Physical and Chemical Variations Along the Central American Volcanic Arc part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
The Central American volcanic arc displays large arc-parallel variations in chemical composition that yield important clues concerning the complex origin of magmas in subduction zones. In this exercise, students use data compiled for the NSF MARGINS program to compare heights, volumes, and whole-rock compositions of 39 Quaternary volcanic centers along the Central American arc, together with crustal thicknesses, to assess the possible sources of the magmas and the petrologic processes that have modified them prior to eruption.
Identifying Minerals with Chemical and Crystallographic Data part of Cutting Edge:Mineralogy:Activities
In this exercise, crystal structure data for a variety of unknown minerals are downloaded and entered into XtalDraw or CrystalMaker visualization software program. Step-by-step tutorials are provided with ...
Compositional Diversity in Volcanic Suites part of Cutting Edge:Geochemistry:Activities
In this exercise, students use geochemical data downloaded from the GEOROC database to explore the origins of compositional variation among volcanic rocks associated with the Yellowstone and Crater Lake calderas.
Crystal Structures as Geobarometers part of Cutting Edge:Mineralogy:Activities
In this exercise, designed for undergraduate igneous petrology or advanced mineralogy courses, students download a series of crystal structures from the American Mineralogist Crystal Structure Database to explore ...
Olivine Crystal Structure part of Cutting Edge:Mineralogy:Activities
In this exercise, students use the American Mineralogist Crystal Structure Database and a crystallographic visualization program such as Xtaldraw or CrystalMaker to study the temperature-dependent ordering of Mg ...
Crystallization-Differentiation of Basaltic Magma part of Cutting Edge:Geochemistry:Activities
In this exercise, students use geochemical data from volcanic glasses and minerals in lavas and drill cores from the solidified Kilauea Iki lava lake to learn about the petrologic processes related to the eruption ...
The Cretaceous Superplume part of Integrating Research and Education:Cretaceous
This page was written by Kent Ratajeski as part of the DLESE Community Services Project: Integrating Research in Education. A satellite gravity and bathymetric map of the Ontong-Java plateau, an igneous province ...
