Below is a description of a series of geologic events. On the worksheet (I-5), sketch a block that could represent this description. We have an important suggestion: draw a rough draft on your own scratch paper first. |
1. Layers were deposited. 2. The block was then offset by a vertical dip-slip fault such that the back half of the block was pushed up. 3. These faulted layers were then intruded by a dike, and the uplifted block was eroded down to the level of the other block.
