Paleoproterozoic calc-alkaline lamprophyres from the Sidhi Gneissic complex, India: Implications for plate tectonic evolution of the Central Indian Tectonic Zone
Calc-alkaline lamprophyres are widely regarded as important probes for unravelling
continental-scale geodynamic processes. We present petrographic, mineral chemical, bulk …

~ 2.5 Ga asthenospheric-melt impregnated continental crust: Implications for sporadically eroded lithosphere beneath the Dharwar craton, India
TC Khanna, SH Jaffri - Precambrian Research, 2021 - Elsevier
In an intraplate continental setting, asthenospheric melts emplaced at the surface usually
exhibit lithospheric interaction and crustal contamination signatures. In such a scenario, the …
