Thermal history refers to the study of past temperature changes in the Earth's crust and mantle, as well as the effects of these changes on the structure and properties of rocks and minerals. This research area aims to understand the tectonic and geologic processes that have influenced the thermal evolution of the Earth over millions of years. By analyzing the thermal histories of rocks, scientists can reconstruct the geological history of a region, determine the timing of events such as mountain building or volcanic activity, and better understand the mechanisms driving plate tectonics and Earth's overall heat budget. Thermal history research is crucial for reconstructing past environments, predicting future geological events, and understanding the dynamics of the Earth's interior.
