Don’t have a SeatHot springs commonly form either on silicate rocks, like most of the crust, or occasionally on limestones. When a hot spring sits on a limestone, it tends to be more active and unpredictable. Carbonate minerals are easier to dissolve in high-temperature water than silicate minerals, so hot springs on carbonate rocks will precipitate minerals more rapidly and grow outwards more rapidly. They can also switch the locations where they are actively erupting rapidly; precipitating carbonate minerals can clog up one path that water is taking and force it to find other fractures.Sometimes, these active hot springs will encroach upon something humans have built. In Yellowstone National Park, Mammoth Hot Springs has a location known as Opal Terrace that began erupting in 1926 and forced the removal of a nearby tennis court. In this case, at Pamukkale in Turkey, a hot spring is on the verge of consuming a bench.-JBBImage credit: https://flic.kr/p/28kEUKFReference:https://www.nps.gov/features/yell/tours/mammoth/opalterr.htm -- source link
