respects from modern ones. The question of how and to what degree did Archean plate tectonics differ from modern plate tectonics is treated in many of the chapters of this book. Altogether, the editor has presented a selection of articles that provide a fascinating insight into the latest observations in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Petrology, 6: Trondhjemites, Dacites, and Related Rocks focuses on the geology, geochemistry, and petrology of several kinds of trondhjemites, dacites, and genetically related rocks. The selection first elaborates on the definition, environment, and hypotheses of origin of trondhjemite; a review of the mineralogy and chemistry of tertiary-recent dacitic, latitic, rhyolitic, and related salic volcanic rocks; and some trace elements in trondhjemites and their implications to magma genesis and paleotectonic setting. Discussions focus on tectonic environments and trace element patterns, selection and reliability of trace elements, interrelationships between mineralogy and chemistry, and regional variations of dacitic and rhyolitic magmas. The publication then tackles strontium isotope geochemistry of late Archean to late Cretaceous tonalites and trondhjemites; Archean gray gneisses and the origin of the continental crust in West Greenland; and metamorphic development of early Archean tonalitic and trondhjemitic gneisses in Saglek Area, Labrador. The book examines the petrology, geochemistry, and origin of the Sparta quartz dioritetrondhjemite complex; reconnaissance geochemistry of Devonian island-arc volcanic and intrusive rocks in West Shasta District, California; and origin of the Twillingate trondhjemite in North-Central Newfoundland. The selection is highly recommended for geologists and geochemists wanting to explore trondhjemites, dacites, and genetically related rocks.

Book excerpt: Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments; they are commonly encountered in the continental crust. Until now, many geologists have been deterred from working with migmatites because of their complex appearance and an unhelpful non-genetic nomenclature. In his Atlas of Migmatites, Dr. Edward Sawyer provides genetically based definitions and a system of nomenclature with which it will be possible to describe and map migmatites effectively and to understand how combinations of factors and processes produce a bewildering morphological diversity. Migmatites are produced by partial melting; to aid the reader in the identification of migmatites, the author describes and illustrates microstructures that can be used to infer the presence of melt or a melt-producing reaction. He also describes how geochemical data can be used to infer petrological processes involved in migmatite development. This book includes the results from two decades of research in whole-rock geochemistry, partial melting, microstructural analysis and experimental deformation of partially molten rocks. It contains information from an outcrop through to a grain scale. Exceptionally well illustrated, with 272 colour plates and accompanying detailed captions, the Atlas provides descriptions and analyses of migmatites not previously available.
