Ocean Island Basalt Setting: Azores Islands

Title: Ocean Island Basalt Setting: Azores Islands
Description: Geochemical Plots for the Azores Islands. Includes REE plot, ternary diagram, and multiple Harker diagrams. Some files contain more detailed interpretations and explanations for the data.

In general the harper diagrams reveal that K, Na, and Al remain as a liquid until later stages of the melts crystallization, as indicative by increasing weight percentages occurring coeval to increasing weight percentages of the control SiO2 group.

In contrast, Fe, Ca, Ti, and P2O5 decrease in weight percentage as the melt progresses, as expected for elements with higher electronegativity and smaller atomic radii.
