Profiling Earth's Surface using GeoMapApp
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.
Sediment Dispersal and Continental Margin Stratigraphy
This module examines different sediment dispersal systems and their relationships and controls on margin stratigraphy and geometry, using data sets from the Fly and Waipaoa river systems.
Holocene Optimum: A time of massively increased sediment discharge for Asian Rivers
This is one component of the Source to Sink Mini Lesson Set This module is part of a larger set of mini-lessons that explores the variations in water and particulate mass flux from rivers that result from changing ...
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.
Accretionary vs. erosive subduction margins
This module examines the nature and variability of subduction margins through examination of data sets that document subduction zone inputs, deformation, and resulting morphology in different settings.
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.
The spectrum of fault slip
Introduction to the different types of slip behaviors that can occur on subduction thrust, and comparative analysis of data sets derived from earthquakes and slow slip events to learn to discriminate among events.
Central American Arc Volcanoes, Petrology, and Geochemistry
This module teaches basic concepts in igneous petrology through relating hand specimen identification of lavas to major element geochemistry, using the Central American volcanic arc as an example.
Role of Sedimentation in Rifting
A module in which students use field and geophysical measurements and observations of Gulf of California basins to calculate isostasy and its controls.
