Upper and Lower limits of timescales accessible by Diffusion Chronometry

Diffusion chronometry makes use of concentration gradients to determine timescales (as examples - durations of residence in thermal reservoirs, rates of cooling or ascent) of geological and planetary processes. The governing relationship that underlies the method is that the diffusion distance (x) scales with the square root of time (t), so that ...

Complex Zoning Patterns of Skeletal Olivine in Yangyuan Alkaline Basalt: Implications for Diffusion Chronometry and Crystallization Dynamics

Journal of Petrology
Abstract Olivine is a pivotal mineral for decoding magmatic processes; however, its compositional and textural complexity—particularly in disequilibrium settings—complicates the interpretation of magma histories. A critical unresolved challenge is distinguishing the respective contributions of rapid crystallization and ...

From Magmatic Unrest to Eruption: Insights from Diffusion Chronometry in Iceland and Hawai‘i

Understanding when and how magmatic systems evolve toward eruption is key to forecasting and hazard mitigation. This study applies diffusion chronometry to two basaltic rift eruptions - the 2021 Fagradalsfjall eruption in SW Iceland [1] and the 1950 Mauna Loa SWRZ eruption in Hawai‘i [2] - to constrain the timing of magma mobilization, mush ...
