The earth crustal growth since its formation still need in depth research which evolves a wide range of geological processes including plate tectonics and magmatic on which man life existing. Therefore, this special volume planned after organising three International Conferences on Precambrian Continental Growth and Tectonism, in 2005, 2009 and 2013 at the Institute of Earth Sciences of Bundelkhand University, Jhansi, India, for the vitality of interactive platforms which provide scholars with the much- needed opportunities for closer interaction and thought exchange. The proceedings of these conferences had incorporated the great ideas and achievements from scientists, acting as a valuable source for advance research [1-3]. This thematic issue contains 19 research articles on geodynamic evolution of earth, geomorphology, structural, petrologic, isotopic, tectonic, and geochemistry investigations related to the earth crust and its economic importance for society.

The first paper is by S.A. Svetov et al. discuss the key magmatic systems including the komatiite-basalt and site which play an important role in the Arche a crust-forming processes, particularly in the accretion collision processes, probing from Karelian craton. The mafic rocks formed large allochth on complexes on the continental margin that resulted in the increasing of the continental crust thickness. Subduction of separate plates caused the formation of adakitic and bajaitic assemblages during its melting and basalt - andesite - dacite- rhyolite and tonalite- trondhjemite-granodiorite complexes in the processes of mixing with mantle wedge.

Lobach Zhuchenkoet SB et al. focus on U-Pb and Lu-Hf isotopic analyses on a zoned peridotite lens occurring in the orthogenesis of the Ukrainian shield which show evidence of magmatic origin of zircon. The εHf (2.8Ga) of zircon varies from 8.5 to 10.7 and indicates that the ultramafic melt contained an old component probably assimilated from the host orthogneiss.

Kuznetsovet NB et al. discuss sources of Early Precambrian Ordovician terrigenous rocks of the Sol-Iletsk archis, East European platform, Russia after comprehensively U-Pb age, Hf-isotope and trace-elements studies. They found that the primary detrital zircons were most likely sourced from the crystalline complexes of the Late Proterozoic Volgo-Sarmatian and Taratash orogens and Archean Volga-Uralia basement which is atypical for the southeastern part of the East European platform. Goroshko MV et al., presents highgrade uranium-tantalum-niobium ores occur in the Arbarastakh massif of alkaline ultrabasic rocks of Proterozoic age and estimated two types of metasomatic processes in the region. Slabunov AI and Singh VK reviews the Indian crustal evolution of Bundelkhand and Dharwar craton in Archean time and show that each of the cratons displays its own crust formation pattern.

1. Slabunov et al. established that compositional characteristics of the Ikauna intrusionsare well-differentiated complex comprising dunite (serpentinite), pyroxenite, gabbro and gabbro-pegmatite rocks in Bundelkhand craton, India. The metagabbro are enriched by Rb and Ba and positive Sr and Eu anomalies, expected for the presence of cumulus plagioclase whereas metadunites and metapyroxenites show lower trace element abundances and negative Sr anomalies, related to fractional crystallization of plagioclase. These complexes have similar characteristic with the layered intrusions of the peridotitegabbronorite complex of the Karelian craton.

2. Neupane evaluates detrital zircon U-Pb dating of the Tansen basin foreland sedimentary formations from Central Nepal and indicates that the spectra with a common pattern of major age peaks clustered at ~500-750Ma, 800-1200Ma, ~1830Ma and ~2500Ma.

Singh Y present granite-pegmatite systems of the Bastar craton, India for host polymetallic Nb, Ta, Sn, Be, Li, ore deposits, which are genetically related to various granitic bodies suggest a crustal origin. Manuvachari TB et al. suggests that the greywackes from Dharwar craton, India were derived from an evolved continental crust source which had felsic to intermediate composition, with a moderate relief exposed to arid and dry palaeoclimatic conditions and were deposited in a subduction related forearc basin.

Devi SK and Thomas H discusses petrography and geochemistry of gneissic rocks from central Rajasthan, India as they were coarse-grained, light colored exhibiting well augen gneissic characteristics alumina rich and high in potash content. These augen gneisses were found to be originated from granite to granodioritic igneous parentage of calc-alkaline composition in the tectonic setting of within plate granite. Shahnawaz et al., present mineral compositions of the Meso-Neoproterozoic Sandstones from Chittorgarh, Rajasthan, India which have chief abundant of plutonic quartz originated mainly from granitic batholiths or granite-gneisses and the modal analysis suggested the product of multiple sources, including plutonic basement, sedimentary and metasedimentary rocks.

Lata S et al. discuss the geometry of folds in Mandhali Formation rocks occur in Inner Sedimentary Zone of Lesser Himalaya, which exposes complexly folded and refolded structures. They indicate that the shearing and strain patterns are most dominant folding mechanism, has been the flexure-shear for the folds which are overprinted by the fold flattening and other subsequent deformations, on the basis of geometric analysis using dip isogon and orthogonal thickness parameters.

Banerji DC et al. discuss about Sausar Stratigraphy in central India on the basis of contact metamorphic assemblages in calcareous met sediments and their ubiquitous presence, as lenses, along with the presence of numerous smaller metacarbonates patches, well within the surrounding gneiss further strengthens the possibility of the biotite gneiss being intrusive within the calcareous rocks of Sausar Group.

Mir AR and Alvi SH report geochemical characteristics of the ultramafic dykes, Singhbhum craton, India, that they are picritic in nature and show arc related tectonic setting formed by subduction related basaltic rocks. Singh PK explains Platinum Group of Metals occurrence in ultramafic and associated rocks from south part of Bundelkhand Craton, India and has good potential for a PGM deposit may be associated with plume/ super plume activity during crustal evolution of the craton.

Singh VK et al. point out that the low-grade banded iron bearing rocks are occurring around Babina, Mauranipur and Girar area in Bundelkhand craton, India may be potential source of iron. The BIF of the Kostomuksha greenstone belt of the Karelian craton is very similar to the BIF of the Mauranipur greenstone belt but without extreme Mn concentrations. This BIF was probably formed in a four-arc basin supplied with terrigenous material and indicate that the composition of BIF is a sensitive indicator of geodynamic settings.

Mishra S et al. discuss geodynamic settings of Neoarchean granodiorite-granite series rocks which suggest subduction tectonic setting formed in active continental edge where oceanic crust subducted under continental block by accretion-collision system. The plagioclase-orthoclase granite produced due to anhydrous partial melting of the Paleo-Mesoarchean TTG or mafic crustal materials in an extensional regime after post-accretionary processes.

Kaplay RD et al. reported an outline of the morphometric and structural studies from western margin of East Dharwar craton, India, have strike-slip fault characteristics and the elongation ratio of the sub-basins suggests tectonically active. Mir AR investigated the Panjal volcanics from Kashmir valley and found mostly basalts and basaltic andesites in nature showing primary volcanic features as vesicles, pillow structures, columnar joint patterns and amygdule structures occur in sub-aqueous as well as continental/sub-aerial volcanic rocks and had experienced stress due to Himalayan orogeny.


I express my sincere thanks Prof. Singh MM, Head of the Department of Geology, Bundelkhand Univeisity, Jhansi, India for providing the necessary facilities to complete this thematic issue and all contributors in this volume and very well-wishers for their help in many ways. This special issue will be useful for geologists, academics, research scholars and also for those interested in problems of the earth crust evolution history.
