Study on exhumation/uplifting of the Mengshan Mountain since the Late Cretaceous is important for the comprehensive understanding of tectonic evolution of the Western Shandong Rise. Six adamellite samples from the Mengshan Mountain were systematically collected to carry out apatite/zircon fission track dating and timetemperature thermal history modeling. The results indicate that the Mengshan Mountain experienced a relatively rapid exhumation/uplifting since the Late Cretaceous. Two rapid upliftings occurred during 70~43 Ma and 32~20 Ma with an accelerated process. The rapid uplifting events of the Menshan Mountain since the Late Cretaceous were slightly earlier than that of the Taishan Mountain (northern Mengshan Mountain)and coupled well with it on the whole.The uplifting polarity of the Western Shandong Rise was formed from south to north considering its halfgraben structural style. The two uplifting periods of the Mengshan Mountain were consistent with two distinct subsidence/cooling processes occurred in the Jiyang Depression adjacent to the Western Shandong Rise. There is a good uplifting/subsiding coupling relationship between the rapid uplifting of the Mengshan Mountain and the subsidence of the Jiyang Depression.
