OR/15/035 Modelled faults

Thompson, J F. 2015. Model metadata report for HS2 Area 4. British Geological Survey Internal Report, OR/15/035.

Several small faults, most with throws of less than 10 m were modelled, dipping 65 degrees for drawing guidance, based on mapped surface faults. These were modelled using the superficial engine as steps in the geological surfaces rather than as a faulted bedrock model where the unit is in contact across the fault. No major faults occur in the modelled area.
