     In this paper, the authors apply biotite TAl geobarometer to calculate the emplacement depth of typical ore-forming porphyries in Geza magmatic belts in Indosinian and to estimate the crust uplift-denudation rates. The results indicate that the denudation rate of ore-bearing intrusion is rather slow with an average value of 0.018 mm/a, which is favorable to preserve the deposit after its formation. The study also provides a quantitative reference for the tectonic uplift and denudation of the western Yunnan plateau since Indosinian.
