When the overall tem… The crystals are made from a rock called selenite, which is the crystal form of a mineral called gypsum. These three rock units are the Oneota Dolomite, the New Richmond Sandstone, and the Shakopee formation (also a dolomite). While the ‘Cueva de los Cristales’ offers a stunning spectacle of numerous giant translucent crystals, the stay inside the cave might not be equally pleasant. The cave boasts a rare (yet stable) environment that is hostile to the humans. In order for enormous crystals like the ones in The Cave of Crystals to form, the solution in the cavern had to have cooled extremely slowly, preventing the rapid precipitation typical of super-saturated solutions. Two miners saw the crystals when they entered the drying cave on foot. Crystal Cave of Giants in Mexico from Crystalinks Website The Naica Mine of Chihuahua, Mexico, is a working mine that is known for its extraordinary crystals. November Editorial . A sinkhole is simple the collapse of a cavern and looks like a large hole in the ground. In 2000 Delgado brothers discovered also Queen’s Eye Cavern (Cueva del Ojo de la Reina) at the depth of 300 m. The giant obelisks are formed from groundwater saturated in calcium sulphate which filtered through the cave system millions of years ago. It widens the prospect of the environments that scientists consider to be habitable. Even with the special cooling suit that is worn by the visitors, the time limit inside the cave has been set to about 45 minutes. There must also be an abundance of water to continually move the carbonic acid through the caves. The crystals are said to be 500,000 years old and were formed from the underground magma (situated below the cave) which maintained the water at a stable temperature of 50°C, saturating it with minerals, including gypsum. Credit to Isaac Littman via Geologyin.com. Other caves under the mountain range, witnessed temperature changes and formed smaller crystals. Scientists have estimated the biggest crystal to weight a massive 55 tonnes! The caves are accessible today because the mining companys pumping operations keep them clear of water. Often the ceiling of a cave collapse forming a sink hole that is visible on the surface. If a formation doesn’t satisfy all of the three requirements above the formation can not be considered a cave. Cave of the Swords was the first discovered cavern – specialists speculate that crystals in this cave are smaller because this cave is closer to the land surface and heated water cooled down faster than in the Cave of the Crystals. Also, check out “Fingal’s Cave: The Musical Geometry of Nature’s Domain“. The oxygen slowly diffused into the heated water and oxidized the sulfides (S ) into sulfates (SO4 ) that precipitated as anhydrite(CaSO4). Accordingly, how was the Cave of the crystals formed? Selenite crystals found in the Naica mine formed over hundreds of thousands of years. Necessary cookies are absolutely essential for the website to function properly. The very gradual cooling allowed the crystals to grow over an extended period. “If the researchers who found them are correct, the organisms are still active,” says National Geography’s report on the microbial life found in the cave.
