Mineral Exploitation - current survey techniques Flashcards
1
Q
What is the process of IR Spectroscopy
A
- Different minerals emit IR radiation at
different wavelengths
-The different wavelengths can then be
used to identify the minerals
2
Q
What is IR Spectroscopy used for
A
Used to identify minerals
3
Q
What is the process of Gravimetry
A
Gravimeters detect variations in gravity caused by variations in density and total mass below the instrument (gravimeter)
4
Q
What is Gravimetry used for
A
Used to detect variations of gravity caused by variations in density and mass. Igneous rocks are usually more dense than sedimentary deposits
5
Q
What is Magnetometry
A
Magnetometers detect rocks that are more magnetic such as the iron ore, magnetite and ores of cobalt.
6
Q
What is Magnetometry used for
A
Magnotometers are used to detect rocks that may be magnetic
