“…The 1600 Ma event marks the fragmentation of the craton and the development of the P-G valley (Chaudhuri et al 2012). The ∼1600 Ma event was also identified in detrital zircon populations from the Sullavai Group of the P-G rift (Joy et al 2015). We note that Basu and Bickford (2015) consider the glauconite ages reported from the Somanpalli Group and Pandikunta Limestone to be unreliable (cf., Conrad et al 2011).…”

“…Previous geological mapping combined with recent geochronological studies conducted on the Purana basin rocks suggest that deposition in these basins started as early as 1.9 Ga (Cuddapah basin) and basin evolution possibly ended at <1.0 Ga (Rasmussen et al 2002;Ray et al 2002;Patranabis-Deb et al 2007;Malone et al 2008;Das et al 2009;Conrad et al 2011;Sheppard et al 2017). The Sullavai sedimentation continued until about 720 Ma or beyond in the P-G valley (Joy et al 2015). However, the exact ages of the youngest sedimentary sequences in each of the basins are only poorly constrained.…”

“…These erosional remnants are referred collectively in Indian literature as the 'Purana basins' (Holland 1907). Despite generally similar sedimentological features and lithofacies, as well as a similar time span of deposition between 2.0 and 0.7 Ga, the origin and evolution of these basins are not unanimously accepted (e.g., Basu and Bickford 2015;Joy et al 2015;Saha et al 2016). Recently, Basu and Bickford (2015) divided the Indian continent into three main cratonic domains (southern Indian, northern Indian, and western Indian blocks -SIB, NIB and WIB, respectively; figure 1) to more readily compare the evolution of the Purana basins within the context of supercontinent development and the tectonic evolution of the Indian Proterozoic mobile belts, including the Eastern Ghats mobile belt (EGMB), the Central Indian Tectonic Zone (CITZ), and the Aravalli-Delhi fold belt (ADFB).…”

The northern part of the Nellore-Khammam schist belt and the Karimnagar granulite belt, which are juxtaposed at high angle to each other have unique U-Pb zircon age records suggesting distinctive tectonothermal histories. Plate accretion and rifting in the eastern part of the Dharwar craton and between the Dharwar and Bastar craton indicate multiple and complex events from 2600 to 500 Ma. The Khammam schist belt, the Dharwar and the Bastar craton were joined together by the end of the Archaean. The Khammam schist belt had experienced additional tectonic events at ∼1900 and ∼1600 Ma. The Dharwar and Bastar cratons separated during development of the Pranhita-Godavari (P-G) valley basin at ∼1600 Ma, potentially linked to the breakup of the Columbia supercontinent and were reassembled during the Mesoproterozoic at about 1000 Ma. This amalgamation process in southern India could be associated with the formation of the Rodinia supercontinent. The Khammam schist belt and the Eastern Ghats mobile belt also show evidence for accretionary processes at around 500 Ma, which is interpreted as a record of Pan-African collisions during the Gondwana assembly. From then on, southern India, as is known today, formed an integral part of the Indian continent.

“…The question of the upper age limit of Purana successions and the possibility of their continuity into the late Neoproterozoic or even into the Cambrian have been debated for a long time (Saha et al, and references therein). Recently, U–Pb zircon ages from tuffs sampled from the Chhattisgarh and Indravati basins have led to a new hypothesis suggesting that closure of major cycle of sedimentation of at least these basins is at ~ 1,000 Ma (Bickford, Basu, Patranabis‐Deb, Dhang, & Schieber, ; Mukherjee, Bickford, Hietpas, Schieber, & Basu, ) and at ~ 700 Ma for the PG Valley Basin (Joy, Jelsma, Tappe, & Armstrong, ).…”

Depositional history and provenance of cratonic “Purana” basins in southern India: A multipronged geochronology approach to the Proterozoic Kaladgi and Bhima basins

Peninsular India is a collage of Archaean cratonic domains separated by Proterozoic mobile belts. A number of cratonic basins, known as “Purana basins” in the Indian literature, formed in different parts of the Indian Peninsula during extensional tectonic events, from Paleoproterozoic through Neoproterozoic times. In this contribution, we present a diversity of new geochronological data for different units within the Kaladgi and the Bhima basins, which overlie the western and eastern Dharwar cratons, respectively. The new geochronology data are discussed in terms of depositional history and provenance of these poorly understood Proterozoic intracratonic basins. For the Kaladgi Group, a U–Pb baddeleyite age of 1,861 ± 4 Ma obtained for a dolerite dyke intruding the Yendigere Formation is used to constrain the minimum age of deposition of the lower Kaladgi Group. This result demonstrates that this part of the succession is comparable in age to the Papaghni Group of the Cuddapah Basin, heralding onset of Purana sedimentation at ~1,900 Ma. The detrital zircon populations from the clastic rocks of the Kaladgi and Bhima basins show unique and distinct age patterns indicating different source of sediments for these two basins. Palaeocurrent analysis indicates a change in provenance from south or southeast to west or northwest between the Kaladgi and Bhima clastic sedimentation. New U–Th–Pb and Rb–Sr radiometric dates of limestones and glauconite‐bearing sandstones of the Bhima Group (Bhima Basin) and the Badami Group (Kaladgi Basin) indicate deposition at around 800–900 Ma, suggesting contemporaneity for the two successions. Thus, the unconformity between the Kaladgi Group and the overlying Badami Group represents a time gap of up to 1,000 Myr. These new results demonstrate the complex multistage burial and unroofing history of the Archaean Dharwar Craton throughout the Proterozoic, with important implications for exploration of metal deposits and diamonds in Peninsular India.

“…The Nallamalai Group consists of the lower Bairenkonda (Nagari) Formation, which is sandstone dominated and the upper Cumbum (Pullampeta) Formation consisting mainly of shales punctuated by sandstones and dolomites. The basal part of the Bairenkonda Formation was deposited between 1659 and 1590 Ma (Joy et al 2015). The youngest age limit of the Nallamalai Group was constrained to be as ∼1400 Ma old, which is in the form of Chelima lamproite (intrusion in to the Cumbum Formation; Rao et al 1996Rao et al , 1999Rao et al , 2012Kumar et al 2001).…”

Geochemical characterization of the siliciclastic rocks of Chitravati Group, Cuddapah Supergroup: Implications for provenance and depositional environment

Petrological and geochemical studies have been carried out on Pulivendla and Gandikota Quartzite from Chitravati Group of Cuddapah Supergroup to decipher the provenance and depositional environment. Both the units are texturally mature with sub-rounded to well-rounded and moderately to well-sorted grains. Majority of the framework grains are quartz, in the form of monocrystalline quartz, followed by feldspars (K-feldspar and plagioclase), mica, rock fragments, heavy minerals, with minor proportion of the matrix and cement. Based on major element geochemical classification diagram, Pulivendla Quartzite is considered as quartz-arenite and arkose to sub-arkose, whereas Gandikota Quartzite falls in the field of lith-arenite and arkose to sub-arkose. Weathering indices like CIA, PIA, CIW, ICV, Th/U ratio and A-CN-K ternary diagram suggest moderate to intense chemical weathering of the source rocks of these quartzites. Whole rock geochemistry of quartzites indicate that they are primarily from the first-cycle sediments, along with some minor recycled components. Also their sources were mostly intermediate-felsic igneous rocks of Archean age. The tectonic discrimination plots, Th-Sc-Zr/10 of both these formations reflect active to passive continental margin setting. Chondrite-normalized rare earth element (REE) patterns, and various trace element ratios like Cr/Th, Th/Co, La/Sc and Th/Cr indicate dominantly felsic source with minor contribution from mafic source. Th/Sc ratios of Pulivendla and Gandikota Quartzite are in close proximity with average values of 2.83, 3.45 respectively, which is higher than AUCC (Th/Sc = 0.97), demonstrating that the contributions from more alkali source rocks than those that contributed to AUCC.
