Analysis of 3.3 Ga tonalite–trondhjemite–granodiorite (TTG) series granitoids and greenstone belt assemblages from the Bundelkhand craton in central India reveal that it is a typical Archaean craton. At least two complexes can be recognized craton, namely (i) Central (Babina, Mauranipur belts) (ii) Southern (Girar, Madaura belts). The complex contains three tectonostratigraphic assemblages: (1) metamorphosed basic or metabasic, high-Mg rocks; (2) banded iron formations (BIFs); (3) felsic...

ABSTRACT The Shirokaya Salma eclogite‐bearing complex is located in the Archean–Palaeoproterozoic Belomorian Province (Russia). Its eclogites and eclogitic rocks show multiple clinopyroxene breakdown textures, characterized by quartz–amphibole, orthopyroxene plagioclase lamellae. Representative samples, a fresh eclogite, two partly retrograded eclogites, strongly rock, were collected for this study. Two distinct mineral assemblages—(1) omphacite+garnet+quartz+rutile±amphibole (2)...
The Mauranipur and Babina greenstone belts of the Bundelkhand Craton are formed Central complex (CBGC). This represents tectonic collage which has not been previously studied in depth. purpose this study is to contribute understanding main features Archaean crustal evolution Craton. CBGC consists two assemblages: (1) early assemblage, composed basic-ultramafic, rhyolitic–dacitic, banded iron formation units, (2) late a felsic volcanic unit. units assemblages tectonically unified with...
Giant quartz veins are widespread on the Bundelkhand Craton of Indian Shield which precise ages with a SHRIMP-II, U-Th-Pb isotope quantified in this article. Their relative geological age is well-documented: they cut Paleoproterozoic (2150–1800 Ma) sediments Bijawar Group and overlain by Proterozoic (1670–1030 at base Upper Vindhyan Supergroup. dating zircon grains from vein was carried out to assess major event their formation as 1866 ± 12 Ma. This data consistent veins. In addition, were...
This paper addresses the relationships between relic amphibole-eclogite facies (AE) eclogites and their host units, Archaean amphibolites, enveloped by tonalite–trondhjemite–granodiorite (TTG) gneisses, in Kuru-Vaara study area northern Belomorian Province. According to observational constraints, crystallization of peak omphacite + Mg-garnet ± kyanite assemblage subsequent replacement clinopyroxene–plagioclase symplectite occurred before earliest deformational, metamorphic, migmatization...
The present study reports trace elemental data from 39 Paleoarchean (3.43 and 3.25 Ga) zircons separated quartzite near Girar, which forms a part of the South Bundelkhand Supracrustal Complex in Central India. are prismatic, have well-developed oscillatory zoning their Th/U ratio ranging 0.27 to 8.62 is comparable that typical magmatic zircons. Crystallization temperature 620-776°C using titanium-in-zircon thermometer, positive slope zircon REE patterns, Ce anomalies along with mineral...

abstract Archaean supracrustal complexes, known in the Fennoscandian (Baltic) Shield, are described and discussed by analysing time sections 3.1-2.9, 2.9-2.75 2.75-2.65 Ga. Data on granitoid interrelated space, evidence for metamorphic events classified presented briefly. Fragments of ophiolitic eclogitic associations have been found rocks Shield. The first continental crust Shield is from Meso-Archaean (3.5-3.1 Ga); isolated microcontinents, such as Vodlozero, lisalmi North Finland,...
Abstract This study presents petrological and geochemical data on Neoarchean granitoids from the northern central parts of Bundelkhand Craton to discuss its crustal evolution tectonic history. The deals with two granitoid suites, i.e. tonalites–trondhjemites–granodiorites (TTG) sanukitoids. TTGs are characterized by high SiO 2 , Na O mostly low moderate Mg#. They display enrichment in light rare earth elements, moderately fractionated heavy elements (HREE) Sr/Y ratios, suggesting their...
