It is still a spa town with many buildings from
152-638: A pH as low as 0.8, to alkaline chloride springs saturated with silica , to bicarbonate springs saturated with carbon dioxide and carbonate minerals . Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles , microorganisms adapted to extreme conditions, and it is possible that life on Earth had its origin in hot springs. Humans have made use of hot springs for bathing, relaxation, or medical therapy for thousands of years. However, some are hot enough that immersion can be harmful, leading to scalding and, potentially, death. There
228-438: A 3.48 billion year old geyserite that seemingly preserved fossilized microbial life, stromatolites, and biosignatures. Researchers propose pyrophosphite to have been used by early cellular life for energy storage and it might have been a precursor to pyrophosphate. Phosphites, which are present at hot springs, would have bonded together into pyrophosphite within hot springs through wet-dry cycling. Like alkaline hydrothermal vents,
304-401: A complex community of microorganisms that includes Spirulina , Calothrix , diatoms and other single-celled eukaryotes , and grazing insects and protozoans.

#17327727690463952-408: The evolution of early life. For example, in a bicarbonate hot spring, the community of organisms immediately around the vent is dominated by filamentous thermophilic bacteria , such as Aquifex and other Aquificales , that oxidize sulfide and hydrogen to obtain energy for their life processes. Further from the vent, where water temperatures have dropped below 60 °C (140 °F), the surface
4028-555: The fluids is thereby lowered to values as low as 0.8. The acid reacts with rock to alter it to clay minerals , oxide minerals , and a residue of silica. Bicarbonate hot springs are fed by hydrothermal fluids that form when carbon dioxide ( CO 2 ) and groundwater react with carbonate rocks . When the fluids reach the surface, CO 2 is rapidly lost and carbonate minerals precipitate as travertine , so that bicarbonate hot springs tend to form high-relief structures around their openings. Iron-rich springs are characterized by
4104-526: The formation of biopolymers which are then encapsulated in vesicles after rehydration. Solar UV exposure to the environment promotes synthesis to monomeric biomolecules. The ionic composition and concentration of hot springs (K, B, Zn, P, O, S, C, Mn, N, and H) are identical to the cytoplasm of modern cells and possibly to those of the LUCA or early cellular life according to phylogenomic analysis. For these reasons, it has been hypothesized that hot springs may be
4180-629: The groundwater originates as rain and snow ( meteoric water ) falling on the nearby mountains, which penetrates a particular formation ( Hollis Quartzite ) to a depth of 3,000 feet (910 m) and is heated by the normal geothermal gradient. Because heated water can hold more dissolved solids than cold water, the water that issues from hot springs often has a very high mineral content, containing everything from calcium to lithium and even radium . The overall chemistry of hot springs varies from alkaline chloride to acid sulfate to bicarbonate to iron-rich , each of which defines an end member of
4256-400: The heat is created by decay of naturally radioactive elements. An estimated 45 to 90 percent of the heat escaping from the Earth originates from radioactive decay of elements mainly located in the mantle. The major heat-producing isotopes in the Earth are potassium-40 , uranium-238 , uranium-235 , and thorium-232 . In areas with no volcanic activity, this heat flows through the crust by
4332-669: The high concentrations of ionic solutes there would inhibit the formation of membranous structures. David Deamer and Bruce Damer note that these hypothesized prebiotic environments resemble Charles Darwin 's imagined "warm little pond". If life did not emerge at deep sea hydrothermal vents, rather at terrestrial pools, extraterrestrial quinones transported to the environment would generate redox reactions conducive to proton gradients. Without continuous wet-dry cycling to maintain stability of primitive proteins for membrane transport and other biological macromolecules, they would go through hydrolysis in an aquatic environment. Scientists discovered

4788-658: The place of origin of life on Earth. The evolutionary implications of the hypothesis imply a direct evolutionary pathway to land plants. Where continuous exposure to sunlight leads to the development of photosynthetic properties and later colonize on land and life at hydrothermal vents is suggested to be a later adaptation. Recent experimental studies at hot springs support this hypothesis. They show that fatty acids self-assemble into membranous structures and encapsulate synthesized biomolecules during exposure to UV light and multiple wet-dry cycles at slightly alkaline or acidic hot springs, which would not happen at saltwater conditions as

Some hot springs produce fluids that are intermediate in chemistry between these extremes. For example, mixed acid-sulfate-chloride hot springs are intermediate between acid sulfate and alkaline chloride springs and may form by mixing of acid sulfate and alkaline chloride fluids. They deposit geyserite, but in smaller quantities than alkaline chloride springs. Hot springs range in flow rate from
4940-599: The scientific basis for therapeutic bathing in hot springs is uncertain. Hot bath therapy for lead poisoning was common and reportedly highly successful in the 18th and 19th centuries, and may have been due to diuresis (increased production of urine) from sitting in hot water, which increased excretion of lead; better food and isolation from lead sources; and increased intake of calcium and iron. Significant improvement in patients with rheumatoid arthritis and ankylosing spondylitis have been reported in studies of spa therapy, but these studies have methodological problems, such as

Iron-rich hot springs contain communities of photosynthetic organisms that oxidize reduced ( ferrous ) iron to oxidized ( ferric ) iron. Hot springs are a dependable source of water that provides a rich chemical environment. This includes reduced chemical species that microorganisms can oxidize as
5396-443: The water in the cistern, raising its temperature above the normal boiling point. The water will not immediately boil, because the weight of the water column above the cistern pressurizes the cistern and suppresses boiling. However, as the superheated water expands, some of the water will emerge at the surface, reducing pressure in the cistern. This allows some of the water in the cistern to flash into steam, which forces more water out of
