Exploration for oil is carried out by seismic surveys
GeoChemical Analysis
GeoChemical Analysis is a cheap easy way to find
a mineral vein. Sample water from a stream
network. Analyse the concentration of a mineral.
Closer to the vein, higher concentrations.
Magnetic Anomaly
Survey
Highlights areas with abnormal
magnetic fields = metalic
minerals, igeous bodies etc.
Borehole
Drilling
Drilling Bore Holes is expensive but does
give the best evidence of a reasource
being present
Used to confirm the
presence that a seismic
survey will suggest is there
