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]
Geodynamic models and landscape evolution models are becoming important tools to quantify the formation and development of paleogeographic features, contributing to our understanding of the patterns of biodiversity evolution. Earth, a dynamic system The Earth’s surface works as a dynamic system and is continuously sculpted through the geological timescale by weathering, wind, rivers, and many othe ...[Read More]
As a result of Earth’s mantle convection, rocks in the earth’s interior flow and develop a crystallographic texture. These textures reveal the planet’s thermal and tectonic history and are responsible for the viscous anisotropy, which can be used to study the planet’s deeper recesses that are not visible through other means. This necessitates the use of models that can pred ...[Read More]
The Geodynamics 101 series serves to showcase the diversity of research topics and/or methods in the geodynamics community. In this week’s post, Fred Richards explains how ‘Dynamic Topography’ is used in the Geosciences, and discusses the knowns, unknowns, and the challenges ahead. Since shortly after its tumultuous formation 4.5 billion years ago, Earth has been steadily cooling, wit ...[Read More]
