Regional viscosity variations in Earth’s mantle

Regional viscosity variations in Earth’s mantle

For understanding the dynamics and evolution of the Earth’s mantle, knowledge of mantle’s viscosity structure is very important. In this week’s blog, Kenneth Gourley from University of Arizona discusses the variation of viscosity structure in Earth’s mantle in regional scale.   In order to understand the dynamics and evolution of the Earth’s mantle, geodynamicists model mantle fl ...[Read More]

Rayleigh-Taylor instability in geodynamics

Rayleigh-Taylor instability in geodynamics

Flow against gravity is a common feature in the geodynamic phenomenon. In this week’s Geodynamics 101, Dip Ghosh from Jadavpur University Geodynamics Lab will explain the fundamentals of Rayleigh-Taylor instability: A key to understanding the anti-gravity flow. It has long been realized that most of the geodynamic processes can be described in terms of slow viscous flow. Thus, like many othe ...[Read More]

The Sassy Scientist – Jekyll and Hyde

The Sassy Scientist – Jekyll and Hyde

Every week, The Sassy Scientist answers a question on geodynamics, related topics, academic life, the universe or anything in between with a healthy dose of sarcasm. Do you have a question for The Sassy Scientist? Submit your question here. Senna asks: I’m torn between mantle dynamics and lithosphere dynamics as a research topic. Which shall I choose? Dear Senna, Could you follow my little Jekyll ...[Read More]
