Petrogenesis of high-Mg andesites from the Proterozoic Shillong Basin, Northeast India: evidence for continuation of the Central Indian Tectonic Zone to the Assam-Meghalaya Gneissic Complex and its implications for the Columbia supercontinent reconstruction Open
This study provides comprehensive geochemical and petrological data for the newly discovered high-magnesium andesites (HMAs) from the Shillong Group of rocks in the Proterozoic Shillong Basin of the Assam-Meghalaya Gneissic Complex (AMGC).…

Geochemistry, Petrogenesis and Tectonic Setting of the Mafic Dykes from the Amgaon and Khairagarh Regions, Bastar Craton, Central Indian Shield: Constraints on the Precambrian Crustal Evolution Open
The presence of dominantly dykes, dyke swarms and sills along with the basement rocks indicate that the study area has undergone deep erosion exposing the basement rocks and these magmatic bodies (dykes, dyke swarms and sills) actually rep…

View article: Role of viscous swirling in the formation of magnetite ocelli or fleck structure in the migmatites of Shillong Plateau Gneissic Complex, eastern India
Role of viscous swirling in the formation of magnetite ocelli or fleck structure in the migmatites of Shillong Plateau Gneissic Complex, eastern India Open
The quartzofeldspathic gneiss of the Shillong Plateau Gneissic Complex has preserved magnetite-centered ocellar texture or fleck structure. Results presented in this work suggest that the intrusion of hot, volatile-rich pegmatitic magma in…

Origin of porphyritic texture by magma mixing in the andesitic rocks of Ghansura Rhyolite Dome from the Bathani volcano-sedimentary sequence, Eastern India Open
The Ghansura Rhyolite Dome (GRD) of Bathani volcano-sedimentary sequence in Eastern India provides direct evidence for mafic-felsic magma interaction during its evolution. The interaction led to the formation of different varieties of hybr…

Viscous dilation as a mechanism of magma mixing in the Ghansura Rhyolite Dome of Bathani volcano-sedimentary sequence, Eastern India Open
The comingled mafic-felsic rocks of the Ghansura Rhyolite Dome of Bathani volcano-sedimentary sequence, eastern India, have preserved veins of iron oxide. These veins are transporting iron oxide from the mafic zones into the adjacent felsi…
