Geothermometers are natural mineral systems that may be used to estimate the temperatures that produce an equilibrated mineral assemblage in a metamorphic rock through element partitioning between minerals. This study is an experimental calibration of a garnet-biotite geothermometer using experimental methods based largely on Ferry and Spear's (1978) widely cited experimental calibration of a garnet-biotite geothermometer. This study used natural materials in order to better simulate metamorphic conditions. After a series of homogenization runs and experimental ion exchange runs at 600, 700 and 800°C this experiment has undergone entirely new reactions reflecting our simulated metamorphic conditions and resulting reactions of a pelitic amphibolite facies.
