晚震旦世 的英文怎麼說
中文拼音 [wǎnzhèndànshì]
晚震旦世
英文
late sinian epoch-
We have concluded that the structural movement of the area can be divided into three stages : the stretching stage from simian to early ordovician, the extrusion and rising stage from middle and late ordovician to jurassic and stable depressed stage of foreland basin slope from cretaceous to neozoic
經研究認為研究區的構造運動，主要分為震旦紀到早奧陶世的拉張階段、中晚奧陶世到侏羅紀的擠壓隆升剝蝕階段以及白堊紀到新生代的前陸盆地斜坡穩定沉降階段。Sedimentation - diagenesis deposits mainly formed during late sinian to cambrian period, such as bingtongshan pbzn deposits and aozigang deposits
沉積成巖型鉛鋅礦主要成礦時代屬晚震旦世~寒武紀，如冰洞山式鉛鋅礦床和凹子崗鋅礦床。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
早震旦世發育由河流作用與陸地冰川作用形成的陸源碎屑沉積；晚震旦世則發育由兩次臺地盆地臺地的海進海退旋迴形成的巨厚海相碳酸鹽沉積。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
主要成果及認識如下： 1 、盆地自震旦紀以來長期接受沉積，地層發育良好，震旦紀至中三疊世為海相沉積體系，晚三疊世以後為陸相沉積體系。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
由於地殼差異性升降運動，晚震旦世陡山沱期巖相古地理格局發生了急劇變化。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
晚震旦世巖相古地理格局由碳酸鹽臺地（鄂中臺地）和南邊的臺緣盆地組成。分享友人
