Description:

Before class, students complete a homework assignment that familiarizes them with accessing and downloading Mars THEMIS images and in which they download images of normal faults in the Ceraunius Fossae of northern Tharsis. In class, I start with a short discussion about how THEMIS images are obtained, why the images are in strips, what resolution means, and so on. Students then examine their Mars images and identify normal fault features. Students determine the range of graben widths and then calculate throw for one fault using shadow width to calculate graben depth. Students then calculate heave for the same fault, assuming a fault dip of 60Â. Students then do a back-of-the-envelope calculate to estimate crustal extension along a line across several graben. Students finish the activity by considering the impact of their assumptions on their results and evaluate the validity of their back-of-the-envelope calculation of extension. At the very end, we look at research results from several studies that have carefully calculated extension in Ceraunius Fossae.
