There must also be an abundance of water to continually move the carbonic acid through the caves. Giant elongate selenite mega crystals, the biggest ever found on the planet, grow from some of these groups of blocky crystals or directly from the floor, and some criss-cross the cave from side to side. And recently, Dr.Penelope Boston of NASA's Astrobiology Institute was able to isolate dormant microbes inside the crystals and revive them. The oxygen slowly diffused into the heated water and oxidized the sulfides (S ) into sulfates (SO4 ) that precipitated as anhydrite(CaSO4). If a formation doesn’t satisfy all of the three requirements above the formation can not be considered a cave. They are forever. Caves must also be far enough from the entrance to be able to achieve total darkness. Naica lies on an ancient fault above an underground magma chamber which is approximately 3–5 kilometres (2–3 mi) below the cave.

Super heated fluids carry the mineral-rich sludge which formed the crystals as well as the mineral veins. It is also called Cave of the Crystals because it is actually made up of three caves that are co-joined … The sinkhole above is visible from the earth's surface. Selenite crystals found in the Naica mine formed over hundreds of thousands of years. While the cave appears inhabitable, there is a lot of activity going on at microbial level. Caves are formed when rain mixes with CO2 forming carbonic acid (H2CO3). These cookies will be stored in your browser only with your consent. The selenite crystals were formed by hydrothermal fluids heated by the magma chamber below. Enjoyed this article? Over the period of time, these crystals grew to abnormal sizes, thanks to the rare cave environment that has been stable for more than 10,000 years. How did the gypsum crystals reach such superheroic proportions? Most of these microbes have slowed their metabolism to extreme levels or are in a dormant state. Accordingly, how was the Cave of the crystals formed? Also called Giant Crystal Cave, it’s nearly the size of a basketball court. Selenite. A clue to this ubiquity can be found in our everyday speech. It harbors smaller crystals but has its wall full of dagger sized crystals, hence the name, ‘Cave of Swords’. The crystals began to grow because of water boiling in this underground chamber. 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. The cavern was discovered while the miners were drilling through a newly drained area. The researchers and scientists have been actively studying the cave since 2001. These crystals are made of a mineral called celestine, which is a form of strontium sulfate. The crystals are made from a rock called selenite, which is the crystal form of a mineral called gypsum. Further studies about these microbes will help scientists learn about new places and harsher environments where life can exist. Yes, salt, sugar and ice are crystals, too, just like the gems, metals, fluorescent paints and liquid crystals we mentioned. As the mountain got cooler, researchers believe that the cave was flooded with calcium sulphate enriched water, which reacted with the anhydrite, leading to the formation of these selenite-gypsum crystals. Cueva de los Cristales, known as the Giant Crystal Cave or Cave of the Crystals in English, is a true testimony of how beautiful our mother nature can be. A sinkhole is simple the collapse of a cavern and looks like a large hole in the ground. Often the ceiling of a cave collapse forming a sink hole that is visible on the surface. Psst!

The largest crystal of Giant Crystal Cave is said to reach a length of 12 metres (39 feet), a diameter of 4 metres (13 feet) and is believed to weigh approximately 50 tonnes (55 tons). The crystals were discovered after the water was pumped out of the mine. This water was rich in gypsum minerals, and the heat generated by the magma worked like a cooker, maintaining a steady heat for 500,000 years. Obelisks shaped crystals up to 37 feet (11 meter) in length and the equivalent height of six men jutted out from the damp rock walls, and there were hundreds of blade-sharp crystals. It was above the recently discovered ‘Cave of the Crystals’ and relatively closer to the ground at a depth of about 120 meters. Also, check out “Fingal’s Cave: The Musical Geometry of Nature’s Domain“. It widens the prospect of the environments that scientists consider to be habitable. “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. These three rock units are the Oneota Dolomite, the New Richmond Sandstone, and the Shakopee formation (also a dolomite). When carbonic acid dissolves limestone (CaCO3) it produces calcium bicarbonate (Ca(HCO3)2) in solution. The cave contains some of the largest natural selenite … Scientists have estimated the biggest crystal to weight a massive 55 tonnes! HAVE A GROOVY NEW YEAR!

Microbial life forms that survive off sulphur, iron and several other chemical compounds have been found here. The chamber holding these crystals is known as the Crystal Cave of Giants, and is … 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 photograph above is an example of a joint or fracture in the rock where carbonic acid flowed causing the limestone to errode. As a consequence, without proper equipment, a person cannot survive here for more than 15 minutes. Scientists and researchers have been actively working in the Cave of Crystals since 2001, and continued to do so until its confirmed flooding in 2017. Click the snowman for more details! The crystals deteriorate in air, so the Naica Project is attempting to visually document the crystals before they deteriorate further. Using uranium dating, scientists were able to determine that the crystals were 500,000 years old. These organisms at a minimum are about 10,000 years old. 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. Without the presence of sinkholes it is often hard to discover a cave formation. The anhydrite slowly enriched the waters with sulfate and calcium molecules, which for millions of years have been deposited in the caves in the form of huge selenite gypsum crystals. In this crystal cave you can see crystals of up to 1 m long. This allowed crystals to form and grow to immense sizes. However, things can go wrong.
