“…The Aravalli orogen (1.7 to 0.96 Ga) and the Sausar orogen in Central India (ca. 2.1 to 0.9 Ga, Mohanty, 2021) were correlated with the Xiong'er belt of North China Craton (1.78 to 1.45 Ga) and Capricorn orogen in Australia in the reconstruction of Columbia Supercontinent (Zhao et al, 2002(Zhao et al, , 2009Mohanty, 2021;Banerjee et al, 2021). Hence, North China Craton is plotted outboard of the Columbia Supercontinent close to India.…”

“…Two major (Chhattisgarh and Indravati) and many small sedimentary basins (Khariar and Sabri) occur in the northern part of the Bastar Craton. These basins form a parallel zone to the eastern ghats and their evolution is regarded as the manifestation of the extension events of Bastar Craton (Mohanty, 2021 and references therein). During the extension of the Bastar Craton many mafic dykes were emplaced (Pisarevsky et al, 2013; Ratre et al, 2010; Srivastava & Gautam, 2009 and references therein) along NW–SE to N–S strike direction.…”

Origin and evolution of vanadium‐rich oxide and titanite phases in lamprophyre and mafic dykes from the Nuapada diamondiferous Lamproite field, BastarCraton‐EasternGhats Mobile belt contact, India: Metallogenic and geodynamic implications

Transitional boundaries of the craton and mobile belt mark diverse and long-term tectono-thermal events like hot and cold lithospheric contact, back-arc-type subduction, and also constitute a favourable locale for metallogeny. The exact nature and origin of such metallogenic enrichment in the lithospheric mantle source beneath contact zones are still uncertain. The contact of Bastar Craton and the Eastern Ghat Mobile Belt (EGMB), India, provides an ideal geological setup to study the metallogenic enrichment processes. In this study, we present a detailed petrographic and mineralogical investigation of various iron oxide phases and titanites in spatially and temporally distinct lamprophyre and mafic dykes from the diamondiferous Nuapada Lamproite Field (NLF) at the contact between Bastar Craton and EGMB. Diverse textural assemblages of oxides, namely, trellis, sandwich-type exsolutions and reaction-replacement, are widespread. Ilmenites, magnetites and titanites from the mafic dykes as well as lamprophyre exhibit an anomalous enrichment of vanadium (V 2 O 3 up to 3.7 wt%), whereas ilmenites are also characterized by their elevated manganese content (MnO up to 3.8 wt%). Mineral chemistry-based plots and thermo-oximetric studies suggest the magmatic origin of iron oxides belonging to the Fe-Ti-V-type ore in which partitioning and sequestration of the elements were controlled by differential crystallization, exsolution and fractionation rather than any imprints of contamination. Multiphase sequestration of vanadium as well as manganese in lamprophyre and mafic dykes, separated in space as well in relative depths of origin, signifies the presence of a fertile mantle. The role of subductionderived metasomatized fluids as a causative factor of vanadium metallogeny in this domain is evaluated. Low-Mg and high-Mn ilmenites of this study are consistent with the reported occurrences of diamonds from the NLF and adjoining areas of the Bastar Craton.

“…The Bastar Craton is composed mainly of five major tectonic belts: Sausar-Chilpi belt, Bengpal-Sukma belt, Sonakhan belt, Amgaon belt and Kotri-Dongargarh belt flanked the northern, southern, eastern, western and central part of the craton and three supracrustal sequences: Dongargarh suite, Sakoli suite and Sausar suite [24]. The oldest group among five belts is Bengpal and Sukma group [22][26] and the Chilpi group represents the youngest age [17] [18]. The gneissic complex is considered as the basement of the craton which essentially comprises tonalite-trondhjemite gneisses (TTG) and granites with paleo-archaean to neoarchaean in age [7][22] [27].…”

“…The Kotri-Dongargarh belt is the north-south trending tectonic belt located at the central part of Bastar Craton and consisting of various cycles of volcanism and sedimentation [6] [28]. The granitic plutons, intercalated volcanic and sedimentary sequences, and gneissic rocks are collectively considered as Dongargarh Supergroup located in the northwestern flank of the Bastar Craton [18]. The rocks of the Dongargarh Supergroup evolved in the Sitagota syncline [27] and the Amgaon group represented as the basement for the volcano-sedimentary sequence [19].…”

Composition of basalts in magmatic arcs influenced by the subducting lithosphere, mantle wedge, dehydration of oceanic crust, and/or crustal assimilation beneath the arc. In this paper, we compiled earlier published geochemical data of Dongargarh basalts to decipher the genesis of volcanic rocks. SiO2 vs (FeO + MgO) plot of basalt suggests the volcanic rocks are tholeiitic in composition. Primitive mantle and REE normalized plots indicate either the source was enriched mantle or a possible interaction of depleted magmatic source with the Paleoarchean continental crust in the Bastar Craton. The primitive mantle normalized diagram shows a negative anomaly of Nb, Ti, and Ta indicates subduction-related magmatism. In addition to the basalt composition, variation diagrams for tectonic settings represent the continental arc-related magmatism. From the available geochemical data of basalts and earlier studies on Dongargarh volcanic, there was an oceanic ridge that was subducted beneath the continental plate. The source of Pitepani basalts was significantly enriched in HFSE and REE as compared to mid-oceanic basalts. Thus the study finds the volcanic rocks are part of enriched mantle source that formed in the subduction-related magmatism.
