Ochtinská Aragonite Cave - Wikipedia
Ochtinská Aragonite Cave (Slovak: Ochtinská aragonitová jaskyňa, Hungarian: Martonházi-aragonitbarlang [citation needed]) is a unique aragonite cave situated in southern Slovakia, near Rožňava. Although only 300 m long, it is famous for its rare aragonite formations. [2]
Aragonite - Wikipedia
In the US, aragonite in the form of stalactites and "cave flowers" is known from Carlsbad Caverns and other caves. [10] For a few years in the early 1900s, aragonite was mined at Aragonite, Utah (now a ghost town).
Aragonite - National Speleological Society
But even as they speak, cave aragonite grows on, seemingly in open defiance of the laws of chemistry. Its secret: a loophole clause known as “magnesium-poisoning”. “Magnesium-poisoning” is the name given by carbonate geologist Robert Folk to the phenomenon by which certain solutions supersaturated with respect to calcite are inhibited ...
The Deposition of Calcite and Aragonite in Caves
The influence of the composition of the solution on the percentages of calcite and aragonite formed has been studied. Factors directly favoring the formation of aragonite under cave conditions are high temperature, low concentration of calcium bicarbonate, and high concentrations of magnesium, strontium, and lead.
The Virtual Cave: Aragonite & Frostwork - National Speleological …
Bushes of acicular aragonite crystals are also known as frostwork, as in the top photo. If you simply can't resist the urge to ire some student of mineralogy, remind them that aragonite and calcite are happy bedfellows in many caves.

Ochtinská Aragonite Cave - SSJ
Ochtinská Aragonite Cave represents a unique natural phenomenon drawing attention by the richness and variety of aragonite fill, as well as an interesting evolution and development of cave spaces.
Modern aragonite formation at near-freezing conditions in an …
2016年10月1日 · Li et al. (2011) examined modern and inactive aragonite stalagmites in Furong Cave, central China, and showed that aragonite formed at isotopic equilibrium at a temperature of about 16 °C. Here we report evidence of active aragonite precipitation at much lower temperatures, close to 0 °C, which are the first documented modern aragonitic ...
Effect of aragonite to calcite transformation on the geochemistry …
2019年4月1日 · To provide some insights to these modifications, this study combines stable isotope geochemistry and U-series dating with petrological observations and EMPA elemental analyses to characterize a stalagmite from Castañar Cave (Cáceres, Spain) that shows primary aragonite diagenetically altered and with reverse ages.
Ochtinská Aragonite Cave - Amusing Planet
2016年7月30日 · The Ochtinská Aragonite Cave, in southern Slovakia, is one of the few caves in the world where aragonite crystals are found. There is one in the Czech Republic (Zbrašov aragonite caves) and other caves are located in Brazil, Argentina, Mexico and the United States, but the aragonite fillings in Ochtinská Aragonite Cave is by far the most ...
