MORB geochemistry (Claire, Hana and Ryan)

Description
-
MORB geochemistry is characterized as being low in incompatible elements. This is because the mantle source rocks for the melt that creates the MORBs is low in incompatibles. In other words MORBs have depleted source rocks. As a result MORB REE diagrams are have a flat slope. MORB Harker diagrams share similar trends to Harker diagrams from other tectonic settings. MORB Harker diagrams correlated positively with Al2O3, K2O, and Na2O. They correlated negatively with TiO2, FeO, MgO, CaO and P2O5.
