Geospeedometry
Geospeedometry is the science of measuring the timescales and/or temperatures of thermal events in the history of a metamorphic or igneous rock using diffusion profiles of elements within individual minerals. "Geospeedometry" refers to the speed, or timescale, of thermal events in geologic materials. The term first appeared in the literature in 1983; prior thermochronometric studies focused on diffusion of iron and magnesium in olivine provided the foundation for the field. Geospeedometry has since developed rapidly as further studies have experimentally calibrated the diffusivity of elements in various minerals.
