【摘要】 通过对千里岩隆起及邻区重磁资料、周缘断裂特征、过千里岩隆起地震剖面、苏鲁造山带及千里岩岛岩性、地层年代学、古地磁、中国大陆科学钻探钻孔等资料的收集整理,总结了该区重磁、周缘断裂及苏鲁超高压变质带等方面的最新研究成果,探讨了千里岩隆起在海区可能的延伸情况。研究认为千里岩隆起为印支期华北-扬子板块俯冲碰撞陆壳回返的产物,是苏鲁超高压变质带在海域的延伸,其南部边界断层为千里岩南缘断裂,北部边界可能为青岛-荣成断层在海区的延伸部分,东侧可能终结于黄海东缘断裂。在印支期后千里岩隆起遭受剥蚀,并受早白垩纪花岗岩侵位,千里岩南缘断裂在晚白垩世反转成为正断层,控制了南黄海盆地北部坳陷新生代沉积。更多还原

【Abstract】 Based on the integration of gravity and magnetic anomaly data,fault characteristics,seismic profiles,petrology,stratigraphic chronology and paleomagnetic data as well as the data from the Chinese Continental Scientific Drilling program,this paper summarized the latest research achievements in the Qianliyan uplift and adjacent area.The character of the gravity and magnetic anomaly field,the faults distribution pattern in this area,and the Sulu HP-UHP metamorphism terrane and its extension into the middle of South Yellow Sea were discussed.The Qianliyan uplift was resulted from the northward subduction of the Yangtze plate beneath the Sino-Korean craton during the Indosinian,as part of Sulu HP-UHP metamorphism terrane.The Southern Qianliyan Fault is the boundary fault of the uplift in the south and the north margin of the uplift may be bounded by the extended part of the Qingdao-Rongcheng Fault in the Yellow Sea.And in the east,the uplift is probably ended at the East Marginal Fault of Yellow Sea.The Qianliyan uplift was eroded after the Indosinian,and intruded by granite during Early Cretaceous.The Southern Qianliyan Fault was reversed to a normal fault at Late Cretaceous.Cenozoic deposition of the Northern South Yellow Sea Basin was controlled by the fault.更多还原
