摘要
笔者根据鲁东地区发育的变质建造、古火山岩带、中新生代陆源建造、燕山褶皱幕活动,以及含金矿化建造特征等诸方面,建议以桃村—山相家断裂为界,将鲁东地区三级大地构造单元划分命名为: 胶南隆起:位于桃村—山相家断裂以东,响水口—千里岩深断裂带以西。含临沭断陷、即墨—桃村断陷、海阳凹陷、俚岛地堑。胶北隆起:位于桃树—山相家断裂以西,沂沭深断裂带以东。含诸城—五莲凹陷、胶州—莱西(平度)拗陷、黄县(现黄城)—龙口(现黄县)拗陷。
With reference to the metamorphic formations, the palaeovolcanic rock belts, the Mesozoicvand Cenozoic terrigenous formations, the folding activities of the Yanshanian phase, the characteristics of gold mineralization formations, etc., the author suggests that the third-order Jiaodong tectonic unit, taking the Taocun-Shanxiangjia fault as the boundary, be divided and named as:1)Jiaonan Uplift, which lies to the east of the Taocun-Shanxiangjia fault and west of the Xiangshuikou-Qianliyan deep fault belt and includes Linshu graben, Jimo graben, Jimo graben, Haiyang depression and Lidao graben, and2)Jiaobei Uplift, which lies to the west of the Taocun-Shanxiangjia fault and the east of the Yishui fault belt and includes Zhucheng-Wulian depression, Jiaozhou-Laixi (Pingdu) depression and Huangxian(i. e. Huangcheng at present)-Longkou(i, e. Huangxian at present)depression.
