Dyke Swarms of the World: A Modern Perspective

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.

Prof. Rajesh K. Srivastava is a Professor of Geology at Banaras Hindu University. His specialization fields are Igneous Petrology, Geochemistry and Precambrian Geology, and his main interests are in: i. Precambrian Mafic Igneous Complexes, particularly dyke swarms and associated volcanic rocks from the Bastar craton, Dharwar craton and Arunanchal Himalayaii. UltramaficAlkalineCarbonatite Complexes of western, southern, and northeastern Indiaiii. Lamprophyres, lamproites, and kimberlites of the Mahakoshal supracrustal belt and Bastar craton (Central India), Damodar valley, East Gondwana (Eastern India), and Eastern Dharwar craton, andiv. the Andaman Ophiolite suite Prof. Richard Ernst is a Scientist in Residence at Carleton University, Ottawa, Canada and a Guest Professor at Tomsk State University (TSU), Siberia, Russia. His research is focused on all aspects of Large Igneous Provinces (LIPs) and links with mineral, metal and hydrocarbon resource exploration, supercontinent breakup, catastrophic environmental/climate change including mass extinction events, and planetary analogues. He is the author of Large Igneous Provinces, published in 2014 by Cambridge University Press. Prof Peng Peng is currently working at the Institute of Geology and Geophysics, Chinese Academy of Sciences. He is a petrologist and geochemist interested in using mafic dyke swarms, greenstone belts and other associated records to reveal the forming and early evolution of the continental crust and the lithosphere, as well as the palaeogeography of Precambrian supercontinents.
