Geology applications of Fourier transform infrared spectroscopy

Fourier Transform Infrared Spectroscopy (FTIR) is a way to measure the energy that is emitted from objects as light. Geologists use FTIR to measure the light given off by certain rocks and minerals. By looking at the light given off, geologists can learn about the history of the rocks and minerals and find out more information about their chemical structure. For example, FTIR can be used to tell if a rock is made of granite or marble, or to tell what elements are in the rocks and minerals, like if they contain water or carbon.
