Crystal growth is often described as either interface-controlled or diffusion-controlled. Here, we study crystal growth in an intermediate scenario where reaction rates at the crystal-melt interface are similar to the rates of diffusive transport of...

The permeability of loose magma mush (2023)
Journal Article
Bretagne, E., Wadsworth, F. B., Vasseur, J., Humphreys, M. C., Dingwell, D. B., Dobson, K. J., Mangler, M. F., & Rooyakkers, S. M. (2023). The permeability of loose magma mush. Geology, 51(9), 829-832. https://doi.org/10.1130/g51133.1

Models for the evolution of magma mush zones are of fundamental importance for understanding magma storage, differentiation in the crust, and melt extraction processes that prime eruptions. These models require calculations of the permeability of the... Read More about The permeability of loose magma mush.
