In addition, the exchange of oxygen isotopes between coexisting minerals during cooling was examined. The mineral pair with the largest isotopic fractionation (PLIF) can bracket their apparent equilibrium temperature (T ae) within their Dodson closure temperatures. This special feature of PLIF may be used to constrain the thermal history of slowly cooled plutonic and metamorphic rocks.... programmed with a Eurotherm controller so that it took only -24 s from the relaxation temperature (200AdC) to the target ... low temperature runs (407-609AdC) were relatively long (agt;24 hours), manual heating was applied and it took -1 minuteanbsp;...
