Whole Rock Geochemical Data For Paleozoic Sedimentary Rocks of the western Brooks Brooks Range, Alaska

Online link https://geo-nsdi.er.usgs.gov/metadata/open-file/2004/1371/metadata.faq.html
Description This report presents geochemical analyses for 210 unaltered and unmineralized rock samples of Paleozoic age in the western Brooks Range of northern Alaska. These data form the basis for a study by Slack et al. (2004a) on the provenance and depositional hi

CE_CE Cerium anomaly (dimensionless). The magnitude of the Ce anomaly, Ce/Ce*, is calculated as: Ce[CN]/((La[CN])**0.667 * (Nd[CN])**0.333) where Ce[CN], La[CN], and Nd[CN] represent normalization of Ce, La, and Nd respectively to average chondrites using the data of Nakamura (1974). Here two asterisks (**) are used to represent exponentiation; one alone indicates multiplication.
EU_EU Europium anomaly (dimensionless). The magnitude of the Eu anomaly, Eu/Eu*, is calculated as: Eu[CN]/(Sm[CN]*Gd[CN])**0.5 with chondrite normalization of Eu, Sm, and Gd represented respectively as Eu[CN], Sm[CN], and Gd[CN]. Here two asterisks (**) are used to represent exponentiation; one alone indicates multiplication.
