In this paper, we report the application of the modified two-feldspar geothermometer to granulite-facies rocks from two known UHT localities (Dongpo and Dajing/Tuguiwula) and two other localities in adjacent areas (Tuguishan and Xuwujia). WebA new approach to reconstruct the temporal variation of rock surface temperature using the TL of feldspar is introduced. Forward modelling of different TL signals suggests that TL signals in the range of 210 to 250 ∘C are sensitive to typical surface temperature fluctuations, which we define as TL thermometers. mouse y cursor
