“…These assumptions are mostly based on the high-quality paleomagnetic results from various Indian cratons. Belica et al (2014) have reviewed the drift history of Dharwar craton during Paleoproterozoic times (2.37-1.88 Ga), which provided four new key poles for India (Dharwar). The position of India in the Columbia supercontinent has also been discussed (Belica et al, 2014;Pisarevsky et al, 2014).…”

“…However, in a recent publication, Kumar et al (2015) have suggested that a reconstruction of the paleopositions of Dharwar and Superior at ~2080 Ma does not suggest a close proximity for these provinces at that time. On the basis of new paleomagnetic and geochronologic results from the Dharwar craton, Belica et al (2014) have presented a Paleoproterozoic Apparent Polar Wander Path (APWP) for the Dharwar craton, and examine paleogeographic relationships between India and other cratonic blocks for the 2.37-1.88 Ga time interval. In a recent review, based on available geochemical and geochronological data, Srivastava et al (2015) have believed that the Dharwar and North Atlantic cratons coexisted at 2.37 Ga and no similar event is reported for any other craton.…”

Major highlights of researches carried out on kimberlites, lamproites, lamprophyres, carbonatites, other alkaline rocks and mafic dykes from the Indian shield during 2012-2016 are presented. New findings involving field mapping, petrology, geochemistry (including high quality mineral based in situ isotopic studies) and geophysics have provided remarkable insights on the mode of their occurrence, timing of emplacement, mineralogy and bulk-rock composition, redox conditions, relative contribution of the lithosphere and asthenosphere, as well as their economic potential. Several large-scale geodynamic aspects such as plume-lithosphere interactions, ancient subduction events, layered structure of the sub-continental lithospheric mantle, spatial extent of the Precambrian large igneous provinces and supercontinent configurations could be unraveled from these studies on deep-mantle derived small-volume magmatic rocks.

Paleoproterozoic mafic intrusive rocks from the western Arunachal Himalaya have been studied for understanding their petrogenesis and tectonic environment, in which they were emplaced, with the help of their bulk-rock major, trace, and rare-earth elements (REE) compositions. These mafic intrusive rocks, mostly small bodies of dykes, sills, and lenses, are exposed in the Higher as well as the Lesser Himalaya sequences. Geochemically, 2 suites of rocks are identified and grouped into high-titanium and low-titanium mafic intrusive rocks. High-titanium mafic intrusive (HTMI) samples have comparatively low Mg number (Mg#) and high high-field strength element contents in comparison to low-titanium mafic intrusive (LTMI) rocks. Multielements and REE patterns for these two identified groups are distinct. The LTMI and HTMI were originally spatially separated at the time of their emplacement and believed that probably they have been juxtaposed during the Himalayan orogeny by crustal shortening through development of imbricated thrusts. It is perceived that the HTMI and LTMI have different petrogenetic histories and are derived from two different melts; however, they are postulated to be parts of the same igneous province. Geochemical characteristics do not support any serious effect of crustal contamination; however, interaction with metasomatized lithospheric mantle cannot be discounted. Trace element petrogenetic modelling suggests derivation of the LTMI samples from a parental magma generated in spinel stability field (thin lithosphere) through a~20-25% melting of a lherzolite mantle source, whereas the HTMI samples were derived from~5-10% melting of a similar mantle source but from garnet stability field (thick lithosphere). Widespread Paleoproterozoic mafic events in the Indian shield such as Bastanar dyke swarm in the Bastar and the Hampi dyke swarm (also includes Pulivendla sills in the Cuddapah Basin) in the eastern Dharwar Craton together with mafic intrusive and extrusive rocks in the Himalayan region suggest presence of a large igneous province at~1.9 Ga.

Geochemistry, petrogenesis, and geodynamic implications of NE–SW to ENE–WSW trending Palaeoproterozoic mafic dyke swarms from southern region of the western Dharwar Craton

A number of NE–SW to ENE–WSW trending Palaeoproterozoic mafic dykes, intruded within the Archean basement rocks and more conspicuous in the southern parts of the western Dharwar Craton (WDC), was studied for their whole‐rock geochemistry to understand their petrogenetic and geodynamic aspects. Observed mineralogical and textural characteristics classify them either as meta‐dolerites or dolerites/olivine‐dolerites. They show basaltic to basaltic–andesitic compositions and bear sub‐alkaline tholeiitic nature. Three geochemically distinct groups of mafic dykes have been identified. Group 1 samples show flat REE patterns (LaN/LuN = ~1), whereas the other two groups have LaN/LuN = ~2–3 (Group 2; enriched LREE and flat HREE patterns) and LaN/LuN = ~4 (Group 3; inclined REE patterns). Chemistry is not straightforward to support any significant role of crustal contamination and probably reflect their source characteristics. However, their derivation from melts originated from a previously modified metasomatized lithospheric mantle due to some ancient subduction event cannot be ignored. Most likely different mantle melts were responsible for derivation of these distinct sets of mafic dykes. The Group 2 dykes are derived from a melt generated within spinel stability field by ~10% batch melting of a lithospheric mantle source, whereas the Group 3 dykes have their derivation from a melt originated within the spinel–garnet transition zone and were fed from slightly higher (~12–15%) batch melting of a similar source. The Group 1 samples were also crystallized from a melt generated at the transition zone of spinel–garnet stability field by higher degrees (~20%) of melting of a primitive mantle source. Geochemistry of the studied samples is typical of Palaeoproterozoic mafic dykes emplaced within the intracratonic setting, reported elsewhere globally as well as neighbouring cratons. Geochemistry of the studied mafic dyke samples is also compared with the mafic dykes of the eastern Dharwar Craton (EDC). Except the Group 3 samples, which have good correlation with the 1.88–1.89 Ga Hampi swarm, no other group shows similarity with the EDC mafic dykes. There is an ample possibility to have some different mafic magmatic events in the WDC, which could be different from the EDC. However, it can only be confirmed after precise age determinations.
