There are four principal palaeogeographic units in the late sinian in the middle yangtze region , i . e . carbonate tidal flat , open carbonate platform , platform - margin slopes and a basin in the south 由于地壳差异性升降运动，晚震旦世陡山沱期岩相古地理格局发生了急剧变化。
On the basis of lithofacies palaeogeographic map , the sedimentary and lithofacies palaeogeographic characteristics of the middle yangtze region during the late sinian and early cambrian are also described 晚震旦世岩相古地理格局由碳酸盐台地（鄂中台地）和南边的台缘盆地组成。
Haoxi nb - ta mineral deposits in guangning county of guangdong province occurs in the c - formation of sinian system strata and the folding structures and faulted structures is a very development in the area 摘要广东广宁厚溪铌钽矿床赋存于震旦系c组地层中，区内褶皱构造、断裂构造十分发育。
As the founder of zhendan university , fudan university and furen university , maxiangbo has made great contribution to the progress of society as well as the development of education in china 马相伯是三所大学(震旦、复旦、辅仁)的创始人，为我国社会进步和教育事业的发展做出了巨大的贡献。
In the new plan , the position of the studied strata in the stratigraphic column of late precambrian of china shows an impotant relation between sinian system and qingbaikou system on the geologic and biologic evolution 新方案中这些地层在我国晚前寒武纪地层柱中的位置，反应出了震旦系与青白口系的地史演化及生物演化间的重要关系。
The ayadeng and sailinhudong formations were established in the 1970 ' s by the regional geological survey , and the former was considered to belong to the proterozoic baiyunebo group and the later belonged to the sinian system 摘要阿牙登组和腮林忽洞组是上世纪70年代1 / 20万区调建立的地层单位，当时将阿牙登组置于白云鄂博群，腮林忽洞组归于震旦系。
According to the type and scale of stratigraphic contact , four synthems such as basement ( pre - sinian ) , lower ( palaeozoic ) , middle ( mesozoic ) and upper ( cenozoic ) are divided , and seven sub - synthems are subdivided 本文依据地层接触关系的类型和规模，将本区划分为基岩(前震旦系) 、下(古生界) 、中(中生界) 、上(新生界)四个构造层和内部的七个构造亚层。
In the early sinian , clastic sediments formed by fluvial and continental glacial actions were developed , while in the late sinian , great thickness of marine carbonate rocks formed by two transgression - regression cycles were developed 早震旦世发育由河流作用与陆地冰川作用形成的陆源碎屑沉积；晚震旦世则发育由两次台地盆地台地的海进海退旋回形成的巨厚海相碳酸盐沉积。
Conclusion are obtained as follows : 1 . basin accepted sedimentation since sinian , and strata were well developed . it was marine sedimentary series from sinian to middle - triassic and become continental sedimentary series since late - triassic 主要成果及认识如下： 1 、盆地自震旦纪以来长期接受沉积，地层发育良好，震旦纪至中三叠世为海相沉积体系，晚三叠世以后为陆相沉积体系。
Six lithofacies palaeogeographic maps of doushantuo , dengying , qiongzhusi , canglangpu , and longwangmiao ages of late sinian and early cambrian have been made in the light of dominant facies and in the way to make stratigraphic map 中扬子地区上震旦统发育了从碳酸盐潮坪、开阔台地、浅滩、台地边缘、斜坡到台地前缘盆地等沉积，下寒武统下部主要?细碎屑岩和碳酸盐岩组成的混合型浅海陆棚沉积，上部变成碳酸盐潮坪、开阔台地、台缘斜坡和台缘盆地沉积。
