EAS 1700 Worksheet Y OUR N AME ……………………………………… S EDIMENTARY B ASINS AND THE L ITHOSPHERE 1 E XERCISE 1: E STIMATING THE L ITHOSPHERE S E LASTIC T HICKNESS (Two questions @ 5 points = 10 points) A. Using the Devonian stratigraphic columns, estimate the Catskill Foreland Basin’s half- width in degrees of longitude. B. Using your estimate, find the lithosphere’s elastic thickness from Equation 7. Please show your work. E XERCISE 2: S IZING U P C ONTINENTAL L ITHOSPHERE (Five questions @ 5 points = 25 points) A. How does the half-width the Appalachian Foreland Basin compare with the half-widths of foreland basins the world over? B. … with the radii of cratonic basins the world over? C. Realizing that some of the variation in foreland basins’ half-widths and cratonic basins’ radii is due to later geological developments 2 what do you estimate the typical range in continental lithosphere’s elastic thickness to be?
