Boninitic metavolcanic rocks and island arc tholeiites from the Older Metamorphic Group (OMG) of Singhbhum Craton, eastern India: Geochemical evidence for Archean subduction processes
Manikyamba, C.; Ray, J.; Ganguly, S.; Singh, M.R.; Santosh, M.; Saha, A.; Satyanarayanan, M. (Elsevier, 2015)The metavolcanic rocks of the Paleo-Mesoarchean Older Metamorphic Group (OMG) from Jagannathpur area of the Singhbhum Craton occur as enclaves within the Singhbhum granites (SBG). The primary mineralogical composition of ... -
Geochemical cycling during subduction initiation: Evidence from serpentinized mantle wedge peridotite in the south Andaman ophiolite suite
Saha, A.; Santosh, M.; Ganguly, S.; Manikyamba, C.; Ray, J.; Dutta, J. (Elsevier, 2018)The ophiolite suite from south Andaman Islands forms part of the Tethyan Ophiolite Belt and preserves the remnants of an ideal ophiolite sequence comprising a basal serpentinized and tectonised mantle peridotite followed ... -
