Fractionation of abyssal tholeiites: samples from the Oceanographer Fracture Zone (35°N, 35°W)
Abstract
Chemical analyses of 48 fresh abyssal tholeiite specimens sampled from two dredge localities clearly define systematic chemical differences which indicate a moderate iron-enrichment trend of fractionation oblique to the FeO 2O, P 2O 5 and TiO 2. These results suggest that fractionation may be important in controlling the chemistry of abyssal tholeiites along sections of the mid-oceanic ridge.
