3D Geological Mapping (Modelling) in
GSOS worldwide & the BGS National
Geological Model of the UK.
Steve Mathers, British Geological Survey
Outcome from Portland 09 workshop
• Illinois State-BGS publication summarising the
state of geological modelling -3D mapping in
GSO’s worldwide (mainly those at Portland)
• 6 federal – national surveys and many stateprovincial surveys contributed
• Profiles of modelling in these surveys plus
uncertainty, property modelling, review of
available softwares and delivery mechanisms
• Its early days still with all this, gives advice for
newcomers

Hard copies
Thanks to Dick(y) and Cheryl
at ISGS for hard work on
production and copy editing from
co-editors and contributors
39 authors from 14 entities
The 3-D modeling and visualization software programs used by the USGS
(Jacobsen et al.).

Applications
•
•
•
•
•
•
•
•
•
Water
Waste management & contamination
Hydrocarbon resources and CCS
Land use planning, linear routes
Civil Engineering
Archaeology
Minerals
Geohazards
Research Education and Outreach
Many Framework models (3D maps) are fit for any purpose
Conclusions
•
•
•
•
•
•
•
Benefit from shared experience of use and evaluation of software and methodologies and
workflows for use in GSOs
Comparison of data management and storage, linkage to native data
Share experience of model use and clients and effective means of delivery
Encourage more model publication on the web
Maintain the momentum of the established network (today etc)
Discuss future interoperability and standards to enable exchange, trans boundary fusion etc.
Move towards 3 Geology? (long term aim need to the models first)
Suggestion
• Field guide to modelling systems? What to use where when at what resolution with what
sorts of data to give what sorts of outputs
BGS National Geological Model
Existing - legacy models
1995-2010
A jumble of lego and duplo
bricks (not voxelated though)
We need the instructions
to build the castle
Contour maps
Subcrop maps
And in addition
Regional geophysical compilations
Sections (drawn to scale)
Seismic lines (depth converted)
Edinburgh
Belfast
SW England – Wales
Regional sections
Crustal Scale Model
GSI-GSNI-BGS
UK 3D Bedrock model
• Initial build was for the EA (England & Wales)
• Down to 2-3Km at Group level (plus)
• Use for national and regional assessments for
Groundwater, Radwaste storage, Geothermal,
CCS…
• Outreach (radwaste Cumbria)
• Geoscience Education (hope for free download)
• Tectonic Evolution & Structure
Progress
•UK3D almost completed for Wales and good
progress in Scotland, stratigraphic checking
underway
•Attribution-Parameterization team set up
Parameterisation
•Aquifer type and flow style
•Engineering Props
•Geohazards
•Mineral potential
•Hydrocarbon importance
EA Aquifer classification of initial fence diagram
Detailed fence diagram for SE England can be calculated in GSI3D
•
Calculated Volumes down to Lower Cretaceous
including Grey and White Chalk aquifers
Thames Basin hydro modelling
Multi-scaled pilots London and Moray
Nesting stratigraphies, compromises will be necessary
Easiest to do for Stratified rocks – stratigraphers permitting
Deconstruction to Geological Object Store then available
for editing and reconstruction into new generation models
