| 英文摘要 | Pressure and temperature (P-T) conditions of the crystallization of the Mesozoic (similar to 130Ma) Guojialing granodiorites from the Jiaodong Peninsula (eastern China) have been investigated based on hornblende geothermobarometry and fluid inclusions. The calculated P-T conditions are, 694 similar to 733 degrees C and 1.3 similar to 2.4kbar, 702 similar to 719 degrees C and 2.4 similar to 3.9kbar, and 723 similar to 727 degrees C and 3.8 similar to 4.2kbar for the Guojialing, Congjia and Beijie plutons, respectively. There are 5 types of primary fluid inclusions, most of which belong to the CO(2)-H(2)O-NaCl type, in the quartz of the granodiorites. The P-T conditions measured for homogenization temperature and salinity of the primary CO(2)-H(2)O-NaCl inclusions are in agreement with that obtained from the hornblende geothermobarometry. It is concluded that the emplacement depths are 6km, 10km and 13km for the Guojialing, Congjia and Beijie plutons, respectively, from east to west. This 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 the Early Cretaceous. |
