Ways of Finding Resources

Question	Answer
Geochemical Analysis Image: 17c8e86e-4bc7-4c40-bb35-d5f3da6afbf0 (image/jpg)	Purpose: 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.
Seismic Survey Image: d4367f39-c8af-429f-9186-f74ef94f8b19 (image/jpg)	Purpose: 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.
Magnetic Survey Image: 88b13d44-4dbe-413e-8e11-af4dc9ab2a13 (image/jpg)	Purpose: 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.
Drilling Boreholes Image: dcea3f5a-7c9b-4e61-b396-dc2971e78e88 (image/jpg)	Purpose: 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.
