To be more precise, this hidden cave is present at a depth of 300 meters measured from the surface and produces selenite-gypsum-crystals that can get as big as 12 meters in height. The walls and particularly the floor of the cave are sprinkled with blocky single crystals that in some cases cluster to form a parallel aggregate. These crystals are made of a mineral called celestine, which is a form of strontium sulfate. Cave of the Crystals is connected to the Naica Mine at a depth of 300 meters (980 feet). It widens the prospect of the environments that scientists consider to be habitable. 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. Cave of Crystals . Microbial life forms that survive off sulphur, iron and several other chemical compounds have been found here. The caverns became flooded over time as a result of groundwater seeping in. Caves are formed when rain mixes with CO2 forming carbonic acid (H2CO3). In fact, most minerals naturally occur in a crystalline form [source: Smithsonian]. The Oneota and … 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. Naica lies on an ancient fault above an underground magma chamber which is approximately 3–5 kilometres (2–3 mi) below the cave. While these extreme weather conditions are very unsympathetic to humans, they provide an ideal environment for the crystals to grow. “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. The Cave of Crystals is a cave approximately 300 m (1,000 ft) below the surface in the limestone host rock of the mine. There must also be an abundance of water to continually move the carbonic acid through the caves. If these so-called "extremophiles" can form and thrive on our planet in challenging conditions, then chances are good that microbes can exist … ... specially designed gear, which allows the explorer … And recently, Dr.Penelope Boston of NASA's Astrobiology Institute was able to isolate dormant microbes inside the crystals and revive them. When the overall tem… These microbes find no place in our existing database and are ‘alien’ to the scientists. These giant crystals have experienced steady slow growth over the past half a million years. These cookies do not store any personal information. Temperatures hovered consistently around a steamy 136 degrees Fahrenheit (58 degrees Celsius), and the cave was filled with mineral-rich water that drove the crystals' growth. Collecting samples for further study. Some of the crystals are the size of a bus. The cave was accidentally discovered by two miners in 2000 who were trying to excavate ‘a new tunnel for a commercial lead and silver mine’ for a Naica based mining company called Industrias Peñoles. Website Created by Pat Dryer and Mike Mc Evoy. 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). Celestine crystals. In 2000 Delgado brothers discovered also Queen’s Eye Cavern (Cueva del Ojo de la Reina) at the depth of 300 m. While the cave appears inhabitable, there is a lot of activity going on at microbial level. The chamber contains giant selenite crystals, some of the largest natural crystals ever found. Strontium salts, specifically strontium carbonate and nitrate, are widely used to make fireworks. 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. This filled the mountain with “high-temperature anhydrite, which is the anhydrous—lacking water—form of gypsum.”. November Editorial . Also called Giant Crystal Cave, it’s nearly the size of a basketball court. In this crystal cave you can see crystals of up to 1 m long. But opting out of some of these cookies may have an effect on your browsing experience. The selenite crystals were formed by hydrothermal fluids heated by the magma chamber below. 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. The photograph above is an example of a joint or fracture in the rock where carbonic acid flowed causing the limestone to errode. Peru. Scientists have estimated the biggest crystal to weight a massive 55 tonnes! The sinkhole above is visible from the earth's surface. It is also called Cave of the Crystals because it is actually made up of three caves that are co-joined … 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. Psst! Often the ceiling of a cave collapse forming a sink hole that is visible on the surface. 12 Days of Groovy • Save Up to $44.00! Without the presence of sinkholes it is often hard to discover a cave formation. When carbonic acid dissolves limestone (CaCO3) it produces calcium bicarbonate (Ca(HCO3)2) in solution. In other parts of the site: a database of rocks and minerals, places to visit and places to shop, general information on rocks, chemical and optical properties of rocks and minerals. Necessary cookies are absolutely essential for the website to function properly. The Naica Mine happens to be situated on a ‘set of false lines’.

Approximately 2-3 miles (3-5km) under the surface is a giant pool of magma. The crystals must be at least 60,000 years old, the team found, because that was the youngest age of a bit of carbonate crust growing on one of the largest crystals in the geode. This is a slow process and takes thousands of years to from 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. Accordingly, how was the Cave of the crystals formed? Whilst u… The crystals were discovered after the water was pumped out of the mine. Yet, as Cave of the Crystals demonstrates, microbes can survive extreme conditions, such as in desert regions or deep underwater, or even encased in rocks and minerals. The very gradual cooling allowed the crystals to grow over an extended period. The giant obelisks are formed from groundwater saturated in calcium sulphate which filtered through the cave system millions of years ago. Crystal cave, Ohio. A clue to this ubiquity can be found in our everyday speech. Its floor is covered with perfectly faceted crystalline blocks. This extreme temperature is accompanied by a high level of humidity varying from 90 to 99 percent. Selenite crystals found in the Naica mine formed over hundreds of thousands of years. The magma heated the ground water which was saturated with sulfide ions (S ). 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.
