Question 2

Discuss how geologists identify new mineral deposits.

Accepted Answer

Aerial or satellite photography can be used to identify geologic formations that may contain certain types of mineral deposits. Aircraft and satellite instruments can also measure Earth's magnetic gravity fields to reveal other deposits. Seismographs, used to detect earthquakes, can also provide clues about mineral deposits. In the sea, depth-measuring devices are used to produce detailed three-dimensional maps of the sea floor, which can be analyzed to reveal probable mineral deposits. Once the site of a possible mineral deposit is identified, mining companies will drill or tunnel for mineral samples and analyze their composition.
