Abstract:

Sample and whole rock chemistry and isotopic data for Eocene to Cretaceous plutonic samples in NE Washington, USA. Samples were collected as a part of undergraduate thesis projects and are compiled here as a component of a paper submitted to GSA Bulletin. Data include major and trace whole rock analyses, Sr-Nd-O isotope analyses, and U-Pb zircon ages. Data are used to better understand changes in magmatic activity between the Cretaceous-Paleogene arc, the Eocene "Challis Episode," and the modern Cascade arc.
