This national workshop will introduce participants to the fundamentals and applications of diffusion chronometry, a powerful tool for determining the timescales of geological and planetary processes. Aimed at planetary scientists, petrologists, and geochemists, the course will explore how diffusion profiles in minerals can be used to constrain cooling and exhumation rates, magmatic residence times, metamorphic duration, and the thermal evolution of meteorite parent bodies. Through a combination of lectures and practical exercises, participants will gain both theoretical understanding and hands-on experience in high-temperature thermochronometry, diffusion chronometry, and geospeedometry, enabling them to quantitatively link mineral-scale diffusion processes to planetary-scale thermal histories. 

Objectives

• Introduction to diffusion kinetics.

• Learning about factors controlling diffusion in minerals.

• Learning how to model diffusion-controlled chemical zoning in minerals.

• Applications to metamorphic rocks.

• Applications to planetary materials (e.g., meteorites).
