Abstract
Axial segments of the East Pacific Rise are made up of individual volcanoes. Each volcano has a distinct magma composition and shows a systematic variation in the fractional crystallization with distance along the axis from the central chamber. Hydrothermal venting, lava morphology and tectonics also vary along the axis. Lavas erupted near transform faults, from the tips of propagating rifts in overlapping spreading centres, and from near-axis seamounts have different and variable compositions.
