Geyserite - Wikipedia
Geyserite, or siliceous sinter, is a form of opaline silica that is often found as crusts or layers around hot springs and geysers. Botryoidal geyserite is known as fiorite. Geyserite is porous due to the silica enclosing many small cavities. [1] . Siliceous sinter should not be confused with calcareous sinter, which is made of calcium carbonate.

One of the most enticing attractions for visitors arriving in Yellowstone National Park every year is the park's iconic geysers—about half of all geysers in the world are in Yellowstone! As scientists, we are interested in understanding how geysers work for a variety of reasons.
Geyserite Meanings and Crystal Properties
Geyserite is an opaline silica mineral that crystallizes in the form of stalactites, crusts, botryoidal, fibrous, and masses. The color is usually a light brown, due to the Rhyolite rock located directly underneath most geysers (there have also been reports of Obsidian (Black) …

2015年9月1日 · Geyserites are sinters affiliated with the highest temperature (~ 75–100 °C), natural geothermal fluid emissions, comprising localized, lithologically distinctive, hydrothermal silica precipitates that develop around geysers, spouters and spring-vents.
GEYSERITE
Geyserite is the name given to siliceous or calcareous mineral deposits at & in the vicinity of hot springs and geysers. Such mineral deposits are typically composed of opaline silica (SiO2·nH2O), but sometimes they are calcareous, resulting in a surficial travertine deposit (e.g., Mammoth Hot Springs, Wyoming).
