Results The morphology and asexual reproduction of Cloudina are broadly similar to modern serpulid annelids and its flourishing is somewhat coeval and corresponding to a positive excursion of δ13C.

结果 Cloudina可能是多毛类龙介虫，二者在管体形态特征、无性繁殖方式等方面存在可比性；Cloudina的出现都对应着碳同位素的明显正漂移，具有基本等时的特点。

There are two evolutional trends for sodic basalts: alkaline basalt to sub-alkaline basalt and to the contrary. The fact that alkaline basalt has the higher concentration of incompatible elements and the sub-alkaline lower indicates the increasing degree of the partial melting in the mantle sources. The variety of Sr, Nd isotope compositions in different types of rocks shows their different mantle sources.

钠质玄武岩存在着碱性玄武岩到亚碱性玄武岩和亚碱性玄武岩到碱性玄武岩的变化序列；碱性玄武岩到亚碱性玄武岩不相容元素丰度逐渐降低，表明为部分熔融程度逐渐增高的产物；Sr、Nd同位素组成与岩性之间的相关性表明，各种岩浆是不同地幔源区部分熔融的产物。
