Redox state of Archean surface environments: Insights from the Banded Iron Formations (BIFs) of the Western Dharwar Craton, Southern India  Open
The interplay of geological, chemical and biological processes that drive the oxygenation of the oceans-atmosphere of the early earth are spatially linked to the emergence of biosphere. Banded Iron Formations (BIFs) from the Archean greens…

Water content in primary magma compositions and mantle source of chromitites in Mesoarchean Nuggihalli greenstone belt (India) Open
Chromitites, found in Archean greenstone belts as the oldest ultramafic rocks, offer critical insights into the early Earth's evolution. Water plays a fundamental role in aggregation and mineralization of chromite, yet the water content of…

Horizontal tectonics assembled unrelated crustal blocks in the Paleoarchean Open
Archean geodynamics and craton formation are topics of much debate for decades. Here we present evidence from field, petrography, geochronology, elements and Nd-Hf isotopes for origin of micro-blocks in different geodynamic environments an…

About this title - Archean Granitoids of India: Windows into Early Earth Tectonics Open
Granitoids form the bulk of the Archean continental crust and preserve key information on early Earth evolution. India hosts five main Archean cratonic blocks (Aravalli, Bundelkhand, Singhbhum, Bastar and Dharwar). This book summarizes the…
