Hamilton, University of Minnesota Twin Cities, United States Lake Dziani Dzaha is a thalassohaline tropical crater lake located on the “Petite Terre” Virginia Helena Albarracín, Island of Mayotte (Comoros archipelago, Western Indian Ocean). Stromatolites are Center for Electron Microscopy (CIME), Argentina actively growing in the shallow waters of the lake shores. These stromatolites are *Correspondence: mainly composed of aragonite with lesser proportions of hydromagnesite, calcite, Emmanuelle Gérard dolomite, and phyllosilicates.
