Information provided
Reconnaissance fieldwork can be used to familiarize the explorationist quickly with regional structural patterns, stratigraphy, and the distribution of rock types. It can also highlight areas where more detailed work is necessary. Existing maps should be spot-checked to determine if they can be confidently used for interpretation and as a base for additional work. In areas where geologic maps at the required scale are not available, detailed mapping and traversing may be required. Fieldwork can also be targeted to investigate specific topics such as fracture morphology and distribution, detailed fold geometry, and timing of structures.
The various types of fieldwork include the following:
- Regional reconnaissance
- Spot checks of existing maps
- Detailed mapping, traversing
- Targeted studies
When to use it
Structural fieldwork can be useful throughout an exploration program. If it is done prior to or in conjunction with the interpretation of seismic data in the area, it can help guide the interpretation. Structural fieldwork is most effective when done in conjunction with other stratigraphic and petrologic studies.
