Many students view equations as a series of variables and operators into which numbers should be plugged rather than as representative of a physical process. To solve a problem they may simply look for an equation with the correct variables and assume it meets their needs, rather than selecting an equation that represents the appropriate physical process. These issues can be addressed by encouraging students to think of equations as stories, and to describe them in prose. This is the goal of the Equation Dictionary project, used in Western Washington University's introductory geophysics course. Throughout the course, students create personal …
The Generation Of A Diverse Suite Of Late Pleistocene And Holocene Basaltic-Andesite Through Dacite Lavas From The Northern Cascade Arc At Mount Baker, Washington, Troy D. Baggerman
The Generation Of A Diverse Suite Of Late Pleistocene And Holocene Basaltic-Andesite Through Dacite Lavas From The Northern Cascade Arc At Mount Baker, Washington, Troy D. Baggerman

This study highlights geochemical diversity in a spectrum of basaltic andesite through dacite lavas from Mount Baker, WA, and describes processes that are responsible for their generation. Petrographic observations, mineral chemistry, along with whole rock major oxide concentrations, and trace and REE data are provided for three Late Pleistocene and Holocene lava flows: the basaltic andesite of Sulphur Creek (SC) (52.5-55.8 wt.% Si02, Mg# 57-54), the andesite of Glacier Creek (GC) (58.3-58.7 wt.% Si02, Mg # 63-64), and the andesite and dacite of Boulder Glacier (BG) (60.2-64.2 wt.% Si02, Mg # 50-57). Major oxide concentrations for SC and BG display …
