OR/14/024 Model datasets
| TERRINGTON R L, WILLIAMSON J P. 2014. Metadata report for the Craven Basin 1:250 000 resolution geological model. British Geological Survey Internal Report, OR/14/024. |
DTM
Used as a reference dataset. The DTM source was NextMap at a 250 m cell/mesh size resolution.
Rockhead Elevation Model
BGS RHEM onshore was used, on which the entire outcrop for each of the surfaces generated in the project was draped. The resolution of the RHEM was 500 m cell size.
Borehole data
Boreholes used to construct the modelled surfaces are listed in the Northumberland-Solway basin subsurface memoir (Kirby et al., 2000[1]). The surfaces described in this report are based on structural contour data from the memoir.
Map data
The map data were generated directly from the Subsurface Memoir (Kirby et al., 2000[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 Subsurface Memoir (Kirby et al., 2000[1]).
Geophysical data
Please see details in the Subsurface Memoir (Kirby et al., 2000[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 its stratigraphic position and a CRVN addition to identify it’s origin from the Craven Basin model:
- 01 – Base Permo-Trias_CRVN
- 02 – Base Westphalian_CRVN
- 03 – Base Namurian_CRVN
- 04 – Base Chatburn_CRVN
- 05 – Base Dinantian_CRVN
Pointset – GOCAD® project
- Contains all of the structural contours as points (e.g. 02_Base_Westphalian_Structural_Contour_Points_CRVN_vs)
Group - GOCAD® project
Group names in GOCAD® project on the left, description on the right.
- 01_Base_Permian_Triassic_Faults_Traces_pl — Fault traces (Z attributed from the Base Permian-Triassic surface)
- 02_Base_Westphalian_Fault_Traces_pl — Fault traces (Z attributed from the Base Westphalian surface)
- 03_Base_Namurian_Fault_Traces_pl — Fault traces (Z attributed from the Base Namurian surface)
- 04_Base_Chatburn_Fault_Traces_pl — Fault traces (Z attributed from the Base Chatburn surface)
- 05_Base_Dinantian_Fault_Traces_pl — Fault traces (Z attributed from the Base Dinantian surface)
- 3DFaults — All faults grouped
- Fault_Centerlines_pl — Fault traces associated with a single horizon
- Fault_Outlines_Borders_pl — Outline border of faults
- Fault_Point_Sets_vs — Point cloud of fault geometries
- Fault_Traces_Joins_pl — Two or more fault traces correlating spatially between horizons
- Faults_Structural_Modeller_ts — Faults with no CRVNF identifier but outputted from the structural modelling workflow as a fault surface
- OLD_Duplicate_Faults_ts — Duplicate faults
- Old_Surfaces_ts — Old or component surfaces
- Outlier_Inlier_Outcrop_Curves_pl — Outcrop polygons of the model horizons
- Structural_Contour_Point_Parts_vs — Structural contour point parts.
Surface - GOCAD® project
- Contains those surface horizons that have been clipped to the combined outcrop and subcrop for that horizon (02_Base_Westphalian_Combined_CRVN_ts)
- Contains all of the fault surfaces generated through the Structural Modelling workflow with the CRVN indicating it is from the Craven Basin Model, the F identifying it as a fault object and the number relating to a unique identifier (e.g. CRVNF_2019_ts)
