Ankaramites are lavas erupted at shield volcanoes when their magmas become differentiated. They typically contain a large portion of clinopyroxene and olivine phenocrysts.
My investigation of clinopyroxene phenocrysts in Maui ankaramites (Hawaii) has revealed cryptic processes of rapid crystal growth and sector zoning in this mineral.
These observations have profound effects on the timescales of crystallization, the inferred thermobarometry and the overall magma dynamics at Haleakala volcano.
