A paper by Nikki Moore has been published in Contributions to Mineralogy and Petrology. Nikki did the geochemistry research for a Master of Science degree at Western Washington University with Dr. Sue DeBari, who is the second author on the paper. The paper, titled Mafic magmas from Mount Baker in the northern Cascade arc, Washington: probes into mantle and crustal processes, can be downloaded from the publisher (it costs $34.95). The paper’s abstract is posted over on the MBVRC main website, in the references (scroll down a few citations to find it).
Nikki made a geochemical study of five basaltic lavas in the Mount Baker volcanic field. She determined that the erupted magmas show evidence of their origins in two source regions of the mantle, and they have been markedly influenced by fluid given off by the subducted slab that gave rise to the melt in the first place.
