1·Before Later Proterozoic era, in this area more than two times of thermodynamic metamorphism took place.
在晚元古代以前该地区至少发生过两次热动力变质作用。
2·The data offered here favor that the collision between the Yangtze and Cathysia blocks happened in the late Proterozoic era.
现有资料支持华夏和扬子两地块在晚元古代碰撞拼合的解释。
3·This splitting and collision zone is formed in the Process of splitting and closing of Huaxia massif in the late Proterozoic era.
该裂碰带是在新晚元古代以后，华夏地块发生裂解、闭合过程中形成的，是使本区前寒武系地层产生变质、混合岩化和花岗岩化的主导因素。
4·The Shengong Movement in late Middle Proterozoic Era was strong and the superimposed fold of Junning Movement in late Qingbaikou Period was clear.
中元古代末的神功运动表现强烈， 青白口纪末的晋宁运动叠加褶皱明显。
5·Therefore, based on its isotopic characters, the "dolomitic marble" is more likely of volcanic carbonatite rock formed during middle Proterozoic era.
由此看来，“白云质大理岩”很可能是中元古代碳酸岩火山岩。
6·The data mentioned above lead to suggest that the granulites are the representatives of middle to lower crust formed round about late Proterozoic era.
上述资料表明本区的麻粒岩是形成于晚元古代前后的中下地壳产物。
7·Due to inherited effect of the positive shear stress of proterozoic era, the main shear zone which ran parallel to rift greenstone belt and its gold deposits came into being.
元古宙正剪切应力继承作用，产生了与裂谷型绿岩带平行的主剪切带及其金矿。
8·This leads to the authors'conclusion that the proterozoic era is most likely the high time for the formation of sedimentation deposit of magnesianite. This also explains the basic global g…
同时，相应解释了在地质史中，自元古代以来，富镁碳酸盐沉积逐渐变少、而富钙碳酸盐沉积逐渐变多这样一个全球性的基本地质事实。
9·The studies of microelement, rare earth element and isotope compositions that the Huogeqi polymetallic ore field was formed in rift basin of back arc continental marging during Proterozoic Era.
从微量元素、稀土元素、同位素等方面论证了霍各乞矿田中元古宙为大陆边缘弧后裂谷盆地构造环境。
