Laboratory biomodels of sulfuric algal-bacterial mat and rings of sulfur (Karpov's Rings)


ABSTRACT

Two interesting sulfuric formations were studied in hydrothermal fields of the caldera of the Uzon Volcano (Kamchatka): (1) a sulfuric stratified algal-bacterial (algobacterial) mat; and (2) horizontal rings of sulfur on the water surface (Karpov's Rings) formed near the growing colonies of blue-green algae (cyanobacteria). These formations are conditioned by the growth of blue-green algae (genera Oscillatoria and Phormidium belonging to the family Oscillatoriaceae) and the pulsating release of sulfur from hydrothermal springs. The biomodels obtained in the laboratory are similar in their morphology to the natural samples.
