Pressure-Temperature (P-T) conditions

Pressure-Temperature (P-T) conditions refer to the specific combination of pressure and temperature experienced by rocks inside the Earth. These conditions influence how rocks behave and transform, such as melting, metamorphosis, or mineral changes. Higher pressure and temperature can cause minerals to recrystallize or change form, shaping the Earth's crust over geological time. Understanding P-T conditions helps geologists determine the history and movement of Earth's materials, as well as locate natural resources like minerals and hydrocarbons. Essentially, P-T conditions are key to understanding the physical state and evolution of rocks deep within our planet.
