摘要
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.
