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.

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.

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.

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.

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.
