“…The studied terrane forms a narrow, linear WNW-ESE trending zone which occurs in between the Singhbhum Craton in the north and the Proterozoic Eastern Ghats Belt in the south (Crowe et al, 2003;Misra and Gupta, 2014;Ghosh et al 2016). This terrane is variably named as the 'Rengali Assemblage' (Mahalik, 1994), 'Rengali Domain' (Nash et al, 1996) or 'Rengali Province' (Crowe et al, 2001;Dobmeier and Raith, 2003).…”

“…1a) records a remarkable Archean growth history (Saha, 1994). Its southern margin is composed of high-grade granulites along with mediumgrade metasedimentary and metavolcanic rocks, collectively termed as the Rengali Province (Crowe et al, 2001(Crowe et al, , 2003Dobmeier and Raith, 2003) that separate the PaleoeMesoarchean granitegreenstone terrane of the SC (e.g., Saha, 1994;Mukhopadhyay et al, 2012) from the essentially high-grade PaleoeMesoproterozoic Eastern Ghats Mobile Belt (EGMB) Das et al, 2011;Korhonen et al, 2011;Gupta, 2012;Dasgupta et al, 2013 and references therein). Although the Rengali Province constitutes a part of the EGMB, its rock types, metamorphic style and isotopic signatures are different from the major part of the EGMB, known as the Eastern Ghats Province or EGP (Dobmeier and Raith, 2003).…”

a b s t r a c tThe southern boundary of the Singhbhum Craton witnessed multiple orogenies that juxtaposed thin slice of granulite suite of the Rengali Province against the low-grade granite-greenstone belt of the craton along the EeW trending Sukinda Thrust. The strong southerly dipping mylonitic foliation within the granulites along with the prominent down-dip mineral lineation, suggest a northerly-verging thrusting. Mylonitized charnockite at the contact zone contains enclaves of mafic and ultramafic granulite, whereas granitoid gneiss contains enclaves of pelitic granulite. Mafic granulite enclaves preserve an early (S 1M ) foliation that formed during D 1M deformation. This rock, along with the host charnockite, were intensely deformed by the D 2M thrusting event and resulting S 2M foliation development in both rock suites. Geothermobarometric and pseudosection analyses show that the garnet-clinopyroxene-plagioclaseorthopyroxene-ilmenite-quartz assemblage in mafic granulite was stabilized at high-pressure and temperature conditions (10À12 kbar, 860 C) and was overprinted by a fine-grained assemblage of clinopyroxene-plagioclase AE hornblende that developed during decompression (down to 5.5e7.5 kbar). Matrix hornblende shows incipient breakdown to garnet-clinopyroxene-quartz intergrowth due to a granulite facies reworking. A contrasting P-T history is preserved in the pelitic granulite. The peak assemblage garnet-orthopyroxene-cordierite-quartz-rutile was stabilized at w6.0 kbar, 730 C which resulted from heating of the mid crust magma during the D 2M thrusting. The contrasting P-T histories could result from the tectonic juxtaposition of lower-and mid-crustal section during the D 2M event. Evidences of an early orogenic imprint within the mafic granulite imply involvement of deep continental crust during southward growth of the Singhbhum Craton.Ó 2014, China University of Geosciences (Beijing) and Peking University.

Archaean granulite facies metamorphism at the Singhbhum Craton–Eastern Ghats Mobile Belt interface: implication for the Ur supercontinent assembly

In this study, we investigate the geological significance and the antiquity of lower crustal granulite facies metamorphism from the Rengali Domain, which lies in between the Singhbhum Craton in the north and the Eastern Ghats Mobile Belt in the south. Petrographic, mineral compositional, metamorphic reaction history and geothermobarometric studies of two representative metapelite granulite samples reveal widespread biotite melting at peak granulite facies metamorphic conditions of 7.8 ± 0.13 kbar, 849 ± 31°C and subsequent melt extraction, producing a mixture of residual granulites and melts in the Rengali Province. Depending on local bulk rock compositional variations, biotite melting produced peak metamorphic assemblages of garnet + cordierite in the more aluminous compositional domain, while garnet + orthopyroxene + cordierite resulted in domains of intermediate alumina. During post-peak cooling, there were localized developments of biotite + sillimanite + quartz symplectites replacing garnet and cordierite and biotite + quartz intergrowths after orthopyroxene. Application of garnet-orthopyroxene and garnet-biotite Fe-Mg exchange thermometers to co-existing garnet rim and symplectitic biotite show the extent of cooling to 610-660°C. Electron microprobe geochronology of texturally well constrained monazites indicates the timing of peak granulite metamorphism at 3057 ± 17 Ma and its metamorphic reheating at 2781 ± 16 Ma. The present findings when collated with available geological and geophysical data appear to indicate that the studied granulites and the associated granite gneisses, charnockite and enderbite suite of rocks of the Rengali Domain are part of the exhumed lower continental crust of the Singhbhum Craton. The significance of this Neoarchaean orogenesis in the 'Ur' supercontinent assembly is discussed.
