Investigating Geochemical Diversity Along a Slow-Spreading Axis: Mid-Atlantic Ridge ~14°N
Major Advisor Name
Type of Submission
Slow spreading mid-ocean ridges, like the Mid-Atlantic Ridge (MAR), display along-axis variations in morphology and gravity that suggest robust magma supply at the segment center that diminishes towards the segment ends. By systematically sampling 145 basaltic lavas along and across-axis from the magmatic to sparsely magmatic region with DSV Alvin, this study examines the geochemical diversity along a single ridge segment of the MAR (~14°N). Major elements contents are presented for all lavas, and trace element contents are presented for 48 lavas. Geochemical analysis and petrologic modeling will provide insights into magmatic generation, storage, and transport along-axis.
