Terra Nova: Timing of partial melting and granulite formation during the genesis of high to ultra-high temperature terranes: Insight from numerical experiments

by

Long-lived high to ultra-high temperature (HT-UHT) granulitic terranes formed throughout Earth’s history. Yet, the detailed processes involved in their formation re- main unresolved and notably the sequence of appearance and duration of migmatisa- tion and granulites conditions in the orogenic cycle. These processes can be evaluated by analytical and numerical models. First, solving the steady-state … Read more…

Scientific Reports: Constraining the response of continental‐scale groundwater flow to climate change

by

Numerical models of groundwater flow play a critical role for water management scenarios under climate extremes. Large‐scale models play a key role in determining long-range flow pathways from continental interiors to the oceans, yet struggle to simulate the local flow patterns offered by small‐scale models. We have developed a highly scalable numerical framework to model … Read more…

Marine and Petroleum Geology: Single-phase vs two-phase rifting: Numerical perspectives on the accommodation of extension during continental break-up

by

How continental lithosphere responds to extension is a function of the dynamic interaction between layers of differing rheological properties, including the shallow crust, deep crust, lithospheric mantle, and asthenosphere. We investigate the first-order controls on the modes of extension and timing of transition from continental rifting to development of continental margins via a suite of … Read more…
