Evidence of Enriched, Hadean Mantle Reservoir from 4.2-4.0 Ga zircon xenocrysts from Paleoarchean TTGs of the Singhbhum Craton, Eastern India.
TL;DR: Time integrated ɛHf[t] compositional array of the Hadean xenocrysts indicates a mafic protolith with 176Lu/177Hf ratio of ∼0.019 that was reworked during ∼4.2-4.0 Ga, suggesting that separation of such an enriched reservoir from chondritic mantle took place at 4.2 Ga.
Journal ArticleDOI
Generation and evolution of Palaeoarchaean continental crust in the central part of the Singhbhum craton, eastern India
TL;DR: In this article, the authors presented whole-rock and mineral chemical data coupled with zircon U-Pb dating and Hf isotope results on granitoids from the central part of the Singhbhum craton to understand their petrogenesis, tectonic setting and role in continental crustal evolution.

Oldest rocks from Peninsular India: Evidence for Hadean to Neoarchean crustal evolution
M. Santosh,Qiong-Yan Yang,E. Shaji,M. Ram Mohan,Toshiaki Tsunogae,Toshiaki Tsunogae,Manavalan Satyanarayanan +6 more
TL;DR: In this article, the authors reported evidence for Hadean and Eoarchean crust from the fringe of the Coorg Block, one of the oldest crustal blocks in Peninsular India.
Journal ArticleDOI
Evidence for a Neoarchean LIP in the Singhbhum craton, eastern India: Implications to Vaalbara supercontinent
TL;DR: In this article, the authors reported eight new Pb-Pb baddeleyite ages and paleomagnetic results on a series of hitherto unknown NNE-SSW trending mafic dyke swarms intruding the Paleoarchean basement rocks in the Singhbhum craton, eastern India.

Early Proterozoic climates and plate motions inferred from major element chemistry of lutites
H.W. Nesbitt,Grant M. Young +1 more
TL;DR: The early Proterozoic Huronian Supergroup of the north shore of Lake Huron (Fig. 1) is a thick succession of sedimentary and volcanic rocks deposited between about 2,500 and 2,100 Myr ago as discussed by the authors.

Prediction of some weathering trends of plutonic and volcanic rocks based on thermodynamic and kinetic considerations
H.W. Nesbitt,Grant M. Young +1 more
TL;DR: In this paper, the proportions of Ca, Na and K released by feldspars of plutonic rocks (granites to gabbros) to weathering solutions were predicted.

U‐Pb geochronology of zircons from lunar breccia 73217 using a sensitive high mass‐resolution ion microprobe
TL;DR: In this paper, the age of four zircons from thin-sections of one highland breccia, 73217, using the recently constructed ion microprobe SHRIMP was determined.

H.W. Nesbitt,Grant M. Young +1 more
TL;DR: In this paper, the predicted bulk compositional changes are corroborated by studies of recent weathering profiles developed on a variety of plutonic and volcanic rocks under different climatic regimes.
