- The project workspace was created by copying the latest version of the GB_3D project, dated 15th Sept 2011, (GB_3D_Completed_Sections_v30_GL_v7.gsipr). The faults and sections which lay out with the Great Glen — Moray Firth project area were stripped out. The GVS and GLEG were retained and a new DTM was created.
- Small edits were made to the faults before calculating the ‘fault network’.
- Existing GB_3D sections were correlated and new sections were drawn.
- Baselines were drawn for each geological unit based on the relevant geological map.
- Geological units were calculated.
- Numerous edits to sections were completed in an attempt to obtain fully calculated surfaces.
The fault network calculates correctly. However whilst the bedrock surfaces can be calculated to produce a surface (Figure 6), most surfaces have holes (uncalculated portions), Figure 7. The GSI3D software was under development for bedrock at the time of modelling. Subsequently the development was stopped and so the issue of holes within the calculated surfaces was not resolved. The model is therefore submitted to the National Geological Model as a ‘cross-section only’ project.
