Mineral-microbe interactions and biomineralization of siliceous sinters and underlying rock from Jenn's Pools in the Uzon Caldera, Kamchatka, Russia
Siliceous sinters were collected from two high temperatures, disaerobic, reducing terrestrial hot springs from the Uzon Caldera, Kamchatka, Russia for the purpose of characterizing microbe-mineral interactions, and biomineralization of the sinters, associated microbial mats, and underlying rocks.
