Software used
- GOCAD® version 2.1.6 and GOCAD® v2009
- ArcGIS 9.3
- MS Excel
Model workflow
The following workflow was used to generate the Northumberland-Solway Basin Model:
- Compiled all raw data into a GIS
- Imported all fault traces, outcrop data and structural contours for each horizon into GOCAD® version 2009 onwards.
- Additional data added included the GB RHEM and the NextMap DTM surfaces (See Model Datasets)
- A raw surface (uncut by faults at this stage) for each horizon was modelled using a combination of the structural contours and outcrop which had elevation values applied from the RHEM surface data.
- Every fault trace was draped onto its corresponding surface using the ‘Transfer Property by Vertical Projection’ tool and then following the methodology established in Modelled Faults, the fault plane was constructed.
- Once all of the faults had been constructed, branch contacts were established between the faults using the Structural Modelling workflow.
- The faults were then used to cut the raw surface horizons using the ‘Horizon-Fault Contact Modelling’ in the Structural Modelling workflow.
- Fault contacts and surface horizons were either edited using the Structural Modelling workflow parameters or manually using the tools available in GOCAD®
