However, things can go wrong. Collecting samples for further study. The massive giant crystals were discovered in 2000 after water was pumped out of the cave by a mining company. The photograph above is an example of a joint or fracture in the rock where carbonic acid flowed causing the limestone to errode. This can help NASA scientists to study the conditions on other planets and the subsequent possibility of life there. Cave of Crystals. In the new issue of the journal Geology, García-Ruiz reports that for millennia the crystals thrived in the cave’s extremely rare and stable natural environment. Located just below the Naica Mine, Chihuahua, Mexico, this cave is literally ‘full’ of gigantic natural crystals that can easily overshadow anything that is about the size of a human. Researchers exploring the cave. Around 26 million years ago, a Volcanic activity created the Naica mountain. The caves are accessible today because the mining companys pumping operations keep them clear of water. (Alexander Van Driessche / Wikimedia Commons). But opting out of some of these cookies may have an effect on your browsing experience. Cave of the Crystals or Giant Crystal Cave is a cave in Naica, Chihuahua, Mexico. Often the ceiling of a cave collapse forming a sink hole that is visible on the surface. ... Cave of the Crystals, contains some of the largest crystals ever . This website uses cookies to improve your experience. The chamber holding these crystals is known as the Crystal Cave of Giants, and is … The water boiled for about 500,000 years. (La Venta – Geographical explorations). (La Venta – Geographical explorations). It was above the recently discovered ‘Cave of the Crystals’ and relatively closer to the ground at a depth of about 120 meters. The cave contains crystals formed of the selenite form of gypsum (calcium sulphate). NASA’s Astrobiology Institute director, Penelope Boston, said that these ‘organisms are genetically distinct from anything known on Earth’. Worlds Largest. “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. We'll assume you're ok with this, but you can opt-out if you wish. And recently, Dr.Penelope Boston of NASA's Astrobiology Institute was able to isolate dormant microbes inside the crystals and revive them. Caves are formed when rain mixes with CO2 forming carbonic acid (H2CO3). HAVE A GROOVY NEW YEAR! 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. The reason lies beneath the cave. 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. The oxygen slowly diffused into the heated water and oxidized the sulfides (S ) into sulfates (SO4 ) that precipitated as anhydrite(CaSO4). In 2000 Delgado brothers discovered also Queen’s Eye Cavern (Cueva del Ojo de la Reina) at the depth of 300 m. 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. If these so-called "extremophiles" can form and thrive on our planet in challenging conditions, then chances are good that microbes can exist … The cave was discovered in April 2000 by miners excavating a new tunnel for the Industrias Peñoles mining company located in Naica. ... Super heated fluids carry the mineral-rich sludge which formed the crystals as well as the mineral veins. Often the ceiling of a cave collapse forming a sink hole that is visible on the surface. The cave in which these crystals are found was filled with water for thousands of years, and the crystals are thought to have formed extremely slowly – so slowly, that they cannot recreate the process in a lab. The Naica Mine happens to be situated on a ‘set of false lines’. In this crystal cave you can see crystals of up to 1 m long. Two miners saw the crystals when they entered the drying cave on foot. Naica is a lead, zinc and silver mine in which large voids have been found, containing crystals of selenite (gypsum) as large as 4 feet in diameter and 50 feet long. Temperatures hovered consistently around a steamy 136 degrees Fahrenheit (58 degrees Celsius), and the cave was filled … The Prairie du Chien group was formed over 400 million years ago in the Ordovician when Wisconsin was covered in a sea. Click the snowman for more details! Fact Analysis: STSTW Media strives to deliver accurate information through careful research. November Editorial . These giant crystals have experienced steady slow growth over the past half a million years. The sinkhole above is visible from the earth's surface. Credit to Isaac Littman via Geologyin.com. These three rock units are the Oneota Dolomite, the New Richmond Sandstone, and the Shakopee formation (also a dolomite). 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. Although the mine is ventilated, making it possible for miners to work … Approximately 2-3 miles (3-5km) under the surface is a giant pool of magma. If a formation doesn’t satisfy all of the three requirements above the formation can not be considered a cave. Known.. As a consequence, without proper equipment, a person cannot survive here for more than 15 minutes. ... specially designed gear, which allows the explorer … Three rock units make up the Prairie du Chien group. That's part of their charm; crystals can be made from just about anything. Caves must also be far enough from the entrance to be able to achieve total darkness. They formed over millions of years in the mineral-rich geothermally heated water that filled the caves.
