• The Sandmata Complex preserves Neoarchaean protolith ages of 2.68–2.42 Ga. • Zircon-monazite ages indicate peak granulite facies metamorphism at 1.90–1.78 Ga. • Sandmata quartzofeldspathic gneisses record an isobaric cooling P–T path. • The complex was tectonically active up to the Neoproterozoic (∼0.90–0.78 Ga). The Sandmata Complex in the Aravalli Craton of northwestern India experienced syn- to post-collisional high-grade metamorphism and migmatization related to the 1.9–1.7 Ga Aravalli orogeny. Garnet-bearing quartzofeldspathic gneisses are an important rock type in the Sandmata Complex. Their prograde assemblage is represented by garnet cores and inclusion minerals Bt + Pl + Qz, whereas the assemblage Pl + Kfs + Qz + Bt matrix + Sil + Ilm, along with chemically homogeneous garnet porphyroblasts, represents peak metamorphism. Post-peak retrograde metamorphism is reflected in the growth of muscovite, chlorite and biotite, and diffusion adjustments in garnet rims. Mineral paragenesis, mineral chemistry, conventional thermobarometry, and phase equilibrium modelling indicate P–T conditions of 6.7–10.2 kbar at 725–830 °C for peak metamorphism, and 4.8–6.9 kbar at 450–610 °C for post-peak retrogression. The P–T conditions determined from the quartzofeldspathic gneisses define a near-isobaric cooling P–T path. In contrast, previously studied high-grade pelitic gneisses and metagranitoids from the Sandmata Complex define an isothermal decompression P–T path. U–Pb dating of magmatic zircon cores in the quartzofeldspathic gneisses provides the crystallization age of their felsic protoliths as ∼ 2.52 Ga. Zircon and monazite geochronology show that peak metamorphism occurred at ∼ 1.90–1.78 Ga and thus shortly preceded the emplacement of the Gyangarh-Asind igneous suite and Anjana granite, previously dated at ∼ 1.72–1.64 Ga. A model of oceanic crust subduction followed by continent–continent collision during the Aravalli orogeny can explain granulite facies metamorphism in the Sandmata Complex. The combined results of this and previous studies support the operation of modern-style plate tectonic processes involving subduction and continental collision during Palaeoproterozoic time. We also identify a younger (∼0.90–0.78 Ga) metamorphic episode, preserved mostly in recrystallized monazite grains elongated parallel to the final deformation fabric, likely related to the South Delhi orogeny.

Interpreting the origin of U Pb discordance in zircons in intrusives that experience high -T metamorphic-deformation events is challenging. We investigate in depth the origin of U Pb dates obtained from garnet-bearing border zone granitoids and a sheared ferrodiorite dyke bordering the Balangir anorthosite pluton, eastern India. The crustal domain is known for discordant ages resulting in disputes regarding the age of intrusion and multiple granulite facies events. We shed light on the origin of the discordant dates utilizing CL imaging, electron backscatter diffraction analysis, trace element mapping in zircons, and Ti-in-zircon thermometry. Zircons in the foliated border zone granitoids (BZG) comprise (a) embayed cores with varying Y, U and Hf oscillatory zones, and (b) well-faceted chemically-homogeneous mantles crystallographically continuous with the cores, which truncate the oscillatory zones. In the intensely sheared ferrodiorite, cauliflower-shaped zircons possess profuse micropores and micro-fractures. Ti-in-zircon temperatures (700–950 °C) overlap in the texturally-distinct zircons, but are somewhat lower in the mantles/cauliflower-shaped zircons relative to the oscillatory-zoned cores in BZGs. LA-ICP-MS dates of zircons in four samples constitute a near-unique discordia line with the upper and lower intercepts at ca. 980 Ma and 495 Ma. Interestingly, dates from the mantles are highly variable with no correlation between age decrease and distance to the cores. The lack of concordant dates at the two intercepts, and the increase in discordance away from the intercepts preclude episodic zircon growth, and suggests a single-stage granulite facies event (ca. 495 Ma) that modified the ∼980 Ma zircon xenocrysts entrained from protoliths into the intrusives. We propose the age discordance was caused by melt-mediated high-T interface coupled dissolution-precipitation processes at ∼495 Ma. Variable inheritance of isotopic signatures of ∼980 Ma zircon xenocrysts in the younger zircons contributed to discordance in U Pb systematics; the effect of variable inheritance of ∼980 Ma isotope signatures is less pronounced in the cauliflower-shaped zircons from the HFSE enriched ferrodiorite residual melts from high degree of plagioclase fractionation. Our results are consistent with a distinct Cambrian (∼495 Ma) orogeny involving emplacement of anorthosite pluton and related intrusives and high- T granulite-facies deformation-metamorphism in the ∼980 Ma Eastern Ghats Province, and are a direct record of Cambrian collision between the Eastern Ghats Province and the Archean cratonic nucleus. • Complex chemical zoning and structures in zircons in high-T granitoid-ferrodiorite. • Identical U Pb discordia in multiple samples; intercepts at ∼980 Ma and ∼ 495 Ma. • 980 Ma: age of oscillatory zoned in Y, Hf, U zircon xenocrysts in 495 Ma intrusive. • 495 Ma: melt-mediated xenocryst embayment, zone truncation, epitaxial mantle growth. • Melt-mediated variable isotope inheritance led to discordant dates.

• Presented P–T evolution and monazite geochronology of Bhopalpatnam Granulite Belt. • Hitherto unreported HP-HT metamorphism and clockwise P–T history for quartzofeldspathic gneiss and mafic granulites. • Timing of HP-HT and MP-HT granulite-facies metamorphism at 2588–2461 Ma and 2499–2308 Ma, respectively. • Bhopalpatnam and Karimnagar granulite belts evolved coherently until 1.6–1.4 Ga. The Bhopalpatnam Granulite Belt (BGB), located within the southwestern part of the Bastar Craton (India), is composed of granite gneisses with numerous enclaves of high-grade rocks, including quartzofeldspathic gneisses, orthopyroxene-free mafic granulite, and garnetiferous two-pyroxene granulite. In addition, the marginal parts of the belt preserve patches of garnetiferous psammo-pelitic gneisses. New petrographic, metamorphic (conventional and phase equilibria modelling) and monazite geochronological investigations of these high-grade rocks constrain the conditions and timing of granulite-facies metamorphism and enable to demonstrate the tectonometamorphic history of the BGB. The garnet-bearing psammo-pelitic gneisses underwent medium pressure-high temperature (MP-HT) and retrograde metamorphism at P-T conditions of 9.4 ± 1.0 kbar/797 ± 39 °C and 5.1 ± 1.1 kbar/697 ± 69 °C, respectively. The quartzofeldspathic gneisses experienced high pressure-high temperature metamorphism (HP-HT; 12.0 ± 0.9 kbar/785 ± 48 °C), followed by retrogressive cooling at 10.6 ± 0.8 kbar/683 ± 42 °C. The orthopyroxene-free mafic granulites and two-pyroxene granulites witnessed HP-HT metamorphism at 11.0 ± 0.8 kbar/827 ± 45 °C, followed by MP-HT metamorphism at 8.4 ± 0.9 kbar/803 ± 66 °C and retrograde cooling at 5.7 ± 1.5 kbar/555 ± 80 °C. The U–Th–total Pb dating of monazites from the quartzofeldspathic gneiss yielded peak (HP-HT) metamorphic age at 2588–2461 Ma, MP-HT metamorphism at 2499–2308 Ma, and thermal events associated with granite magmatism at 2292–2111 Ma. Based on similar clockwise P–T history and Late Archean-Early Mesoproterozoic tectonothermal events, we suggest that the Bhopalpatnam and Karimnagar granulite belts evolved coherently until the Mesoproterozoic time and eventually rifted apart during the development of the Pranhita-Godavari rift basin between ∼ 1.6–1.4 Ga. The HP-HT and MP-HT granulite-facies metamorphic episodes identified in the BGB are correlated with the continent–continent collision between Bastar and eastern Dharwar cratons.

The Banded Gneissic Complex of the Aravalli Craton of northwestern India comprises Palaeo‐ to Neoarchaean (3.3–2.7 Ga) gneisses, including tonalite–trondhjemite–granodiorite (TTG) gneisses, intruded by Neoarchaean (2.6–2.5 Ga) TTGs, sanukitoids, and potassic granites. The latter include the Malola granite that crops out near Bhilwara and forms the basement for the Mesoproterozoic Pur‐Banera mineralized belt. The granite has experienced three deformation events, represented by an S1 foliation and superimposed open folds and dextral shears. Textural evidence and thermobarometry indicate that prograde metamorphism initially forming actinolite and subsequently diopside, and culminating in the upper amphibolite facies, was followed by retrograde metamorphism in the greenschist facies with fluid influx, forming zoisite. Zircon geochronology yields a crystallization age of 2,538 ± 11 Ma and indicates a prominent metamorphic overprint in the region at 1,307 ± 9 Ma. The Malola granite has low Sr–Nd isotopic ratios, enrichments in fluid‐mobile elements (Cs, Rb, Ba, Th, and Pb), and depletions in alteration‐resistant elements (Nb, Ta, and Ti). These characteristics combined with mineralogical evidence suggest that the granite was derived by anatexis of older crystalline crust (possibly granulitic lower crust) in the same subduction zone setting inferred previously for other Neoarchean granitoids in this region. Geochemical and Sr–Nd–Hf isotopic similarities between the Malola granite and Neoarchaean granitoids of the Aravalli, Bundelkhand, Bastar, Dharwar, and Congo cratons indicate a major role for anatectic crustal reworking in their genesis.
