U-Pb Neoproterozoic age and petrogenesis of a calc-alkaline shoshonitic lamprophyre from Simdega area, Chhotanagpur Gneissic Complex (Eastern India): Implication for the evolution of the Central Indian Tectonic Zone and Rodinia tectonics
Deepak Kumar,N. V. Chalapathi Rao,Aparajita Tripathi,B. Belyatsky,Priyesh Prabhat,Waliur Rahaman,Manavalan Satyanarayanan +6 more
TL;DR: In this article , the authors presented petrology, U-Pb SHRIMP apatite and titanite ages and bulk-rock Sr-Nd isotope data for an unmetamorphosed and undeformed lamprophyre dyke from the Simdega area of the Chhotanagpur Gneissic Complex (CGC) which is a component of the E-W trending Central Indian Tectonic Zone (CITZ), India.

Petrology, geochemistry and U–Pb zircon geochronology of Fe–Ti oxide ore‐bearing mafic sill from Saltora‐Mejia area of Chotanagpur Granite Gneissic Complex, eastern India: Implication for late tectonic emplacement of mafic rock of E‐MORB nature in an orogenic belt
Riya Mondal,Arijit Ray,Tushar Mouli Chakraborti,Kosuke Kimura +3 more
TL;DR: A mafic sill in eastern India's Chotanagpur Granite Gneissic Complex exhibits E-MORB geochemical character and a 960 Ma U-Pb zircon age, suggesting late tectonic emplacement in an orogenic belt, possibly facilitated by delamination and asthenospheric upwelling.

Petrology, U-Pb titanite dating and Sr-Nd isotope geochemistry of a shoshonitic lamprophyre dyke near the Western Dharwar Craton-Southern Granulite Terrane contact, southern India: Implications for long-lived enriched mantle, widespread Tonian-Cryogenian rifting, and Rodinia configuration
Sneha Raghuvanshi,N.V. Chalapathi Rao,D. Talukdar,B. Belyatsky,Priyesh Prabhat,Waliur Rahaman,B. Lehmann,J.G. Meert +7 more
TL;DR: A shoshonitic lamprophyre dyke in southern India yields a 820 ± 15 Ma U-Pb titanite age, indicating a Tonian origin from an enriched lithospheric mantle source, with implications for long-lived mantle, widespread Neoproterozoic rifting, and Rodinia configuration.

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
S. S. Sun
- 01 Jan 1989
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.
