深海盆地

南海深海盆地沉积柱样中的浊流沉积

Fine-grained turbidite deposits from deep - sea basin in South China Sea

这是重要的，因为褶皱基底和被侵蚀基底在深海盆地中决不是少见的。

This is important , as folded and eroded basements are by no means uncommon in deep basins .

沉积环境类型可概括为冰湖&浅海盆地、盆缘斜坡、半深海盆地。

Besides , the sedimentary environment are classified in the following type : ice lake-neritic basin ; inclines of basin margin ;

上三叠统在南、北坳陷为次深海盆地相沉积，发育一套黑色页岩烃源层；

The Upper Triassic Formation is sub-abysmal basinal facies deposit in the south and north depressions . A black shale layer developed .

本地区奥陶系发育台地相、广海陆棚相、盆地边缘斜坡相、深海盆地相、半深海相和浅海相等类型。

In the study area , the platform , open continental shelf , shelf margin slope , deep sea basin and shallow sea sedimentary facies were developed .

烃源岩沉积于比较安静、还原性强的欠补偿的环境，如半深湖&深湖相、泻湖、沼泽相、浅海大陆架、堰塞小洋盆和毗邻大陆架的深海盆地等。

Hydrocarbon source rock formed in the calm and strong reductive environment , for example half-deep lake-deep facies , estuarine facies , shallow-sea fades and paludal facies etc.

中上奥陶统则为超补偿的半深海盆地（以厚度巨大的浊积岩为特征）-混积陆棚沉积，总体不利于烃源岩发育。

Middle-late Ordovician is super-compensatio nal bathyal basin ( it ` s feature is turbidite ) and mixed continental shelf deposit . It is not favourable for the development of hydrocarbon source rock .

在对五峰组沉积速率、生态及沉积特征等分析基础上，认为五峰组页岩段和琨音桥段均形成于深海盆地环境中。

Based on the analysis of the sedimentary rate , ecologic and sedimentary aspects , it is believed that both the Wufeng shale Member and the Guanyingqiao Member are formed in deep sea basin environment .

本文研究的特提斯硅质岩来源丰富，代表了深海盆地、洋岛、岛弧、大陆边缘、深海再沉积乃至浅海陆棚等多种构造-沉积环境与作用。

Siliceous rocks from Paleo-Tethys refer to my paper , fromed in the deep-sea basins , oceanic islands , island arc , continental margin , deep-sea resedimentation and even shallow shelf and other tectonic - sedimentary environment .

塔里木盆地中上奥陶统碳酸盐岩烃源岩在同一时期不同的沉积环境（台缘斜坡、台地内凹陷、陆棚、深海盆地等）中均有发育。

The carbonate source rocks of Middle-Upper Ordovician in Tarim basin are widely distributed in different sedimentary environments at the same period such as platform margin slope , platform inner sag , continental shelf , abyssal basin , etc.

自古生代以来，该地区没有出现深海大洋盆地环境。

Since the Paleozoic the tectonic environment of deep oceanic basins was not developed in this region .

遗迹化石及遗迹相特征反映该区上三叠统雅江组和两河口组的沉积环境为次深海深海的大陆斜坡中下部深海盆地边缘。

In term of trace fossils , it is suggested that the Late Triassic depositional environment in the area experienced the evolution from the middle-lower slope to abyssal basin margins .
