Prevailing scientific wisdom tells us that volcanic seamounts and oceanic islands are forged from magma hotspots fed by mantle-derived plumes. […]
Seamounts and volcanic islands – the foundations for atolls and fringing reefs. A historical interlude Darwin’s elegant explanation of atoll
Every geological outcrop tells a story. How often do you pass a road-side rock outcrop that grabs your attention, a
This post focuses on sandbox models and what they tell us about the mechanics and kinematics of orogenic wedge development.
Brittle deformation and Mohr-Coulomb failure Deformation of Earth materials takes place predominantly within two rheological domains: brittle and ductile. Deformation
Calculating normal stress and shear stress using Mohr circles Deformation of rock, sediment, and soil is usually manifested as a
Sandbox analogue models of strike-slip basins and pop-up structures How things have changed. It wasn’t that long ago that numerical
This post deals with the materials, their rheological behaviours, and scaling as they apply to analogue structure models. Rock deformation
The correct scaling of geometric, dynamic, and kinematic system variables is a critical part of any useful analogue model. Most
The posts in this series focus on Earth science models, particularly the soft-rock kind. I have an abiding memory of
