SINOPSIS

In studies of the Kamchatka geyserite specimens by a scanning electron microscope it was possible to reveal various mineralized microbiota of Cyanophyta, which was silicified under extreme temperature conditions of hydrothermal systems. Thermophilic blue-green algae and other microbiota form the microstructure and texture of the formations under study. An assumption is advanced about the physiological activity of microbiota as a bacterial matrix in the process of siliceous deposits.
