A Volcanic Record Through Time
This is a lecture segment that can be used or adapted for use in an undergraduate geoscience class. The goal of the lecture is to familiarize students with the concept of volcanic change through time at time scale commensurate to plate tectonic evolution.
Partitioning of thrust and strike/slip faulting in oblique subduction
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.
Volcanoes of Central America
Volcano distribution and tectonics at a convergent margin: Central American volcanoes
What Kind of Continental Margin am I? Active or Passive?
Volcanoes, earthquakes, and topography reveal whether a continental margin is active or passive. In this activity, students use the GeoMapApp tool to work with earthquake, volcano, and topographic data to identify ...
Historical Earthquakes and Uplift/Subsidence of Sumatra from Coral Growth Rings - Introductory Version
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.
Serpentinite in Subduction Zones: How do we find it, and how common is it?
A mineralogical, petrological, and geophysical exploration of the role of serpentinite in subduction zones, as highlighted in the two NSF-MARGINS Subduction Factory focus sites.
Burial, compaction, and porosities in a subduction zone
In this activity, students look at how sediments compact as they are buried in a subduction zone and explore how rapid burial can lead to increased water pressure.
News Flash: MARGINS Discovery Student Presentations
Students describe MARGINS research results in a two to four minute oral class presentation. The assignment is appropriate for any class that covers topics related continental margins.
Sediment production and distribution across the margins
This activity is an exploration of the relationship among tectonics, sediment production, and sediment dispersal from watersheds to the continental margins. Students will examine data on a suite of watersheds and make measurements and observations in Google Earth or GeoMapApp.
From Ocean Topography to Flexural Rigidity
Students will use the available bathymetric datasets to test the utility of a flexural rigidity model of oceanic crust.
