Structural relationships and SrNd isotope systematics of polymetamorphic granitic gneisses and granitic rocks from central Rajasthan, India: implications for the evolution of the Aravalli craton
TL;DR: A review of the state of the art of structural and geochronological knowledge of cratonic rocks in part of central Rajasthan, India, and contributions new observations and isotopic data on the structural features and age of granitic rocks in the area are presented in this paper.
Journal ArticleDOI
Geochemical and Sm–Nd isotopic characteristics of the Late Archaean-Palaeoproterozoic Dhanjori and Chaibasa metasedimentary rocks, Singhbhum craton, E. India: Implications for provenance, and contemporary basin tectonics
Shuvabrata De,Shuvabrata De,Rajat Mazumder,Rajat Mazumder,Tohru Ohta,E. Hegner,K. Yamada,Tapas Bhattacharyya,Jeffrey R. Chiarenzelli,W. Altermann,Makoto Arima +10 more
TL;DR: In this paper, the authors present geochemical and Sm-Nd isotopic data from the Dhanjori and Chaibasa Formations for the first time and combine previous sedimentological data with the goal to expand the framework for understanding the depositional and tectonic setting of these two formations.
Journal ArticleDOI
Structural evolution of a gneiss dome in the axial zone of the proterozoic south Delhi fold belt in central Rajasthan
TL;DR: The structural geometry of the Anasagar gneiss dome in the axial zone of the South Delhi Fold Belt is controlled by polyphase folding as mentioned in this paper, and it is classified as a thrust-related gniiss dome and not as a metamorphic core complex.
Journal ArticleDOI
Analysis of superposed strain: A case study from Barr Conglomerate in the South Delhi Fold Belt, Rajasthan, India
TL;DR: The structural geometry in the Barr conglomerate and the neighboring rocks in the western flank of the Meso- to Neoproterozoic South Delhi Fold Belt indicate superposed deformation, with structures developed by horizontal dextral simple shear deformation superimposed on earlier structures formed during approximately ESE-WNW compression and subvertical maximum elongation.
Journal ArticleDOI
Interaction between felsic granitoids and mafic dykes in Bundelkhand Craton: A field, petrographic and crystal size distribution study
Tanwita Deb,Tapas Bhattacharyya +1 more
TL;DR: In the Bundelkhand Craton of central India, mafic dykes intruded when granitoids was partly crystallized as mentioned in this paper, and textural evidence of mingling is represented by acicular apatite morphologies, titanite-plagioclase ocelli and ophitic-subophitic texture.
