Part of Cascade Volcanic Arc: Alumina Saturation Indices and Total Alkali vs Silica

Title

Alumina Saturation Indices: Cascade Volcanic Arc

Description

This plot shows that nearly all of the samples from the Cascade Volcanic Arc are peraluminous. There are a few samples outside of this category, but I suggest that they are erroneous, as the total alkali values for these samples are less than 1.
