The study or science of the measurements of formerr temperature of rock history: Geothermometry includes the direct or indirect measurement or approximation of the temperatures at which geologic processes take place or have taken place.

Geothermometry is the science of the Earth's heat and temperatures, and their effects on geologic processes.

Geothermometry pertains to the investigation of the Earth's heat and subsurface temperatures.

In geology class, Mary learned that geothermometry was important for determining a mineral or aggregate of minerals whose presence defined the temperature range of limits within which the minerals were formed, also known as a geologic thermometer.
