Digital Terrain Model (DTM)
Used as a reference dataset. The DTM source was NextMap at a 200 m cell size resolution. A surface was then created from extracted points. Optimisation was performed to produce more triangles in areas of more detail.
Borehole data
Boreholes used in the model have been extracted from the Stratigraphic Surfaces database. The surfaces described in this report are based on structural contour data from the memoir; they are warped to fit with the borehole data in the latter stages of the modelling process.
Map data
The map data were generated directly from the Subsurface Memoir (Smith et al., 2005[1]) and cross-referenced with DigMap GB 1:50 000.
Mine plan data
No mine plan data were used.
Seismic data
Seismic data were interpreted and used in the generation of the contour data in the Subsurface Memoir (Smith et al., 2005[1]).
Geophysical data
Please see Smith et al (2005)[1]
GOCAD® objects
The following objects relate to the project specific data types within the GOCAD® project file. Each of the horizon datasets will have a pre-cursor number to identify it using the schema:
- 01 – Variscan Unconformity
- 02 – Base Warwickshire Group
- 03 – Top Namurian
- 4 – Top Dinantian
- 5 – Caledonian Unconformity
Pointset — GOCAD® project
- Contains all of the structural contours, derived from the modelled surfaces, as points (e.g. 01_SW_Pennines_Variscan_Unconformity_Structure_Contour_points.vs)
Group — GOCAD® project
- SW_Pennines_boreholes – data extracted from the SSD and used for surface fitting.
- SW_Pennines_faults – contains all of the fault surfaces generated through the Structural Modelling workflow (e.g. SWPennines_SWPF001N_ts).
- SW_Pennines_Raw_faults – contains the 'grouped' fault data used for fault surface creation.
- SW_Pennines_Raw_Data – contains the contour and crop data used for surface modelling and the 'pre-grouped' fault cut data used for fault modelling
Surface — GOCAD® project
- Contains those surface horizons that have been clipped to the combined outcrop and subcrop for that horizon (01_ SW_Pennines_Variscan_Unconformity_ts)
- Other datasets include the DTM derived from the NextMap DTM at 200 m resolution
