摘要: Abstract The Qulong and Xiongcun porphyry deposits in the Gangdese Copper (Molybdenum) Metallogenic Belt (GCMB) are both giant deposits. They were located eastern central GCMB (about 400 km apart), generated Miocene Jurassic, respectively. In order to reveal why two asynchronous could occur same metallogenic belt, in-situ zircon U-Pb, apatite fission track (ZFT AFT), (U-Th)/He (AHe) dating conducted. Their associated exhumation amounts histories compared, finally prospecting significance was evaluated. AHe ages of deposit indicate it underwent an amount at least 1.3–2.8 km since 13.8–13.1 Ma. However, AFT data modeling results that experienced stages rapid cooling 20–13 Ma 13–8 Ma, temperature decreases from 160 °C 40 °C after ∼20 Ma corresponding is about 4–6 km. Integrated regional thermochronological data, 4–6 km
