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 to construct the modelled surfaces are listed in the Weald Report (Chadwick et al., 1983[1]). No extra boreholes were used and the surfaces described in this report are based on structural contour data from the report.
Map data
The map data were generated directly from the Weald Report (Chadwick et al., 1983[1]) and cross-referenced with DigMap GB 1:250 000.
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 Weald Report (Chadwick et al., 1983[1]).
Geophysical data
Please see Chadwick et al (1983)[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:
- 1 – Base Tertiary
- 2 – Base Lower Greensand
- 03 – Top Corallian
- 4 – Top Cornbrash
- 5 – Top Penarth Group
- 6 – Top Variscan Basement
Pointset — GOCAD® project
- Contains all of the structural contours, derived from the modelled surfaces, as points (e.g. 01_Weald_Base_Tertiary_Structural_Contour_Points_vs)
Group — GOCAD® project
- EastMidlands_faults – contains all of the fault surfaces generated through the Structural Modelling workflow (e.g. weald_WLDF_001_ts).
- EastMidlands_Raw_faults – contains the “grouped” fault data used for fault surface creation.
- EastMidlands_Raw_Data – contains the contour and crop data used for surface modelling, borehole data points, 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_Weald_Base_Tertiary_ts)
- Other datasets include the DTM derived from the CEH DTM at 200 m resolution
