2·This paper analyses the growing process of columnar stromatolites.
本文就柱状叠层石的生长过程作一简要的分析。
3·Overall, the frequently fluctuated lacustrine conditions and the surrounding tectogenesis are mainly responsible for the greatly varied form, different genesis of stromatolites.
柴达木盆地频繁变化的湖相水体条件和周围的构造运动是叠层石形态多样，成因各异的主要外部和环境因素。
4·The blue-green algae that form the stromatolites helped create our present atmosphere by breaking down carbon dioxide and excreting oxygen.
