Megan D’Errico’s paper on Gakkel peridotites published

Megan D’Errico’s paper on the geochemistry of peridotites from the Arctic Ocean has been published in Geochimica et Cosmochimica Acta. Based on modeling of peridotite compositions, we show that the presence of refractory harzburgites and thin overlying oceanic crust are best explained by low degrees of melting of a previously melted, heterogeneous mantle.
