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 ...
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 ...
