Online Investigation of an Island Arc Volcano: Anatahan, Mariana Arc
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.
What Goes into Making Volcanic Arc Magmas, and How Do We Know It?
This activity is a directed reading exercise focused on papers that have been key to our understanding of the major source contributors to subduction zone volcanic rocks.
The Woodlark Basin as a Natural Laboratory for the Study of the Geological Sciences
This activity guides the students through a set of geological problems related to the Woodlark Basin, Papua New Guinea.
Chemical Inputs and Outputs at Subduction Zones
In this exercise students utilize data from geochemistry databases to analyze inputs and outputs associated with arc volcanism.
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.
Using geochemical proxies to trace sediment sources
This lecture segments can be used in a mid- to upper-level course to introduce geochemical proxies commonly applied to weathering and sedimentation.
Tracing sediment provenance from source to sink: Isotope records in the Bay of Bengal and Indonesia
In this exercise students examine data from a geochemical database to understand the link between source rocks and sedimentary deposits in the ocean, focusing on the Bay of Bengal in the context of the MARGINS Source-to-Sink initiative and contrasting these data with those offshore of Indonesia. This activity utilizes the online geochemical database SedDB, GeoMapAPP, and Excel.
