摘要
Pressure and temperature (P-T) conditions of the crystallization of the Mesozoic (~130 Ma) Guojialing granodiorites from the Jiaodong Peninsula (eastern China) have been investigated based on hornblende geothermobarometry and fluid inclusions. It is concluded that the emplacement depths are 6 km,10 km and 13 km for the Guojialing, Congjia and Beijie plutons, respectively, from east to west. It indicates that the denudation thickness for the western pluton is much bigger than that for the eastern one, and therefore the exhumation rates were probably not uniform within the Jiaodong Peninsula since Early Cretaceous.
