Geodynamic modelling helps us understand Earth’s internal processes by providing a framework to test hypotheses. Analogue modelling uses physical models governed by the laws of nature, with resolution down to Planck’s length. In contrast, numerical modelling employs mathematical methods to approximate solutions to the physical laws governing Earth’s processes. Each modelling approach comes with it ...[Read More]

Effects of decelerating India-Eurasia convergence on the crustal flow and topographic evolution of the Tibetan Plateau

The Tibetan Plateau is the most extensive elevated surface on the Earth, stretching ~1,000 km north to south and 3,200 km east to west, with a mean elevation of greater than 4.5 km and located north of the Indian subcontinent. The formation of this Plateau has profoundly influenced the variations and evolution of Asian climate, strengthening of the South-Asian Monsoon, development of the large Asi ...[Read More]

Ahhh analogue models… Those beautiful little (or not so little) worlds inside a box, captivatingly beautiful, impossibly detailed… (sorry, getting carried away, am I?). This week, Alex Hughes gives us the insider’s report on what actually goes on in analogue modelling labs when the “Experiment running, do not disturb!!” sign is on the door. Analogue models have been a ...[Read More]
