Question

Examine Figure 1.11. Note that all of the layers in this block diagram are com posed of sedimentary rock and the unconformities are colored in red. Using the geologic laws discussed earlier and following the examples shown in Figures 1.6 and 1.7, identify the geologic events that occurred in this area. Then place the fol- lowing geologic events in the correct relative time sequence. Figure 1.11 | Block diagram to use to answer questions 7, 8, and 9.

Explanation / Answer

By careful observation of the given map, the geological events are as follows:

1. Submergence and deposition of sediment layer 1-6

2. Tilting

3. Uplift and erosion (angular unconformity)

4. Submergence and deposition of sediment layer 7-9

5. Fault

6. Uplift and erosion ( disconfomity)

7. Submergence and deposition of layers (10-13)

8. Uplift and erosion to current position

1-oldest, 8-youngest
