PP‐25cyanobacterial mat, mineralogical and structural features of the Garga carbonate body werethoroughly studied by complex of physical‐chemical methods.The result obtained allowed the conclusion about the history of formation of the Gargacarbonate body. This carbonate structure was formed as a result both of the deposition ofminerals from the hot spring stream and of the activities of cyanobacterial community.The financial support by Integration Project No. 10 of the Siberian Branch of RAS, by theRFBR (11‐05‐00717), RF President Grant for the Leading Scientific Schools (#NSh3156.2010.3) and Program “Origin of biosphere and evolution biogeology systems” ofPresidium of RAS is gratefully acknowledged.[1].
