ARGIN: 0cm 0cm 0pt" class=MsoNormal>ang=EN-US>K-feldspar MDD (Multiple Diffusion Domain) and fission track are two commonly-used methods in low closure temperature thermal chronometry. By modeling both the feldspar ³⁹Ar/⁴⁰Ar data and the fission track age and track-length data, the thermal history that sample underwent can be revealed and the effective temperature range of both feldspar ³⁹Ar/⁴⁰Ar method and fission track method is extended. Because of the multiple resolution of modeling, it is important to restrict the modeling process to gain a reasonable result, though it seems difficult. Three rapid cooling events, occurring at 130ascii-font-family: ’Times New Roman’; mso-hansi-font-family: ’Times New Roman’">～ang=EN-US>150 Ma, 30ascii-font-family: ’Times New Roman’; mso-hansi-font-family: ’Times New Roman’">～ang=EN-US>40 Ma and 5ascii-font-family: ’Times New Roman’; mso-hansi-font-family: ’Times New Roman’">～ang=EN-US>10 Ma respectively, in northern margin of Qaidam Basin are revealed by feldspar MDD method and fission track method.
