Question

This model is slightly more complicated than the previous one. The geologic map is complete, but only two of the cross sections are available. Letters A -G are ages from oldest (A) to youngest (G). Finalize Cardboard Model 2 as billows. First, complete the north and east sides of the block. Notice that the rock units define a fold. This fold is an anticline, because the strata are convex upward and the oldest formation (A) is in the center (inside) of the fold. It is symmetric (non-plunging), because its axis is horizontal. (Refer back to FIGURE 10.8 for the differences between plunging and non plunging folds it you ate uncertain about this.) On the geologic map, draw strike and dip symbols to indicate the attitudes of formation E (gray formation) at points I, II, III, and IV. Also draw the proper symbol on the map (top of model) along the axis of the fold (refer to FIGURE 10.5). How do the strikes at all four locations compare with each other? How does the dip direction at points I and II compare with the dip direction at points III and IV? In your answer, include the dip direction at all four points.
