“…Also, the biogenic affinity of the various microfossils, their biostratigraphic significance and different aspects of life cycle are not well understood. Sathyanarayan et al (1987) reported that the dolomites and limestones of the Bagalkot Group have d 13 C values of 0.3 + 1.2‰ (V-PDB), reflecting 'normal' marine carbonate facies. In contrast, the dolomites of the younger Badami Group exhibit markedly increased average d 13 C values of 3.4 + 0.5‰ (V-PDB) suggesting a primary hypersaline environment.…”

The Proterozoic Kaladgi-Badami and Bhima basins are intracratonic basins occurring over the Archaean Dharwar craton. The Kaladgi-Badami Basin contains arenites, shales and carbonates with minor cherts and conglomerates deposited in continental, transitional and shallow-marine environments presumably during the late Palaeoproterozoic/Mesoproterozoic to Neoproterozoic. The lower part of the succession (Bagalkot Group) is deformed into east-west-trending elongated doubly plunging synclines and anticlines. The upper part of the succession (Badami Group) is undeformed and unconformably overlies the lower part. The evolution of the Kaladgi-Badami Basin was controlled by movements along east-west-trending normal faults under an extensional stress regime. The Bhima Basin hosts mainly limestones with subordinate arenites and shales deposited in fluvial, deltaic and tidal flat environments possibly during the Neoproterozoic. These sediments are undeformed except along faults with significant strike-slip components. The basin is exposed in narrow strips arranged in an en echelon pattern and appears to be a pull-apart basin. Inadequate data exist on the age of the basin fills, the deep basinal architecture, subsidence history and tectonic controls for both of the basins. Future research may be directed towards these aspects which will have wide implications for understanding intracratonic basin formation, reconstructing Proterozoic supercontinents and studying the evolution of the atmosphere and primitive life forms.

“…Figure 5 shows (Pierson 1981), and consequently Sr is expelled from the crystal during dolomitization. Sr values fall significantly with increasing Mg content (Sathyanarayan et al 1987;Carpenter et al 1991) and suggest that rapid precipitation of dolomitic phases may partition strongly against Sr ions. Enriched Mn/Sr ratios may therefore result, in part, from the early diagenetic dolomitization of the Society Cliffs Formation.…”

“…Where available, age constraints for these units suggest deposition prior to -1300 Ma (age constraints are from the following sources: Bangemall Formation (Gee et al 1976; D.R. Nelson, quoted in Buick et al 1995); Billyakh Group ; Carswell Formation (Bell 1981;Ramaekers 1981;Clauer et al 1985); Changcheng, Jixian, and Luonan groups (cited in Xiao et al 1997); Belt Supergroup (Zartman et al 1982;Aleinikoff et al 1996;Anderson and Davis 1995, and references therein) (Beeunas and Knauth 1985); the Turukhansk Group, Siberia ; the Raipur (Schidlowski et al 1975;Murti and Aswathanarayana 1982), Kurnool (Schidlowski et al 1975;Dasari 1989), and Badami and Bhima (Sathyanarayan et al 1987) groups, India; and the Neoproterozoic Atar Group, Mauritania (Fairchild et al 1990) and Callana Dolomite, Australia (Lambert 1984). Of these units, the Bylot Supergroup (Heaman et al 1990;LeCheminant and Heaman 1991), Hunting Formation (Jones and Fahrig 1978), Narssârssuk Formation (Dawes 1997), Allamoore Formation (Roths 1993), Grenville Supergroup (Heaman et al 1986;van Breemen and Davidson 1988), Mescal Limestone (Livingston and Damon 1968;Silver 1978;Heaman and Grotzinger 1992), Turukhansk Group (Ovchinnikova et al 1995), and Callana Dolomite (Fanning et al 1986) contain evidence supporting deposition between -1300 and -800 Ma.…”

Abstract:The Bylot Supergroup, northern Baffin Island, contains >1500 m of platform, shelf, and slope carbonates deposited between -1270 and -723 Ma. Limited chronostratigraphic data have led to the broad correlation of the Bylot Supergroup with predominantly Neoproterozoic successions in northern and western Laurentia; yet, detailed correlation has been impossible given biostratigraphic and lithostratigraphic limitations. Carbon-isotope chemostratigraphy represents a potential dataset to constrain such interregional correlations. Carbon isotopic data from the Bylot Supergroup and broadly coeval successions from Somerset Island and northwest Greenland reveal distinct stratigraphic trends in δ 13 C, with intervals of moderate 13 C enrichment (+3.5 ± 1‰) punctuated by excursions to slightly negative values (-1.0 ± 1‰). Although the scale of the observed variation is muted relative to Neoproterozoic standards, the dissimilarity of values to those recorded in northwestern Laurentia suggests that these strata delineate a discrete depositional interval. Comparison of isotopic values with published data indicates that δ 13 C values between approximately -1.0 and +4.0‰ are characteristic of the interval between -1300 and -800 Ma. This pattern is distinct from that of younger Neoproterozoic successions, which typically record values >+5‰, and older Mesoproterozoic successions, which record values near 0‰, and suggests that these moderately positive values may be useful for broad time correlation. Compilation of new and published data permits the tentative reconstruction of a global Mesoproterozoic carbon isotopic curve.Résumé : Le Supergroupe de Bylot, dans le nord de l'île de Baffin, est formé de >1500 m de carbonates qui furent déposés sur une plate-forme continentale et un talus, entre -1270 et -723 Ma. Les données chronostratigraphiques limitées n'autorisent qu'une corrélation d'ordre général entre le Supergroupe de Bylot et les successions principalement néoprotérozoïques des régions septentrionales et occidentales de Laurentia; jusqu'à présent, il a été impossible d'établir une corrélation détaillée en raison du petit nombre de données biostratigraphiques et lithostratigraphiques. La chimiostratigraphie des isotopes du C a fourni un ensemble de données pouvant aider à mieux définir les corrélations inter-régionales. Les résultats des analyses d'isotopes du C pour le Supergroupe de Bylot et les successions grossièrement contemporaines de l'île Somerset et du nord-ouest du Groenland révèlent des tendances stratigraphiques distinctes dans les valeurs de δ 13 C, avec des intervalles d'enrichissement modéré de 13 C (+3,5 ± 1‰), ponctués d'incursions de valeurs légèrement négatives (-1,0 ± 1‰). Même si l'échelle de la variation observée est atténuée par rapport aux standards du Néoprotérozoïque, les valeurs différentes de celles enregistrées dans le nord-ouest de Laurentia suggèrent que ces strates représentent un intervalle de sédimentation discontinue. La comparaison des données isotopiques avec celles déjà publiées in...

In contrast, the dolomites of the younger Badami and Bhima Groups exhibit markedly increased average d 13 C values of 3.4 ± 0.5‰ [PDB] suggesting a primary hypersaline (evaporitic) environment.…”

“…Petrographic studies and major and trace element (including REE) geochemical data on quartz arenites, arkoses and shales of the Rabanpalli Formation indicate that the clastics were deposited in an oxic environment and derived principally from the granitoids of the Dharwar craton (Nagarajan et al, 2007a,b). Sathyanarayan et al (1987) interpreted primary hypersaline (evaporitic) environment from the d 13 C values of Bhima carbonates. Kale and Peshwa (1989) put forward pull-apart model for the formation of the basin triggered by NW-SE shear couple.…”
