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.
A tour of the Mariana Subduction System
This lesson presents a brief tour of the Mariana subduction system, an active continental margin in the west Pacific.
Historical Earthquakes and Uplift/Subsidence of Sumatra from Coral Growth Rings -- Advanced Version
In this lab, students will use data from real corals collected in Sumatra to track the sea-level and earthquake record of the region over the past century.
A Geologic Safari of the East African Rift and the Newark Basin: Why these areas are more alike than you know
This activity explores the similarity and differences between the Newark Rift Basin and East African Rift.
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.
Plate Tectonics as Expressed in Geological Landforms and Events
This activity seeks to have students analyze global data sets on earthquake and volcano distributions toward identifying major plate boundary types in different regions on the Earth. A secondary objective is to familiarize students with two publicly available resources for viewing and manipulating geologically-relevant geospatial data: Google Earth(TM) and GeoMapApp.
Sediments and carbon burial on the continental margins
This lesson explores factors that control the character and fate of carbon delivered by rivers from the continents to the oceans, using mapped characteristics and data from 12 different rivers, including the MARGINS Waipaoa and Fly systems.
Subduction zone metamorphism
This module introduces students to subduction zone metamorphism through the examination of rock samples, calculating P-T-t paths, and comparing them to thermal model predictions of P-T paths.
Slab temperatures control melting in subduction zones, what controls slab temperature?
Hands-on demonstrations of advection and diffusion of heat in subduction zones, and their controls on slab thermal evolution and relationships to melting, using analog models.
