“…Therefore, mineral assemblages and estimated pressure–temperature from BIFs of Mahoba area represent the peak metamorphic event of lower granulite facies. This metamorphic event may be correlated to the ~3.2 Ga amphibolite facies metamorphic event reported from BIF rock of Mauranipur greenstone (Raza et al, 2022).…”

“…Further, the P-T derived using TWQ program is 745 C temperature with 5.6 kb pressures (Figure 6), further supporting a lower granulite facies condition of metamorphism of BIFs. Recent studies by Raza et al (2022) for similar garnetiferous BIFs from Muranipur area have given the P-T estimate with temperature varying between 450 and 500 C and pressure ranging between 0.1 and 0.2 GPa, indicating a lower amphibolite condition. Therefore, mineral assemblages and estimated pressure-temperature from BIFs of Mahoba area represent the peak metamorphic event of lower granulite facies.…”

“…Furthermore, Singh and Slabunov (2015a) and Slabunov and Singh (2019) reported geochemical data for a fewer number ( n = 8) of BIFs samples from two localities (Babina ( n = 5) and Manuranipur ( n = 3)) greenstone belts, but the discussion was mainly limited to the geodynamic aspects of this area. More recently, Raza et al (2022) presented in‐situ U–Th–Pb total monazite geochronology in BIFs from the Mauranipur, Bundelkhand Craton and highlighted their three metamorphic events at ~3.2, 2.5, and 2.1 Ga, respectively. However, the genesis and time of deposition of BIFs in the Budelkhand Craton, is still inadequate, particularly in the central part, due to the paucity of relatively large number of petrological, mineralogical, and geochemical data.…”

Handling Editor: C. Manikyamba Palaeo-Mesoarchean Banded Iron formations (BIFs) of central Bundelkhand greenstone belts occur from Babina (in the west) to Mahoba (in the east) via Mauranipur along with the E-W trending of the Bundelkhand Tectonic Zone (BTZ). In the present study, we report petrological, geochemical, and mineralogical data of BIFs from the Babina, Mauranipur, and Mahoba greenstone belts of central Bundelkhand Greenstone Complex to address their source characteristics and deposition environment. The lithological association of BIFs in the Babina and Mauranipur greenstone belts consists of pillowed basic-ultrabasic volcanics and metasediments, whereas in the Mahoba greenstone belt, BIFs and quartzite occur within basic volcanics. These lithological associations collectively suggest that the entire succession was deposited in a marine environment. Based on geological setting, they are classified as Algoma-type. The main mineral assemblages of the Babina and Mauranipur BIFs are composed of magnetite, quartz, ±garnet, hornblende, chlorite, and apatite, whereas the Mahoba BIFs along with magnetite and quartz, poised of two distinct mineral assemblages; the first one is Opx-Cpx-Grt and the other one is Grt-Hbl. The preliminary P-T study of these BIFs implies that they had gone through amphibolite-to granulite-facies metamorphism. The geochemical characteristics show that BIFs from the Babina and Mauranipur greenstone belts are dominated by higher quartz and magnetite (total content = 90.63-99.95 wt.%), whereas the Mahoba greenstone belt is characterized by lesser quartz and magnetite components (total content = 86.68-94.58 wt.%). The PAAS (Post Archean Average of Australian Sediments)-normalized REE patterns display significant positive Eu anomaly (Eu/Eu* up to 2.50) with well-represented negative Ce anomalies (Ce/Ce* = 0.27-1.20). The REE and trace element ratios of BIFs from the Babina and Mauranipur greenstone belts suggest that they were formed by high-T hydrothermal fluid activity without or very less continental input. Moreover, the Mahoba greenstone belt BIFs are formed by low-T hydrothermal fluid activity with substantial continental input. Their chemical variation suggests the shallowing of the proto-basin from the Babina in the west to Mahoba in the east. Tectonic discrimination plots imply the BIFs of the

The amphibolites from the Mauranipur and Babina regions are located in the central part of the Bundelkhand Craton (BuC), northern India. During the geodynamic evolution of the BuC, these amphibolites underwent medium-grade metamorphism. This study combines textural observations of amphibolites from two distinct regions (Mauranipur and Babina) with mineral chemistry and phase equilibrium modelling. Observations suggest that the amphibolites of both areas have gone through three stages of metamorphism. The pre-peak stage in the amphibolites from the Mauranipur and Babina regions is marked by the assemblages Ep-AmpCpx-Pl-Ilm-Ru-Qz and Ep-Amp-Cpx-Pl-Ab-Ilm-Qz respectively; the peak metamorphic stage is characterized by the mineral assemblages Amp-CpxPl-Ilm-Ru-Qz and Amp-Cpx-Pl-Ilm-Qz-H2O, which is formed during the burial process, and the post-peak stage is represented by the assemblages Amp-Pl-Ilm-Ru-Qz and Amp-Pl-Ilm-Qz-H2O respectively, which is formed by exhumation event. By applying the phase equilibria modelling in the NCFMASHTO system, the P-T conditions estimated from pre-peak, peak to post-peak stages are characterized as 6.7 kbar/510 ℃, 7.3 kbar/578 ºC and > 3.0 kbar/>585 ºC, respectively, for the Mauranipur amphibolites; and 6.27 kbar/520 ºC, 5.2 kbar/805 ºC and > 3.0 kbar/>640 ºC respectively for Babina amphibolites. The textural association and P-T conditions of both amphibolites suggest that these rocks were affected by burial metamorphism followed by an exhumation process during subduction tectonism in the BuC.
