This edited volume dedicated to late Prof. P.S. Saklani addresses the multidisciplinary themes pertaining to role of tectonism and magmatism in Crustal Evolution and global distribution of metallic and non metallic mineral deposits. It gives valuable information on geodynamic evolution, structural, petrological, isotopic, metamorphic, geochemical and geochronological attributes of continental and oceanic crust and is challenging reassessments of the existing paradigms. It addresses the implication of magmatism, metallogeny and application of geochronological ages (U-Pb SHRIMP age, Lu-Hf isotopic system; detrital zircons).

Professor Vinod Kumar Singh is working on Precambrian geodynamics of Bundelkhand Craton and teaching at Bundelkhand University, Jhansi, India since November, 1999. He did Ph.D. in Geology from University of Delhi and worked on Structure and tectonics on Himalayan orogenic belts and worked on Plaeaomagnetism at Tubingen University, Germany as scientists and co-researcher with Prof. Erwin Appel in a collaborative project funded by German Research Council. He is working in collaboration with Institute of Geology, KRC, Petrozavodsk, Russia on geodynamic evolution of earth crust. Prof. Singh using integrated approach involving new and innovative methods, geological fields indeed represent both Archean/Proterozoic and Himalayan (and related) orogens, to understand the geodynamics of crustal evolution. He received ILTP and DST-RFBR projects to understand the global geodynamics by comparing the lithospheric structures and geodynamics of Bundelkhand Craton and Karelian Craton with Russian collaborators Prof. A.I. Slabunov and Prof. DrSc Sergei A. Svetov. Prof. Singh has published about sixty contributions in reputed journals, book chapters and also edited five books and journals. He is a member of editorial board of several journals.
