Homework 2 Spencer: Exercises 7-3; 8-1; 8-2 For each topographic map predict the outcrop of a thin bed (i.e. it appears as a single line on the map) which occurs at A. In each map the bed has a different dip. On map (a) the dip is 11° north- wards, on map (b) the dip is 11° southwards, in (c) A N 15 30 45 60 15 30 45 500m 60 120 106 90 75 120 105 90 75 the dip is vertical and the strike is east-west, and in (d) the dip is 3.4° southwards.
