Abstract

This article reports 21 AFT apatite fission track data from the West Shandong 山东 rise WSR and Jiyang 济阳 depression and mainly studies their Cenozoic uplifting/subsidence history and the relationship between them Furthermore we improve our insights into the Bohai Bay Basin BBB Our AFT analysis and AFT Tt modeling indicates that the WSR was uplifted at ca 65 Ma with apparent uplift rate of 0019 mm/a it underwent two relatively rapid uplifting events at 43–33 and 16–0 Ma with rates of 0097 and 0052 mm/a respectively Meanwhile the Jiyang depression subsided at rate of 0032 mm/a at 52–43 Ma and the rate increased to 013 mm/a at ca 42–33 Ma finally the subsidence rate increased to 0053 mm/a in 16–0 Ma They all underwent a uplift in time of 23–16 Ma with rate of 004–007 mm/a A careful comparison shows that the Cenozoic uplifting of the WSR coupled well with the subsidence of the Jiyang depression Our research also suggests that the upliftbasin coupling events are part of the couplings between the Bohai Bay Basin and its peripheral mountains This intraplate mountainbasin coupling is a reflection of global tectonic events
