Petrology and geochemistry of the Mesoproterozoic Vattikod lamproites, Eastern Dharwar Craton, southern India: evidence for multiple enrichment of sub-continental lithospheric mantle and links with amalgamation and break-up of the Columbia supercontinent

DOI: 10.1007/s00410-018-1493-y

Abstract: Numerous lamproite dykes are hosted by the Eastern Dharwar Craton, southern India, particularly towards the northwestern margin of the Cuddapah Basin. We present here a comprehensive mineralogical and geochemical (including Sr and Nd isotopic) study… read more here.

DOI: 10.1016/j.lithos.2019.105247

Abstract: Abstract The timing of assembly into India by amalgamation of cratonic fragments, is controversial with estimates ranging from Tonian, earliest Mesoproterozoic to Neoarchean. All models have as the nucleus the South Indian Block of Dharwar,… read more here.

DOI: 10.17491/jgsi/2024/173887

Abstract: Hyderabad and its surrounding region are situated within Eastern Dharwar Craton, primarily composed of Archean granite. We use ambient noise tomography to obtain the 3-D shallow subsurface shear seismic velocity structure of 150 x 200… read more here.

DOI: 10.17491/jgsi/2025/174184

Abstract: The cratonic regions of the Indian Shield host numerous Precambrian lamproites. A majority of these lamproites are dated at Mesoproterozoic (1070-1434 Ma) using whole-rock 40Ar-39Ar, zircon U-Pb, and mica K-Ar and Rb-Sr geochronology methods. This… read more here.

DOI: 10.18520/cs/v118/i9/1420-1431

Abstract: The Eastern Dharwar Craton (EDC) in southern India comprises several thin, linear N–S and NW–SE trending greenstone belts that hold rich economic mineral deposits, surrounded by gneisses and granites of different ages. Very long, linear,… read more here.
