Magmatic and metamorphic history of Paleoarchean tonalite–trondhjemite–granodiorite (TTG) suite from the Singhbhum craton, eastern India
TL;DR: In this paper, texturally controlled dating of zircon from Paleoarchean tonalite-trondhjemite-granodiorites of the Older Metamorphic Tonalitic Gneisses and the Singhbhum Granite batholith (Phases I, II, and III) reveals a polycyclic evolution of the Archean crust.
Journal ArticleDOI
Proto-India was a part of Rodinia: Evidence from Grenville-age suturing of the Eastern Ghats Province with the Paleoarchean Singhbhum Craton
Sabyasachi Chattopadhyay,Dewashish Upadhyay,J. K. Nanda,Klaus Mezger,Kamal Lochan Pruseth,Jasper Berndt +5 more
TL;DR: In this paper, metamorphic and geochronological evolution of the Malayagiri supracrustal belt in the Rengali Province has been used to constrain the suturing of the Eastern Ghats Province with the Singhbhum Craton.
Journal ArticleDOI
Formation of Paleoarchean-Mesoarchean Na-rich (TTG) and K-rich granitoid crust of the Singhbhum craton, eastern India: Constraints from major and trace element geochemistry and Sr-Nd-Hf isotope composition
TL;DR: The 3.45-3.05-Ga Mayurbhanj granitoids are consistent with shallow plagioclase-bearing crustal sources and have similar trace-element characteristics as the 3.44-Ga TTGs as mentioned in this paper.
Proceedings ArticleDOI

Joshua E. Oppor,Matthew A. Bershady,Marsha J. Wolf,Michael R Smith,Sabyasachi Chattopadhyay,Kurt P. Jaehnig,Jeffrey W. Percival,Mark P. Mulligan,Kathleen M. Jurgella,Briana Wirag +9 more
TL;DR: In this paper , the authors present the results of the performance testing of various test cables as well as performance testing and end-to-end mapping of the fully-assembled science cable.
Proceedings ArticleDOI
Slit mask integral field units for the Southern African Large Telescope
TL;DR: In this paper , the authors describe the design, fabrication, assembly and characterization of a slit mask integral field unit (SMI) for the Robert Stobie Spectrograph's visible arm and the future red arm.
