|Exploring Geochemistry in the Classroom Using GEOROC Data|
This guide provides instructions for educators on the classroom use of the Geochemistry of Rocks of the Oceans and Continents (GEOROC) database. GEOROC provides chemical and isotopic data for rocks, minerals, and melt/fluid inclusions that are used by scientists for a variety of purposes, including analysis and classification of samples, comparison of similar rocks from different parts of the world, and comparison of compositionally varied rocks from geographically similar settings. Teaching topics include volcanic and plutonic igneous rocks; mantle xenoliths; volcanic glasses; metamorphic rocks; and glass, mineral, or fluid inclusions. Students will learn to generate graphs from raw data; interpret petrological data, including chemical composition; and investigate the role of plate tectonics in the formation of igneous rocks. There are instructions for accessing and manipulating the data, links to scientific and educational resources that use this dataset, and links to online resources with related information.
