Based on the terminology you've provided, we can infer some general geological principles. Here's a possible arrangement based on typical geological formations:
- Response area formed first: HLayer
- Response area formed more recently: GLayer
- Response area was the last to form: F
- Fault: (the fault would interact with the layers, typically indicating a disruption in the geological timeline).
Please verify how these layers and structures relate to your specific diagram for accuracy. Adjust if necessary based on the specific sequence observed in your diagram.
