ARGIN: 0cm 0cm 0pt; mso-pagination: widow-orphan" class=MsoNormal>ang=EN-US>Apatite Fission Track (AFT) data of the Micangshan-Hannan Dome region is reported in this work. It is shown that AFT ages decrease gradually from the inner part of the Micangshan-Hannan Dome to amespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />ace w:st="on">aceName w:st="on">NorthaceName> aceName w:st="on">SichuanaceName> aceType w:st="on">BasinaceType>ace>, which is consistent with the piggyback propagation model of thrusting in the region proposed by previous works based on seismic survey profiles. Thermal history modeling of the AFT data shows that the Micangshan-Hannan Dome experienced two episodes of rapid cooling occurred in Cretaceous (before ~90Ma) and Late Cenozoic (since about 15 Ma) respectively. amespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
