The importance of the Cascade Range magmatic arc in understanding the geologic evolution of western North America is widely recognized, and these arc rocks have been extensively studied. The geochemical database presented here represents the first phase of an effort to synthesize and interpret the geochemistry of Western Cascades volcanic arc rocks. Using the large and synoptic body of information in the present database, it is possible to characterize the primary geochemical attributes of the Western Cascades rocks and begin interpretation of their petrologic, tectonic, and metallogenic significance.
