EG map versus geological map
Short answer
A geological map shows rock distribution, age, and structure for geologists, while an engineering geological map shows geology classifed by engineering behaviour (strength, weathering, permeability) for civil engineers, including soil, water, hazards, and suitability zoning, usually at larger scale.
Differentiate between engineering geological map and geological map.
| Point | Geological map | Engineering geological map |
|---|---|---|
| Purpose | Shows distribution of rocks, age and structure | Shows geology as it affects engineering works |
| Classification | By origin and age (stratigraphy) | By engineering behaviour (strength, weathering, permeability) |
| Content | Rock units, contacts, folds, faults | Also soil, groundwater, weathering, slope stability, hazards, borrow areas |
| Scale | Usually small to medium | Usually large scale for a site |
| Users | Geologists | Civil engineers and planners |
| Interpretation | Descriptive | Includes suitability zoning and recommendations |
