“…Malone et al (2008) noted that the youngest population of zircons from the Upper Bhander is older than 1000 Ma. This observation, coupled with the similarity in paleomagnetic directions from the Upper Vindhyan and the 1073.5 ± 13.7 Ma age of the Majhgawan kimberlite (Gregory et al, 2006), it is concluded that the Upper Vindhyan sedimentation was completed by ∼1000 Ma, a result consistent with recent geochronologic data from the Chhattisgarh basin to the south (Patranabis- Basu et al, 2008). The paleomagnetic data from the Bhander and Rewa Groups of the Upper Vindhyan sequence yield pole positions that overlap with the Majhgawan kimberlitic pole (Gregory et al, 2006).…”

“…Age constraints are generally lacking in most of these basins; however, Chakraborty (2006) tentatively called all of these basins 'classic examples of Proterozoic intracontinental basins' within India and remarked on similarity in their lithologies, depositional environments and stratigraphic architecture. Recent work in both the Vindhyan and Chhattisgarh basins (the results come from these basins only) supports Meso-Paleoproterozoic ages for these basins (Malone et al, 2008;Patranabis-Deb et al, 2008;Basu et al, 2008;Das et al, 2009).…”

“…The downward revision of age into the Mesoproterozoic proposed here for the Bhima and Kurnool (Palnad) basins is in tune with similar proposals made in recent years (e.g., Patranabis-Deb et al 2007;Malone et al 2008;Basu et al 2008;Das et al 2009) for the Chattisgarh and Upper Vindhyan sediments in Central India, which are generally considered to be homotaxial with the Bhima/Kurnool (Palnad) basins, based primarily on lithostratigraphic correlations (e.g., Naqvi 2005).…”

Carbonate xenoliths hosted by the Mesoproterozoic Siddanpalli Kimberlite Cluster (Eastern Dharwar craton): implications for the geodynamic evolution of southern India and its diamond and uranium metallogenesis

A number of limestone and metasomatised carbonate xenoliths occur in the 1,090 Ma Siddanpalli kimberlite cluster, Raichur kimberlite Field, Eastern Dharwar craton, southern India. These xenoliths are inferred to have been derived from the carbonate horizons of the Kurnool (Palnad) and Bhima Proterozoic basins and provide evidence for a connection between these basins in the geological past. A revised Mesoproterozoic age is proposed for the Bhima and Kurnool (Palnad) basins based on this kimberlite association and is in agreement with similar proposals made recently for the Chattisgarh and Upper Vindhyan sediments in Central India. The observed Bhima-Kurnool interbasinal uplift may have been caused by: (1) extension-or plume-related mafic alkaline magmatism that included the emplacement of the southern Indian kimberlites at *1.1 Ga, (2) mantle plume-related doming of the peninsular India during the Cretaceous, or (3) Quaternary differential uplift in this region. It is not possible, with the currently available geological information to constrain the exact timing of this uplift. The deep erosion of primary diamond sources in the Raichur kimberlite Field in the upper reaches of the Krishna River caused by this uplift could be the elusive source of the alluvial diamonds of the Krishna valley. Mesoproterozoic sedimentary basins can host world class unconformity-type uranium deposits. In light of its inferred Mesoproterozoic age, a more detailed stratigraphic and metallogenic analysis of the Kurnool basin is suggested for uranium exploration.

“…Recent paleomagnetic study combined with detrital zircon geochronology (Malone et al 2008) has painted an altogether different picture by suggesting 1000-1070 Ma age range for the Upper Vindhyans which contradicts all previous estimates and assumptions. Assuming this age estimate to be correct, the Upper Vindhyan succession becomes time contemporaneous to the sedimentary sequence of the Raipur Group in Chattisgarh basin of central India (Basu et al 2008).…”

Modal analysis and geochemistry of two sandstones of the Bhander Group (Late Neoproterozoic) in parts of the Central Indian Vindhyan basin and their bearing on the provenance and tectonics

The Neoproterozoic Bhander Group in the Son Valley, central India conformably overlying the Rewa Group, is the uppermost subdivision of the Vindhyan Supergroup dominantly composed of arenites, carbonates and shales. In Maihar-Nagod area, a thick pile of unmetamorphosed clastic sedimentary rocks of Bhander Group is exposed, which provides a unique opportunity to study Neoproterozoic basin development through provenance and tectonic interpretations. The provenance discrimination and tectonic setting interpretations are based on modal analysis and whole rock geochemistry. The average framework composition of the detrital sediments composed of quartz and sedimentary lithic fragments are classified as quartz arenite to sublitharenite. The sandstone geochemically reflects high SiO 2 , moderate Al 2 O 3 and low CaO and Na 2 O type arenite. The high concentration of HFSE such as Zr, Hf, and Th/Sc, Th/U ratios in these sandstones indicate a mixed provenance. The chondrite normalized REE pattern shows moderate to strong negative Eu anomaly which suggests that major part of the sediments were derived from the granitic source area. The sandstone tectonic discrimination diagrams and various geochemical plots suggest that the provenance of the lower and upper Bhander sandstone formations was continental interior to recycled orogen.
