Activities (2)

Using geochemical proxies to trace sediment sources part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This is a series of lecture slides on how sediment geochemistry is used to obtain information about surface processes. The student is introduced to geochemical proxies, some applications, and is shown an example using strontium isotope distribution in the Bay of Bengal.

Chemical Inputs and Outputs at Subduction Zones part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
In this activity the student analyzes global geochemistry data to create hypotheses regarding possible geochemical inputs at subduction zones, and the range of compositions associated with this type of convergent boundary. The exercise utilizes the EarthChem federation of online geochemical databases, GeoMapApp and Excel. The activity focuses on Central America, an NSF-MARGINS Focus Site, and Cascadia, an NSF-MARGINS allied study site.
