Major element, trace element, and isotope data of mineral separates from abyssal peridotites and basalts from the Eastern part of the South West Indian Ridge v.2

The Marion Rise (MR) at the central Southwest Indian Ridge (SWIR) is an ultra-slow spreading ridge with thin crust, shallow ridge depth, sparse basaltic coverage, and exposed peridotite. Here we analyzed basalts for major and trace elements, and Nd and Hf isotopes. Data for Nd and Hf isotope data of both clinopyroxenes from abyssal peridotites and basalts show decoupled Hf-Nd isotope systematics.
