Crustal inheritance and a top-down control on arc magmatism at Mount St. Helens

Creator:

Bedrosian, Paul A., Peacock, Jared R., Bowles-Martinez, Esteban, Schultz, Adam, and Hill, Graham

Abstract:

In a subduction zone, the volcanic arc marks the location where magma, generated via flux melting in the mantle wedge, migrates through the crust and erupts. While the location of deep magma broadly defines the arc position, here we argue that crustal structures, identified in geophysical data from the Washington...

Meeting of the magmas : the evolutionary history of the Kalama Eruptive Period, Mount St. Helens, Washington

Creator:

Lieuallen, Athena Erin

Abstract:

Comprehension of eruptive histories is critical in understanding the evolution of magmatic systems at arc volcanoes and may supply evidence to the petrogenesis of intermediate and evolved magmas. Within the 300 ka eruptive history of Mount St. Helens, Washington, the Kalama Eruptive Period, 1479- ~1750 CE was bracketed by interludes...
