The Crustal Evolution of Nilgiri Block, Southern India : A Study on Archean Tectonics and Crustal Growth
(2018-08-02)The oldest dated rocks from the Acasta gneisses of the western Slave Province, Canada present an igneous age of ~4030 Ma. Following this the detrital zircons from the Jack Hills, Narryer Gneiss Terrane, Yilgarn Craton, ... -
Lab Experiment Documenting Growth of Microbes in an Extreme Condition
Bacterial population during 3.2 billion years of early earth was responsible for modifying the greenhouse gas concentration in the early earth. Here we studied the primitive facultative anaerobe E.coli K12, known to contain ... -
MHD Waves Driven by Small-scale Motion and Implications for the Earth's Core
(2018-05-22)Rotating convection in the Earth's core produces columnar vortices of radius ~10 km or less near the inner core boundary. Small-scale motions in the core can travel as Alfvén waves in the face of Ohmic diffusion, provided ... -
Tectonic Evolution of Central Madurai Block, Southern India and Potential Heat Source for High-Temperature Metamorphism
(2018-01-29)The Madurai Block is the largest granulite block in Southern Granulite Terrain which lies between Palghat-Cauvary shear zone in the North and Achankovil shear zone in the South. This terrain underwent extreme crustal ...
