The collisional orogenesis between north and south China blocks and intra-continental deformation finally led to the formation of the multiple Dabie-Tanlu-Sulu orogen.
华北与扬子地块碰撞造山作用与陆内变形最终造就了大别—郯庐—苏鲁复合造山带。

The mineraliztion is later than the activity of the magmas. And the deposits are formed in early Yanshan epoch, just after the collision of the continents and the orogenesis.
综合矿床的成矿年龄和与其有空间关系的岩体的成岩年龄可以看出,成矿年龄不同程度地小于成岩年龄,表明矿床形成于燕山早期,稍滞后于造山带陆-陆碰撞和陆内造山作用。

Through investigation and analyses of sedimentary settings especially the provenience of sediments, the Sinian-Jurassic sedimentary strata exposed in the study area have been recognized as Sinian-Lower Triassic passive continental marginal sequences and the Middle Triassic-Middle Jurassic foreland basin sequences. And then, it is inferred that the collisional orogeny in the Dabieshan orogen took place in the Middle Triassic.
通过对那里沉积物形成环境,特别是物源区的分析研究,识别出震旦系至下三叠统被动陆缘沉积岩系和中三叠统至中侏罗统前陆盆地沉积岩系,据此推测大别造山带碰撞造山作用发生在中三叠世。

The age of MORB-type metabasic volcanic rocks is(1462± 28) Ma using the SHRIMP zircon U-Pb method.The presence of MORB and IAT assemblages suggests the existence of an ocean basin in Yunkai area,Guangxi,southwestern South China Block during Grenvillian.They probably defined as a part of archipelagic ocean system before South China has formed unified Rodinia during the Grenvillian orogeny.Cathaysia block and Yangtze block have experienced continent-continent collision orogenics behind this ocean basin subducted,and have formed unified Rodinia.
MORB和 IAT组合的出现说明位于华南板块西南端的广西云开地区在 Grenville期可能存在过洋盆,它们很可能代表了 Grenville期造山作用形成统一的 Rodinia超级大陆以前的一个&多岛洋盆&系统,华夏古陆和扬子板块可能在该古洋盆于新元古代早期发生的全球性 Grenville期造山运动而发生消减消失后才开始碰撞和造山,形成统一的 Rodinia超级大陆。

By analysing the molasse sediment, tectonic stress field, thrust fault system and comparing them with volcanic rocks and granites in the region, it is showed that Dabie orogenic belt had a strong intracontinental orogenesis whose deep dynamic processes were controlled by subduction with delamination during late stage of Cretaceous period-late Cretaceous period.
磨拉石沉积、构造应力场、逆冲断层系统和区域火山岩、花岗岩的综合分析表明,大别造山带早白垩世晚期—晚白垩世存在一次强烈的陆内造山作用,其深部动力学过程受控于拆沉中的俯冲作用。

From about 206 Ma there occurred arc-continent collision accompanied by compressional contraction and shearing deformation of the arc crust and development of syn-collision granites. In the late Yanshanian epoch (138-73 Ma) post-orogenic extension came into action and resulted in the generation of A-type granites. During the Himalayan (65-15 Ma) intra-continental orogenic movement a large-scale strike-slip thrusting induced the intrusion of granites and development of pull-apart basins.
据此,再造了造山带的形成过程与演化历史:印支期的大规模俯冲造山作用(238~210 Ma),形成义敦火山岩浆弧;大约自206 Ma始,发生弧-陆碰撞,伴随岛弧地壳挤压收缩和剪切变形,发育同碰撞花岗岩;进入燕山晚期(138~73 Ma),岛弧碰撞造山带发生造山后伸展作用,形成A型花岗岩带;喜马拉雅期发生陆内造山作用(65~15 Ma),岛弧碰撞造山带出现逆冲-推覆和大规模走滑平移,伴随喜马拉雅期花岗岩的侵位和拉分盆地的形成。

The data show the following ages: 1894±17 Ma and 1847±59 Ma for garnet pyroxenite of the Tiantangshan Group complex, indicating a Paleoproterozoic age; 1462±28 Ma for the metabasic volcanic rocks of the Yunkai Group complex, indicating the presence of fragments of the Meso- and Neoproterozoic oceanic crust in the Yunkai area; 906±24 Ma for the granitic gneiss intrusion is, which should be the product of the global Grenville collisional orogeny occurring around 1000 Ma BP. In addition, an inherited detrital zircon age of 2702±13 Ma was also obtained, which is the oldest age in the Yunkai area and even in Cathaysia, proving the presence of Neoarchean continental crustal material in Cathaysia.
获得天堂山岩群石榴辉石岩的形成年龄为1894Ma±17Ma和1847Ma±59Ma,表明其时代为古元古代;云开岩群洋中脊型变质基性火山岩的喷发年龄为1462Ma±28Ma,证明该地区存在中元古代的古洋壳残片;获得花岗质片麻岩的侵入年龄为906Ma±24Ma,应为1000Ma前后发生的全球性Grenville期造山作用的产物,并获得2702Ma±13Ma的继承碎屑锆石年龄,这是云开地区乃至华夏古陆目前获得的最古老年龄,证明华夏古陆曾存在新太古代陆壳物质。
