摘要
提出胶东—苏北构造带以广泛出露榴辉岩和超基性岩、普遍发育韧性剪切带和糜棱岩带为特征,具混杂岩特点。它经历了早元古代大陆推覆构造事件(2000~2400Ma)、早元古代末低角闪岩相变质热事件(1800~2000Ma)和元古代末大陆推覆构造事件(6O0~800Ma)。该构造带是华北陆块与华南陆块之间的过渡带。
The eastern Shandong-northern Jiangsu tectonic zone has the characteristics of wide-ranging emergence of eclogites and ultrabasic rocks,wide-spread growth of tenacity shearing zone and mylonite zones.It possesses the properties of mingle rocks.It underwent the continental napping event at the Suberthem(2000-2400Ma),the amphiboleface metamorphism event at the late Suberthem (1800-2000Ma) and the continental napping event at the late Proterozoic era(600-800Ma).This tectonic zone was a trantition zone between the northern China plate and the southern China plate.
