TLDR
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.About:

Hugo K.H. Olierook,Chris D. Clark,Steven M. Reddy,Rajat Mazumder,Rajat Mazumder,Rajat Mazumder,Fred Jourdan,Noreen J. Evans +7 more
TL;DR: In this article, the authors report new zircon U-Pb and Hf isotopic data from key stratigraphic intervals in the Archean nucleus and the North Singhbhum Mobile Belt.

Uraniferous paleoplacers of the Mesoarchean Mahagiri Quartzite, Singhbhum craton, India: Depositional controls, nature and source of > 3.0 Ga detrital uraninites
Joydip Mukhopadhyay,Joydip Mukhopadhyay,Brundaban Mishra,Kalyan Chakrabarti,Saheli De,Gautam Ghosh +5 more
TL;DR: In this article, the detrital uraninite grains from the Mahagiri Quartzite were analyzed and compared to those from the Witwatersrand Au-U deposits. But the results showed that the U contents of the uraninites from the mines are significantly lower than that of the ideal stoichiometric composition of UO2.

Detrital Zircons Reveal Evidence of Hadean Crust in the Singhbhum Craton, India: A Reply
Scott R. Miller,Paul A. Mueller,Joseph G. Meert,George D. Kamenov,Anthony F. Pivarunas,Anup K. Sinha,Manoj K. Pandit +6 more
TL;DR: The Singhbhum craton is one of five Archean cratons constituting the Indian subcontinent and consists of four major lithotectonic units with broadly defined ages from Eoarchean to Neoarchea as discussed by the authors.

The Neoarchean-Paleoproterozoic basin development and growth of the Singhbhum Craton, eastern India and its global implications: Insights from detrital zircon U-Pb data
TL;DR: In this article, detrital zircon ages were obtained from five samples of widely separated locations of two parallel belts, which are known as the Northern and the Southern Supracrustal Belts.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.
Journal ArticleDOI
The geochemical evolution of the continental crust
TL;DR: A survey of the dimensions and composition of the present continental crust is given in this paper, where it is concluded that at least 60% of the crust was emplaced by the late Archean (ca. 2.7 eons).

The Lu–Hf and Sm–Nd isotopic composition of CHUR: Constraints from unequilibrated chondrites and implications for the bulk composition of terrestrial planets
TL;DR: In this paper, the Lutetium-Hafnium radiogenic isotopic system is used as a chronometer and tracer of planetary evolution, and the Lu-Hf system parameters need to be more tightly constrained, in particular the LuHf isotopic composition of the chondritic uniform reservoir and, by extension, the bulk silicate Earth.
