KEYWORDS Abstract Reconstruction of the Neoproterozoic supercontinent Rodinia shows near neighbour positions of Paleoproterozoic; the South Indian Cratons and Western Australian Cratons. These cratonic areas are characterized by extensive Supercontinent; Paleoproterozoic tectonism. Detailed analysis of the spatio-temporal data of the Satpura Mountains of India Capricorn Orogeny; indicates presence of at least three episodes of Proterozoic orogeny at w2100e1900 Ma, w1850 Ma Satpura Orogeny and w1650 Ma, and associated basin development and closing. A subdued imprint of the Grenville orogeny (w950 Ma) is also found in rock records of this Mountain Belt. The Capricorn Orogen of Western Australia also shows three episodes of orogeny: OpthalmianeGlenburgh Orogeny (2100e1950 Ma), Capricorn Orogeny (w1800 Ma) and Mangaroon Orogeny (w1650 Ma), and basin opening and closing related to these tectonic movements. These broad similarities suggest their joint evolution possibly in a near neighbour posi- tion during Paleoproterozoic Era. In view of juxtaposition of the Western Australia along the east coast of India, at the position of the Eastern Ghats, during , it is suggested that the breaking of this Archean megacraton at w2400 Ma led to northward movement of the broken components and formation of the SatpuraeCapricorn Orogen (at w2100 and w1800 Ma) due to the collision of cratonic blocks with the pre- existing northern cratonic nuclei of India and Western Australia. This is also the time of formation of the

1. Introduction fundamental implications for understanding the making and breaking of Columbia. The concept of the Neoproterozoic supercontinent Rodinia Attempts at the reconstruction of the supercontinent Gond- (Dalziel, 1991; Hoffman, 1991; Moores, 1991) has initiated interest wanaland suggested matching the east coast of India with the west to understand the nature of changes in the tectonic processes at the coast of Australia (Crawford and Oliver, 1969; King, 1973). This ArcheaneProterozoic boundary and related atmospheric and reconstruction model changed in favour of matching coastline biospheric evolutions. It is believed that the supercontinent configuration of India and East Antarctica (Crawford, 1974; assembly and disruption have a 500e600 Ma cycle possibly related Powell et al., 1988). However, analysis of the paleomagnetic to the mantle convection. Common histories of cratonic develop- and spatio-temporal data for Paleoproterozoic age indicates ment of spatially related groups of cratons apparently indicate juxtapositions of South India, West Australia and Napier Complex w relatively small intracratonic movement (w1 cm/y) and small-scale of East Antarctica at 2400 Ma (Fig. 4; Mohanty, 2010b, tectonic regimes during late ArcheanePaleoproterozoic times 2011a,b). The paleogeographic and geologic links provide (Piper, 2003). This has led to make a model of supercontinent support for this configuration (Fig. 5). The breaking and dispersal assemblies during Paleoproterozoic (Piper, 1976). From geological of the constituent elements were followed by the formation of the and paleomagnetic data it is now established that three proto- Satpura Mountains of India and the Capricorn Orogen of Western w continental nuclei: “Ur” (central South Africa, India and Australia. The Satpura Mountain Belt developed at 1800 Ma Australia), “Nena” (Fenoscandia, Laurasia and Siberia) and when the amalgamation of the North Indian Block and the South “Atlantica” (South America and Northwest Africa) had stabilised by Indian Block took place during Proterozoic time (Mohanty, w2500 Ma (Rogers, 1996; Aspler and Chiarenzelli, 1998; Condie, 2010a). This is also the time when the Pilbara and the Yilgarn 2002; Piper, 2003). Several reorganisations during the Early Pale- Cratons of Western Australia collided to form the Capricorn oproterozoic possibly formed a supercontinent “Columbia” (Rogers and Santosh, 2002) during the time period 1900e1500 Ma (Fig. 1). Lack of good quality paleomagnetic data raises several alternative possibilities of the configuration of Columbia and its dispersal to form Rodinia during the worldwide Grenvillian orogenic cycle at w1100 Ma based on geological and geochronological data (Figs. 2, 3; Condie, 2002; Zhao et al., 2002, 2004). Therefore, the transition from Paleoproterozoic to Mesoproterozoic marks an important part of the earth’s history for our understanding of Paleoproterozoic supercontinent dynamics. Early Paleoproterozoic (2100e1900 Ma) tectonism and mag- matism are restricted to South America, Africa (Doumbia et al., 1998; Hartmann et al., 1999), Canada (De et al., 2000), Baltic shield (Daly et al., 2001), Gawler craton (Daly et al., 1998), Western Australia, (Page, 1988; Windley, 1993; Sheppard et al., 2004), China and India. The correlation of some of these Paleo- proterozoic orogenic belts has the potential of generating a better picture of understanding the development of the Paleoproterozoic supercontinent Columbia. The Indian craton is divided into two blocks (the North Indian Block and the South Indian Block) by a prominent orogenic belt (the Satpura Orogen) with wENE-WSW trend in the central part of India. This orogen was earlier considered to be of Grenville (w1000 Ma) age (Bhowmik et al., 1999; Acharyya, 2001; Roy et al., 2006), and was subsequently revised to be of 1600e1500 Ma (Acharyya, 2003; Bhandari et al., 2011; Bhowmik et al., 2011). However, Mohanty (2003, 2010a) has questioned the basis of such an inference, and has shown that this mountain belt had the first orogenic imprint of w2100e1900 Ma and a second event at w1800 Ma. These orogenic trends and age data match with those of the Capricorn Orogen of Western Australia, when reconstructed for the config- uration of Columbia (Zhao et al., 2002). Therefore, the formation Figure 1 Configuration of the supercontinent Columbia (modified and evolution history of these two orogenic belts have from Rogers and Santosh, 2002). S.

In this paper an attempt is made to synthesise the Pale- for 800e1000 Ma that comprises repeated basin formation, oproterozoic tectonic evolution of the Satpura Mountains and the magmatism and orogeny in the Wilson cycle of Paleoproter- Capricorn Orogen for understanding the events associated with the ozoiceMesoproterozoic age (Tyler and Thorne, 1990).

The younger w3370 Ma (Moorbath et al., 1986; Sengupta et al., 1991). The ages are effects of zircon overgrowth during later metamorphism. mafic enclaves represent materials derived from a pre-existing The Dalma Basin which was possibly very narrow closed at mafic crust.

The second high-Mg mafic dyke swarms, development of sedimentary basins in phase of basin development (2100e2050 Ma) is marked by crustal extension, emplacement of Newer Dolerite-II (2105 38 Ma K-Ar age Mallik and Sarkar, 1994) and deposition of coarse clastics, carbonate and shale (Kolhan Group). The second orogenic episode at w1970e2030 Ma (Singhbhum Orogeny-II) was possibly asso- ciated with the development of the Singhbhum Shear Zone. This event is represented by the emplacement of Soda Granite-II (2017 Ma Pb-Pb age; Sarkar et al., 1986b) and Mayurbhanj Granite (2084 74 Rb-Sr age; Iyengar et al., 1981), and thermal imprint on the Newer Dolerite-III (2004 35 Ma and 2068 38 Ma). The phase of crustal extension of the Singhbhum Craton was associated with the emplacement of ultramafic-mafic- anorthosite plutons and Newer Dolerite-IV (1960 40 K-Ar age; Sarkar and Saha, 1977). The thermal expansion possibly gave rise to the development of Dalma Basin. It may be noted that the U-Pb zircon age of Dalma volcanic is 2396 110 Ma (Misra and Johnson, 2005) which is debatable (Roy and Sarkar, 2006). U-Pb age cluster between 1740 and 1630 Ma for the Dalma volcanic and between 1500 and 2900 Ma (mean of 2467 9 Ma) for the Chandil Formation has been reported by Mazumder et al. (2010).
