- 1Geochemical AnalysisPurpose: To find an economic deposit of a mineral.
How: Collect and analyse water from a range of sites.
If deposit is present, water has permeated through and will pick up the mineral
The higher concentration is downstream the ore body. - 2Seismic SurveyPurpose: Exploration for oil such as hydrocarbon oil and gas
How: A ship toes a source of seismic waves that travel to the ocean floor through rocks and get reflected where a change of density is.
This detects change in rock type and reflected waves travel back to the ocean floor to the receivers on the cable.
- 3Magnetic SurveyPurpose: To detect anomalies in Earth's magnetism.
How: Flights over the area detect magnetic anomalies and are downloaded where software highlights these areas.
These could be metallic minerals or igneous bodies etc.
- 4Drilling BoreholesPurpose: To confirm presence of rocks.
How: A borehole is drilled into the ground (not too deep) and the core it produces is analysed.
Very expensive but most accurate.
