The study proposes a geochemical, petrogenetic, and metallogenetic study of Neoarchean Malanjkhand Granitoid, Dongargarh Supergroup volcanics and plutons along the Kotri Dongargarh Mobile Belt (KDMB) in the Malanjkhand extension area of Central Indian Craton. The scope of the work includes collecting volcanic and plutonic rock samples, petrography, and analysis using advanced analytical equipment such as scanning electron microscope (SEM), inductively coupled plasma mass spectrometer (ICP-MS), Laser Ablation high resolution ICP-MS (LA-HR-ICP MS), and electron probe micro analyzer (EPMA). The integrated petrogenetic and tectonostratigraphic model of the region is envisaged to help understand the Neoarchean crustal evolution and metallogeny in the Central Indian craton. Recent studies suggest that Dongargarh and Malanjkhand granite, Nandgaon bimodal volcanics, and Khairagarh mafic volcanics are related to large-scale rifting and subduction along KDMB, similar to modern tectonic plates. The study proposes an updated petrogenetic model of this belt with trace and REE composition of these relict magmatic minerals. The chemical stratigraphy of relict mineral phases can provide an independent insight into the genesis of these Neoarchean volcanic suites. The refined petrogenetic model developed from this study will help understand the genetic relation of coeval volcanics and plutons in Neoarchean times in the Dongargarh-Malanjkhand region and better understand the cause of metallogeny in such complex geological terrain.
