Use of Morphology of Halophilic and Alkaliphilic Cyanobacteria as a Criterion for Detection of Soda Conditions in the Past

Аннотация

The modern soda lakes as relict biotopes, the analogs of which could be widespread in the Precambrian Era, are considered in the context of two hypotheses: “soda ocean” and “soda continent.” The diversity of modern halophilic and alkaliphilic cyanobacteria has been analyzed in order to reveal the morphological forms which have paleo-analogs that could be used as indicators of soda conditions in the Precambrian.
