Depositional facies and aqueous-solid geochemistry of travertine-depositing hot springs (Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, U.S.A.).
Petrographic and geochemical analyses of travertine-depositing hot springs at Angel Terrace, Mammoth Hot Springs, Yellowstone National Park, have been used to define five depositional facies along the spring drainage system. Spring waters are expelled in the vent facies at 71 to 73 degrees C and precipitate mounded travertine composed of aragonite needle botryoids. The apron and channel facies ...
متن کاملDepositional Facies and Aqueous–solid Geochemistry of Travertine-depositing Hot Springs (angel Terrace, Mammoth Hot Springs, Yellowstone National Park, U.s.a.)— Discussion
Terrestrial CaCO3 precipitates, including travertines, tufas, and speleothems, are currently of great interest because of their potential as archives of environmental, climatic, and biologic information (e.g., Andrews et al. 1997; Bar-Matthews et al. 1997; Walter and Des Marais 1993). Detailed studies of examples of these terrestrial carbonates therefore provide valuable information to aid inte...
متن کاملNematode feediNg types iN a tufa-depositiNg eNviroNmeNt (plitvice lakes, croatia)
Free-living nematodes are an important group in all benthic habitats. They occur in high abundance and due to the feeding types they have strong influence on bacteria, algae, detritus and meiofauna in periphyton and sediments. The main aims of this study were to determine the vertical distribution of nematodes and their feeding types within the moss-covered tufa barrier over a one year period i...
متن کاملOrigin and hydrogeochemical evolution of Azarshahr travertine springs, NW Iran
1-Introduction Travertines are limestones that form where hot groundwaters rich in calcium and bicarbonate emerge at springs. Travertines cover a large area southwest of Azarshahr (East Azarbaijan province), in some parts of which active springs are currently settling travertine. One of the main questions about travertine springs is their origin, as well as the secondary processes that have ch...
متن کاملPhage Communities in Hot Springs
Boiling thermal pools are unique ecosystems to study microbial ecology, biogeochemistry and evolution, because they are physically isolated from other ecosystems, they are relatively biologically simple, and they are among the most hostile environments known. The water column of boiling hot springs represents an extreme environment that has not been previously explored for viruses or microbes. ...
