Özet
Salda Golu (Lake), in southern Turkey, is a highly alkaline (pH > 9) freshwater lake in which composite stromatolites several metres high are formed by microbially induced precipitation of hydromagnesite. The magnesium and carbonate in the lake waters were dissolved during passage through ultramafic rocks. Precipitation is brought about by the flora of diatoms and cyanobacteria forming the surface of the stromatolites, but does not occur in direct contact with cells. Stromatolites have previously been reported from environments ranging from fully marine through brackish water to a variety of freshwater lacustrine and fluvial situations. The principal importance of these structures lies in their novel mineralogy. Hydromagnesite Mg4(OH)2(CO3)3 . 3H2O is commonly regarded as a low-temperature hydrothermal mineral.
