Book Description
Continuing the tradition of International Dyke Conference, this book is largely based on contributions from the IDC7 but also includes some chapters by invitation. It focuses on mafic dyke swarms and related associations: e.g. links with sills, kimberlites, syenites, carbonatites, and volcanics, discussing the following themes: (i) regional maps/reviews of dyke swarms and related units, (ii) the role of giant dyke swarms in the reconstruction of supercontinents/paleocontinents, (iii) mapping of dykes using remote sensing techniques, (iv) geochronology of dyke swarms, (v) petrology, geochemistry and petrogenesis of dykes, (vi) emplacement mechanism of dykes, (vii) dyke swarms and planetary bodies, and (viii) links to mineralization and resources.

Book Description
Whilst the earlier studies on Indian dykes were largely of descriptive nature, subsequent ones have been sporadic and as such very few compilations exist. The principal purpose of this volume is to provide state-of-the-art information on the geochemistry, geophysics and geochronology of the dyke rocks of India in space and time.

Book Description
Often seen as ethnically monolithic, the African Methodist Episcopal (AME) Church in fact successfully pursued evangelism among diverse communities of indigenous peoples and Black Indians. Christina Dickerson-Cousin tells the little-known story of the AME Church’s work in Indian Territory, where African Methodists engaged with people from the Five Civilized Tribes (Cherokees, Creeks, Choctaws, Chickasaws, and Seminoles) and Black Indians from various ethnic backgrounds. These converts proved receptive to the historically Black church due to its traditions of self-government and resistance to white hegemony, and its strong support of their interests. The ministers, guided by the vision of a racially and ethnically inclusive Methodist institution, believed their denomination the best option for the marginalized people. Dickerson-Cousin also argues that the religious opportunities opened up by the AME Church throughout the West provided another impetus for Black migration. Insightful and richly detailed, Black Indians and Freedmen illuminates how faith and empathy encouraged the unique interactions between two peoples.

Book Description
The Indian shield represents a vast repository of the Palaeoproterozoic geological record. Built over the four large amalgamated Archaean nuclei (Dharwar, Bastar, Singhbhum and Aravalli-Bundelkhand) the major and minor Palaeoproterozoic sedimentary basins and supracrustal sequences in India are comparable in scale, and perhaps also in development, to those of North America, Africa, Australia and Brazil. The deformation of these supracrustal sequences, attendant metamorphism and emplacement of plutonic bodies hold important clues to their connection with major orogenies. Research in these areas has led to investigations into global correlation, which in turn has had a direct bearing on refining models of Palaeoproterozoic supercontinent assembly and break-up. This book covers various aspects of regional geology as well as broader issues of the Indian Palaeoproterozoic geology and its global context. It is an outcome of the UNESCO-IGCP 509 Palaeoproterozoic Supercontinents and Global Evolution research project.

Book Description
This Memoir provides a comprehensive review of the Precambrian basins of the four Archaean nuclei of India (Dharwar, Bastar, Singhbhum and Aravalli-Bundelkhand), encompassing descriptions of the time-space distribution of sedimentary-volcanic successions, the interrelationship between tectonics and sedimentation, and basin histories. Studies of 22 basins within the framework of an international basin classification scheme deepen an understanding of the basin architecture especially for cratonic basins. Most Indian sedimentary successions formed as cratonic to extensional-margin rift and thermal-sag basins, some reflecting mantle plume movement, subcrustal heating or far-field stress. This Memoir shows that Phanerozoic plate-tectonic and sequence stratigraphic principles can be applied to the Precambrian basins of large Archaean provinces. The differences between the stratigraphic architecture of the Indian Precambrian and examples of Phanerozoic basin-fill successions elsewhere are ascribed to variable rates and intensities of the controls on accommodation and sediment supply, and changes inherent in the evolution of the hydrosphere-atmosphere and biosphere systems.

Book Description
Dyke swarms are remnants of large igneous provinces, and are pointers of continental break-up events, as well as indicators for ancient continental reconstructions. These global geodynamic aspects are of crucial significance in tectonics, and with recent developments in high-precision age, dating it has become possible to enter these short-lived ma

Book Description
Granitoids form the bulk of the Archean continental crust and preserve key information on early Earth evolution. India hosts five main Archean cratonic blocks (Aravalli, Bundelkhand, Singhbhum, Bastar and Dharwar). This book summarizes the available information on Archean granitoids of Indian cratons. The chapters cover a broad spectrum of themes related to granitoid typology, emplacement mechanism, petrogenesis, phase-equilibria modelling, temporal distribution, tectonic setting, and their roles in fluid evolution, metal delivery and mineralizations. The book presents a broader picture incorporating regional- to craton-scale comparisons, implications for Archean geodynamic processes, and temporal changes thereof. This synthesis work, integrating modern concepts on granite petrology and crustal evolution, offers an irreplaceable body of reference information for any geologist interested in Archaean Indian granitoids.

Book Description
Dykes occur in a wide variety of geological and tectonic settings and their detailed study through space and time is imperative for understanding several geological events. Dykes are believed to be an integral part of continental rifting and when they occur as spatially extensive swarms of adequate size, they can be of immense utility in continental reconstructions and also help to identify Large Igneous Provinces (LIPs). It is known that continental flood basalts and major dyke swarms have their origin related in some way to the up-rise of hot mantle plumes which may lead to rifting and eventual continental break-up. Dykes signify crustal extension and are important indicators of crustal stabilisation events, supercontinental assembly and dispersal, crust-mantle interaction and play a significant role in the delineation of crustal provinces as well as in deciphering crustal evolution events. Many economic mineral deposits of the world are also associated with a variety of dykes. The volume will provide state-of-the-art information on all aspects of dykes with emphasis on the origin, evolution and emplacement of dykes.

Book Description
Paleoproterozoic to Cenozoic lamprophyres, lamproites and related rock types (e.g., orangeites, kimberlites) are volatile-rich mafic magmatic rocks with a unique potential for the investigation of processes affecting mantle reservoirs. They originated from primary mantle-derived melts that intruded both cratons and off-craton regions, which were parts of former supercontinents – Columbia, Rodinia and Gondwana–Pangea. Well-known for hosting economic minerals and elements such as diamonds, base metals, gold and platinum-group elements, they are also significant for our understanding of deep-mantle processes, such as mantle metasomatism and mantle plume–lithosphere interactions, as well as large-scale geodynamic processes, such as subduction-related tectonics, and supercontinent amalgamation and break-up. This book aims to provide a timely overview of the state-of-the-art and recent advances as achieved by various research groups around the world. Mineralogical, geochemical, geochronological and isotope analyses are used to decipher the complex petrogenesis and metallogenesis of these extraordinary rocks, and unravel a complete history of tectonic events related to individual supercontinent cycles.
