What Can (and Cannot) Be Learned from Scientific Drilling Using Examples from Margins Initiatives part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This is a lecture segment that could be used in an introductory geoscience class to help explain and demonstrate what can be found out by scientific drilling. It should follow lectures on rocks, minerals, Earth's layers and simple plate tectonics, and be incorporated into a discussion of how we know what the Earth's interior is like. The lesson uses two examples from Margins Initiatives as problems that can be addressed successfully using scientific drilling: 1) the concept of reference sites for subduction factory inputs, and 2) understanding the mechanical behavior of sediments/rocks involved in seismogenic zone earthquakes. The lesson begins by pointing out that scientific drilling is NOT how we learn about the earth's deep interior, which is a common misconception among beginning students.
