冰碛岩

震旦纪地层是本区新发现的地层单位，由含泥砾白云岩，砾岩（冰碛岩？）

As a newly discovered stratigraphic unit , the Sinian strata of this area are composed ofboulderclay dolostone , conglomerate ( tillite ?)

通过对冰碛岩沉积特点的研究，分析沉积环境。

Analysis of the sedimentary environment is made according to the characteristics of deposition .

我国修定后的震旦系与埃迪卡拉系完全相当，底界以南沱冰碛岩之上盖帽碳酸盐岩的下界为界。

The redefined Sinian System in China , bounded by the base of the cap carbonate ( the lowermost Doushantuo Fm . ) just above the Nantuo diamictite , quite corresponds with the Ediacaran System .

例如向斜、背斜、断层、盐丘，冰碛层之下结晶岩的顶面起伏形态，矿体以及粘土矿床等。

Among such features may be synclines and anticlines , geological faults , salt domes , undulations of the crystalline bedrock under a cover of moraine , ore bodies , clay deposits and so on .
