The goal of this work was to illustrate a possible interaction between the "soda continent" and the ocean. A laboratory simulation was undertaken of the development of alkaliphilic mat with calcium carbonate and calcium phosphate interlayers in the zone where ocean waters, containing calcium and manganese, come into contact with carbonate- and phosphate-rich alkaline waters. The macrostructure of the layered cyanobacterial mat turned out to little dependent on the chemical conditions causing sediment formation. The chemical composition of freshly formed mineral interlayers of the mat was found to vary with the medium composition. The mineralogical composition of the sediment is determined by diagenesis conditions in its depth, which can cause mineral phase conversions.
这项工作的目标是阐明“苏打大陆”与海洋之间可能存在的相互作用。在含有钙和锰的海水与富含碳酸盐和磷酸盐的碱性水接触的区域，进行了一个实验室模拟，研究具有碳酸钙和磷酸钙夹层的嗜碱菌席的发育情况。结果表明，层状蓝细菌菌席的宏观结构几乎不依赖于导致沉积物形成的化学条件。发现菌席新形成的矿物夹层的化学成分会随介质成分而变化。沉积物的矿物成分由其深度处的成岩条件决定，而成岩条件可能导致矿物相转变。
