摘要：以“螺旋”①学说为指导对山东大地构造背景进行了系统划分,为研究山东省构造演化和成矿规律奠定了基础。山东地处扬子陆块北东缘与华北陆块东缘接触部位,经历了太古代—中新生代多期构造旋回,随着中新生代Pangaea超大陆演化旋回和东亚螺旋作用,产生了扬子陆块与华北陆块的拼合,沿威海—日照—临沭对应的苏鲁高压—超高压变质带、胶辽隆起区的鲁东以NNE—NE向为主的构造体系;往西为沂沭(郯庐)滑动断裂与鲁西的阻挡,产生了鲁西的隆起和NNW—NW向构造体系,以及鲁西南—鲁西北的华北坳陷区;对应的中新生代沉积、构造与岩浆等作用,覆盖或改造—叠加了前期构造形迹,以济宁—聊城—广饶一线和沂沭断裂为界,划分为华北、鲁西与鲁东三个构造单元,分布范围大致为“3:4:3”;造就了山东特有的“343”式和以沂沭断裂的“丫”字形构造:NW—NNW—NNE—NE构造体系,成为中国大陆较典型区域性的螺旋构造系列,对研究国内及全球螺旋构造、成矿地质背景与圈定找矿远景具有重要借鉴意义。
In this paper,guided by the“spiral”①theory,the geological background of Shandong province has been systematically divided,which laid the foundation for the study of the geotectonic evolution and metallogenic regularity of Shandong.Shandong is located at the contact point between the north east margin of the Yangtze block and the east margin of the North China block.It has experienced multiple tectonic cycles from Archean to Mesozoic and Cenozoic.With the Mesozoic and Cenozoic Pangaea supercontinent evolution cycle and the action of East Asian spiral,the merging of Yangtze block and the North China block occurred,and a NNE-NE trending tectonic system was formed along the Weihai-Linshu high-pressure-ultrahigh pressure metamorphic complex belt and along the Jiao-Liao uplift area;to the west,the West Shandong uplift,NNW-NW trending tectonic system and the North China depression in southwestern—northwestern Shandong were formed by the transition of the Yishu(Tanlu)fault and the blocking of the West Shandong;The corresponding Meso-Cenozoic sedimentary,tectonic and magmatic processes overlaid or reformed-superimposed the previous tectonic features,forming the Jining-Liaocheng-Guangrao line and the Yishu fault as the boundary,which can be divided into three tectonic units:North China,West Shandong and East Shandong,and the distribution area is roughly“3:4:3”.The“343”type unique to Shandong and the“Y”-shaped structure of the Yishu fault:NW-NNW-NNE-NE structure system was created,which has become a typical regional spiral tectonics series in China's Mainland,and is of great referential significance for the study of domestic and global spiral tectonics.
