“…For the present study, we collected a total of 15 BIFs samples that are representative of the Mauranipur and Mahoba greenstone belts. In addition, literature data for nine samples from the Babina greenstone belt (Alfimova et al, 2019; Singh & Slabunov, 2015a, Singh & Slabunov, 2015b; Table 2) and two samples from the Mauranipur (Alfimova et al, 2019: Table 2) were compiled.…”

“…Malviya, Arima, and Pati., J.K. (2013) argued that BIFs in the Bundelkhand Craton are of Archean affinity and are associated with or without amphibolites. Recently, based on Nd isotope data, Alfimova et al (2019) have discriminated the Bundelkhand BIFs and suggested them to be Algoma type in origin. 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.…”

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 central Bundelkhand complex consists of various lithologies, like, high magnesian pillow basalt, basaltic komatiite, volcaniclastic metasediments, serpentinised ultramafic rocks, banded iron formation (BIF) with local interlayer of chert and felsic volcanics (dacite and rhyolite) along with garnet chlorite schists, amphibolites, chlorite-actinolite-talc bearing ultramafic schists, and corundum-bearing white schists. On the other hand, southern Bundelkhand complex is dominated by quartzite, BIF, chlorite schist, and marble (Malvia et al, 2006;Singh and Slabunov, 2016;Slabunov et al, 2017a;Slabunov and Singh 2018;Alfimova et al, 2019). Distinct episodes of TTGs formation viz.…”

Characterization of multiple episodes of melt generation from lower crust during Archaean using amphibole composition

Spatial association of tonalite trondhjemite granodiorites (TTGs) and high-K granitoids (anatectic and hybrid granites) from the Bundelkhand Craton (BC), Central India, is well known. Geochronological data indicates multiple episodes of formation of these high silica rocks showing a spread of ~1 Ga during Paleo to Neoarchaean. In the present study, we try to understand the evolution of TTGs and high-K granitoids (hybrid granites) from the BC using amphibole composition. The amphibole in both TTGs and high-K granitoids (hybrid granites) from the BC are characterised as magmatic, zoned, and calcic in nature. We find that the amphibole composition of the studied rocks is dominated by magnesiohornblende along with less common occurrence of tschermakite, magnesiohastingsite and edenite. Overall variation in amphibole compositions in terms of exchange vectors show a well defined linear trend (except for a late stage low-grade metamorphic readjustment), which suggests melt control over crystallization and evolution of amphibole chemistry. Moreover, the geothermobarometric analysis points towards higher pressure formation of TTGs in comparison to that of high-K granitoids (hybrid granites), with nearly the same temperature conditions in both the cases. Combining all our findings, we propose the evolution of the two considered rock types through lower crustal melting under varying P H2O conditions at different depths of emplacement.

“…Also, in the southern part of BuC, it encompasses tectonic contact with TTGs . Recently Alfimova et al (2019) reported the first geochemical and Sm-Nd isotopic data of iron-rich and silica bands from BIFs of BuC and compared them with those from Fennoscandian shield (FS) and East-European Platform (EEP). They compared Algoma type BIFs of BuC and FS with EEP and they observed that εNd [t] for silica-rich layers is elevated compared to ironrich layers for all the samples.…”
