Early Military Geology (Structures)
- 5 Main Warfare Categories
- Tactical & Strategic terrain analysis
- Fortifications and Tunnelling
- Resource Aquisition
- Defence installations
- Field Construction & logistics
- Tactical & Strategic terrain analysis
- Fortification Construction
- Reasons
- Strategic Purpose
- Control/protect borders
- Protect comms. eg- Rivers
- Dominate Region
- Use as an army base
- Control/protect borders
- Defensibility
- Enhancing Natural obsticles
- Enhancing Natural obsticles
- Security
- No higher ground & good visibility
- No higher ground & good visibility
- Accessibility
- Escape Route
- Onsite water supply (wells)
- Escape Route
- Available construction materials
- Firm Foundations
- Well drained
- Strategic Purpose
- Ideal site:
- Isolated Rock Hillock
- 100-300m diameter
- Along navigable harbour
- -Igneous
intrusion,
resistant outcrop
strata,
lithological
changes,
structural
fearure
(fold/fault),
erosion can
enhance the
afformentioned
- Isolated Rock Hillock
- UK Castles
- Scottish Castles
- Edinburgh
- Igneous Strata
- Carboniferous
Volcanic plug, soft
materials
surrounding
- Accentuated by
glacial erosion
leaving sloping tail
- 27.4m deep well
- David's tower

- harlech
- built on an
anticline
known as the
harlech dome
- Caledonian Orogeny
- Greywackes
- Area where the
castle is built is
free of boulder
clay
- Caledonian Orogeny
- built on an
anticline
known as the
harlech dome
- Windsor
- built on Upper chalk anticline
- Surrounded by
london clay
- Thames erosion
caused castle to
be 30m high

london clay
- 3 wells 50m deep
- built on Upper chalk anticline
- Corfe
- Chalk monocline
- River N, W & S
- Chalk monocline
- Beeston
- Scottish Castles
- Summary
- Took advantage of local geology/topography
- Engineering extending natural features
- used access & comm routes effectively
- reliable water supplies
- Took advantage of local geology/topography
