本文采用GC＿MS、ICP＿MS、形态硫分析、硫同位素、物相分析等方法综合研究了湘西晚震旦世-早寒武世黑色岩系的地球化学特征和形成条件。

This paper deals with the formation conditions of black shales based on such analytical techniques as ICP_MS , GC_MS , isotope , organic carbon , element facies and micropetrology .

同时，运用HSI（生境选择适合度指数）模型，对震旦鸦雀冬季种群的觅食生境进行了初步评价和探讨。

And meanwhile , Habitat Selection Index Model was used to estimate the foraging habitat of Reed Parrotbill population in winter .

震旦系层间破碎带控制的Sb、Au异常和花岗岩体内断裂破碎带Au异常亦有一定找矿前景。

The Sb + Au anomalies controlled by interlayer crushed zone of Sinian System and Au anomaly in fracture zone within granite body should provide a certain prospect for prospecting .

推覆体主要为震旦系、寒武系的灰岩，由NW→SE推覆掩盖在志留系页岩之上，主滑脱面倾角较小（10°～20°）。

Thrust nappes consist of the limestone of Sinian and Cambrian which thrusted over the shale of Silurian with NW → SE thrust direction and had a drape cline thrust surface .

变形体和危岩体主要分布在1000m高程左右，岩性主要为二叠系下统角砾状灰岩、石英角砾岩等分布地带，少量发育在震旦系白云质灰岩中；

Distortion and dangerous rock mass is distributed in the area at 1000m which lithology is limestone of Sinian and breccia of Permian .

这一定年结果是目前中国震旦（埃迪卡拉）系陡山沱组底部首次获得的SHRIMP锆石U-Pb年龄。

It is the first SHRIMP U-Pb zircon age obtained nearly the base of the Sinian ( Ediacaran ) Doushantuo Formation and represents a maximum age of the Doushantuo Formation .

葫芦磷矿床位于古丈背斜南西端，含磷岩系赋存于震旦系陡山沱组下部，总厚度10m、分为ABCDEF沉积序列。

Hulu phosphorus deposit is situated in the southwestern end of Guzhang anticline . The phosphorus-bearing rock series lies in the lower part of Doushantuo Formation of Sinian , with a total thickness of 10m , which can be divided into A-B-C-D-E-F sedimentary sequences .

这一构造系统形成于前震旦纪，可能与格林威尔（Grenville）造山运动相当。

This structural system was formed in the pre - Sinian , probably related to the Grenville orogenic event .

作者以巢县地区震旦系到三叠系的碳酸盐岩为例，探讨了在不同成岩环境下，碳酸盐岩中微量元素Sr、Na、Fe、Mn的分布特征。

Abstract The paper deals with the distribution of trace elements , such as Sr. Na , Fe . Mn in carbonate rocks occurred under various diagenetic environments with a case study of the carbonate rocks ( Z-T ) in the Chao County .

震旦系以上地层大量暴露，地表水溶蚀下渗深度在黔西南地区可达3000～4000m；

The overlying strata on Sinian rocks are all exposed and surface water has leaked down and solved into 3000 ~ 4000m of depth in southwestern Guizhou .

华北块体（NCB）与胶辽朝块体（JLKB）是中朝板块东部从震旦纪（680Ma）开始裂解的两个不同的构造单元。

In the Sinian ( 680Ma ), the Sino-Korean plate began to break up into two different tectonic units , the Jiao - Liao - Korea block ( JLKB ) and North China block ( NCB ) .
