Abstract
Archean komatiites are the hottest magmas preserved
on Earth and are thus unique probes of its thermal
evolution. Estimating their eruption temperatures remains
problematic, however, because the uppermost (A1, A2)
zones of komatiite flows contain randomly oriented spinifex-textured
olivines, indicative of rapid cooling and
growth.
