  1. OUTLINE 64: ANSWERS • What type of geological structures are represented • by the parallel linear ridges and valleys of the • northern Rockies? THRUST FAULTED BLOCKS • 2.Make a sketch of the geological relationships on • Yamnuska mountain, near Calgary. • 3. What is the direction of dip of the thrust faults on the eastern flanks of the Rockies? TO THE WEST

  2. OUTLINE 64: ANSWERS (cont.) • What was the direction of movement of the thrust faulted • blocks? TO THE EAST • 5. What was the ultimate cause of crustal compression? • PLATE TECTONICS – SUBDUCTION • What was the original width of the mountain belt calculated • to before compression? 300 KM • 7. What is the present width of the mountain belt? • 140 KM • What is the rate (mm/year) at which the crust has been • compressed? • 160 KM IN 160 MILLION YEARS • = 160 x 103 x 103 mm/ 160 x 106 yrs = 1 mm/yr
