Active Tectonics Field Trip part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
George Davis, University of Arizona
By far most field trips in structural geology and regional tectonics do NOT take place in large urban centers with a trip focus on mitigation of hazards. What is described here is an example of the instructional ...

Measuring the vertical gradient of gravity part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
Rob Sternberg, Franklin and Marshall College
The free-air effect tells us that as elevation above sea level increases, gravitational acceleration g decreases at the rate of about 0.3086 mgal/meter. This effect is routinely corrected for when making gravity ...

Skill puzzles part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
Sarah Titus, Carleton College
These are short exercises that allow students practice with concepts in Structural Geology, Tectonics, or Geophysics. (Many of them were designed with Eric Horsman.) The basic idea is to give students opportunities ...

New Views of an Old Continent: A Tectonics Lab Exercise Using Geophysical Maps of Australia part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
David Greene, Denison University
In this lab activity students are given five different map views of the continent of Australia: Geology, Gravity Anomaly, Magnetic Anomaly, Digital Elevation, and Satellite Image, and asked to investigate and ...

Taking the Pulse of Yellowstone's "Breathing" Volcano part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
Beth Pratt-Sitaula, Central Washington University
In this activity, students learn about volcanism in Yellowstone National Park, focusing on its history of eruption, recent seismicity, hydrothermal events, and ground deformation. They learn how scientists monitor ...

The science behind Plate Tectonics part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
John Weber, Grand Valley State University
Plate tectonics is a quantitative, robust and testable, geologic model describing the surface motions of Earth's outer skin. It is based on real data and assumptions, and built using the scientific method. New ...

El-Dab'a ground water aquifer assessment, Egypt part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
elhamy Tarabees, Damanhour University
El-Dabaa area is an area located in the norther part of the western desert, Egypt and planed to be nuclear power point. Some vertical electrical sounding have been done there to evaluate the ground water aquifer ...

Hydrocarbon Exploration part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
elhamy Tarabees, Damanhour University
To detect the hydrocarbon reservoir, structure traps should be detected. Seismic reflection profiles can be used to illustrate the structure image for the subsurface layers and hence, find out structure traps for ...
