Serpentine Seamounts in the Mariana Forearc: Shallow Material Releases from Downgoing Plates part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
A set of maps, images and .kmz files for use in lectures and discussions on forearc serpentine volcanism in the Mariana subduction system.

Online Investigation of an Island Arc Volcano: Anatahan, Mariana Arc part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This activity is a Web investigation and research exercise starting with the 2003-present Anatahan volcanic eruptions in the Mariana arc, and concluding with a petrologic examination of published Mariana arc lavas data sets.

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.

Profiling Earth's Surface using GeoMapApp part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
In this exercise, students relate large-scale features on Earth's surface to lithospheric plates, the underlying asthenosphere, earthquakes, and volcanoes. After creating a cross section showing elevation using GeoMapApp, students add additional features by hand.

What Can (and Cannot) Be Learned from Scientific Drilling Using Examples from Margins Initiatives part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This is a lecture segment that could be introduced to an introductory geoscience class to help explain and demonstrate what can and cannot be found out by scientific drilling.

Chemical Inputs and Outputs at Subduction Zones part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
In this exercise students utilize data from geochemistry databases to analyze inputs and outputs associated with arc volcanism.

Historical Earthquakes and Uplift/Subsidence of Sumatra from Coral Growth Rings - Introductory Version part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
In this lab, students will use data from real corals collected in Sumatra to date historical earthquakes and to track the history of uplift and subsidence of the region over the past century.

Source to Sink Morphology, Sedimentation, and Anthropogenic Impact: Hudson System, New York part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Familiarize students with the morphology of passive continental margins and their associated shelf valleys, submarine canyons and estuaries, and assess the anthropogenic impact.

Partitioning of thrust and strike/slip faulting in oblique subduction part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Oblique subduction results in distinct sets of faults with either just thrust or mainly strike/slip motion and that back-arc thrust belts show little oblique strain compared to forearc areas.

Margin Morphology: Does Form Follow Function? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Students will use GeoMapApp to investigate variations in the geomorphology of continental margins – both Passive and Active – at various sites of the North American and South American continents. They will ...
