Bored by the Lower Mantle? Think Again!

Bored by the Lower Mantle? Think Again!

Is the lower mantle boring? For a long time, the lower mantle was thought to be relatively featureless and uniform compared to the more dynamic upper mantle. But recent seismic observations are challenging that idea, especially when we look near the base of the mantle. Recent studies from Maureen Long’s group (Creasy et al. 2017, …[Read More]

Journey Towards the Centre of the Earth: The Secret Behind the Long-Term Survival of Large Low-Velocity Provinces

Journey Towards the Centre of the Earth: The Secret Behind the Long-Term Survival of Large Low-Velocity Provinces

Geophysicists have long been intrigued by the enigmatic “blobs” residing deep within Earth’s lower mantle — the Large Low-Velocity Provinces (LLVPs). Ever wondered what keeps these gigantic thermochemical structures surviving for billions of years despite the mantle’s vigorous convection? In this week’s News & Views, Prachi Kar, a PhD candidate from Arizona State University, delves …[Read More]

Simulating the Deep Earth with MAGEMin: A Toolkit for Thermodynamic Modeling in Geodynamics

Simulating the Deep Earth with MAGEMin: A Toolkit for Thermodynamic Modeling in Geodynamics

Understanding how rocks melt, deform, and evolve within Earth’s interior is a central challenge in geoscience. These processes span a wide range of spatial and temporal scales and are governed by complex interactions between temperature, pressure, composition, and phase stability. Capturing this complexity in numerical models requires integrating mineral thermodynamics directly into geodynamic modeling frameworks. MAGEMin …[Read More]
