Chemistry of the lavas of the 1959-60 eruption of Kilauea Volcano, Hawaii

During the 1959-60 eruption of Kilauea Volcano, the outpouring magma was sampled systematically to obtain detailed information on chronological changes in composition. The temporal variations in composition, when correlated with mineralogy, lava temperature, rate of discharge, and other parameters measured during the eruption, provide new insight into the preeruptional crystallization of basaltic magma, entailing intratelluric depositions of various phenocrysts and migration of rest liquids.
