dc.description.abstractMineral chemical analyses of transitional basalts from the Carlsberg Ridge show plagioclase (An approximately 87 mole %), phenocrysts, and microphenocrysts have a K sub(2)O depletion as compared to the laths (approximately 79 mole %). Olivine (approximately 91 mole %) are few and rarely zoned. The composition of plagioclase and olivine indicate low pressure equilibrium crystallization. The basalts were probably derived through fractional crystallization at shallow depths under low partial melting conditions. Morphology of plagioclase phenocrysts and bulk rock chemistry suggest magma mixing and fractional crystallization for the origin of these basalts
