The excitement of what is the addition to the known is organizing the science into the category of what is the first to the open ended avenue of a chart. To navigate these balances is to understand more than the bone is connected to the elbow singing a song to get along little doggy. Although this has a position it is the puzzle that manufactures the Cantore physics to engage mathematics at evolutions picture to involve the “space” in determination.
Perhaps the mishap to what is earth is lost a dust and ash is an explanation for man. To understand the beach to a shore to state coast to coast is not a sailing vessel with the wings as it’s oars. The row of corn is perhaps at the water of the ground and that is gravity as the drain must not just create rice. To further these connections at more than tissue is not the objective of Cantore arithmetic as that is fact to friction in today’s physics or Nostradamus quest of whose atmosphere has an elephant in their room.
Today the date of May 9, 2023 it is the findings that have excited the word to engage the wild finds as microbial to fossil to state this date as what is the dinosaur in the fantastic marsupial. The time from less “space” to word by the caves has introduced word to a world full of evidence.
the Naica mountain caves
Scientists have extracted long-dormant microbes from inside the famous giant crystals of the Naica mountain caves in Mexico - and revived them. The organisms were likely to have been encased in the striking shafts of gypsum at least 10,000 years ago, and possibly up to 50,000 years ago.Feb 18, 2017

Cave of the Crystals
Cave of the Crystals or Giant Crystal Cave (Spanish: Cueva de los cristales) is a cave connected to the Naica Mine at a depth of 300 metres (980 ft), in Naica, Chihuahua, Mexico. It takes the form of a chamber within the limestone host rock of the mine, and is about 109-metre (358 ft) long with a volume of 5,000 to 6,000 cubic metres (180,000 to 210,000 cu ft).[1]
The chamber contains giant selenite crystals (gypsum, CaSO4 · 2 H2O), some of the largest natural crystals ever found.[2] The largest is 11.40 metres (37.4 ft), with a volume of about 5 cubic metres (180 cu ft), and an estimated mass of 12 tonnes.[1] When not flooded, the cave is extremely hot, with air temperatures reaching up to 58 °C (136 °F)[3] with 90 to 99 percent humidity. This is comparable to temperature records in Death Valley, but with much wetter air. The cave is relatively unexplored because of these factors.[4] Without proper protection, people can only endure approximately ten minutes of exposure at a time.[5]
The cave was discovered in April 2000 by brothers Juan and Pedro Sánchez while drilling in the mine. As of October 2015, the mine had reflooded and the cavern filled once more with the water rich in minerals required for the crystals to grow.
A group of scientists in the Naica Project have been studying these caverns.[6]
Formation of the crystals[edit]
Naica lies on a fault above an underground magma chamber which is approximately 3–5 kilometres (2–3 mi) below the cave. The magma heated the ground water which was saturated with sulfide ions (S2−). Cool oxygenated surface water contacted the mineral-saturated heated water, but the two did not mix because of the difference in their densities. The oxygen slowly diffused into the heated water and oxidized the sulfides (S2−) into sulfates (SO2−
4) that precipitated as anhydrite (CaSO4). When the overall temperature of the cave started to drop below 56 °C (133 °F), the hydrothermal and sedimentary anhydrite crystals dissolved, and gypsum (CaSO4 · 2 H2O) crystals formed.[7] The hydrated sulfate gypsum crystallized at an extremely slow rate over the course of at least 500,000 years, forming the enormous crystals found today.[8]
Discovery[edit]
In 1910, miners discovered a cavern beneath the Naica Mine workings, the Cave of Swords (Spanish: Cueva de las espadas). It is located at a depth of 120 metres (390 ft), above the Cave of the Crystals, and contains spectacular, smaller (1-metre (3 ft 3 in) long) crystals. It is speculated that at this level, transition temperatures may have fallen much more rapidly, leading to an end in the growth of the crystals.[2]
Giant Crystal Cave was discovered in April 2000 by miners excavating a new tunnel for the Industrias Peñoles mining company located in Naica, Mexico,[9] while drilling through the Naica fault, which they were concerned would flood the mine.[10] The mining complex in Naica contains substantial deposits of silver, zinc and lead.
The Cave of Crystals is a horseshoe-shaped cavity in limestone. Its floor is covered with perfectly faceted crystalline blocks. Huge crystal beams jut out from both the blocks and the floor. The crystals deteriorate in air, so the Naica Project attempted to visually document the crystals before they deteriorated further.[6]
Two other smaller caverns were also discovered in 2000, Queen’s Eye Cave and Candles Cave,[6] and another chamber was found in a drilling project in 2009. The new cave, named Ice Palace, is 150 metres (490 ft) deep and is not flooded, but its crystal formations are much smaller, with small "cauliflower" formations and fine, threadlike crystals.[11]
Exploration and scientific studies[edit]
A scientific team coordinated by Paolo Forti, specialist of cave minerals and crystallographer at the University of Bologna (Italy), explored the cave in detail in 2006. To survive and to be able to work in the extreme temperature and humid conditions which prevent prolonged incursion in the crystal chamber, they developed their own refrigerated suits and cold breathing systems (respectively dubbed Tolomea suit and Sinusit respirator). Special caving overalls were fitted with a mattress of refrigerating tubes placed all over the body and connected to a backpack weighing about 20 kilograms (44 lb) containing a reservoir filled with cold water and ice. The cooling provided by melting ice was sufficient to provide about half an hour of autonomy.
Besides mineralogical and crystallographic studies, biogeochemical and microbial characterization of the gypsum giant crystals were performed. Stein-Erik Lauritzen (University of Bergen, Norway) performed uranium-thorium dating to determine the maximum age of the giant crystals, about 500,000 years.[12][13][14] A team led by A. E. S. Van Driessche directly measured the growth rates of these giant gypsum crystals using present-day water of the Naica. They obtained a growth rate of (1.4±0.2)×10−5 nm/s, which is the slowest directly measured normal growth rate for any crystal growth process. Taking into account this rate, the largest crystals would have taken approximately 1 million years to reach their current size.[15]
Penelope Boston (New Mexico Institute of Mining and Technology), speleologist and geomicrobiologist specialist of extremophile organisms, realized sterile sampling of gypsum drillcores by making small boreholes inside large crystals under aseptic conditions. The aim was to detect the possible presence of ancient bacteria encapsulated inside fluid and solid inclusions present in the calcium sulfate matrix from its formation. Solid inclusions mainly consist of magnesium and iron oxy-hydroxide, but no organic matter could be found associated with the solid hydroxides. No DNA from ancient bacteria could be extracted from the solid inclusions and amplified by PCR. Microbial studies on fluid inclusions are foreseen to attempt to evidence the presence of ancient micro-organisms in the original fluid solution in which the crystals developed. At the 2017 meeting of the American Association for the Advancement of Science, researchers, including Dr. Boston, announced the discovery of bacteria found in inclusions embedded in some of the crystals. Using sterile methods, the researchers were able to extract and reanimate these organisms, which are not closely related to anything in the known genetic databases.[16]
Other researches covered the fields of palynology (pollen study), geochemistry, hydrogeology and the physical conditions prevailing in the Cave of Crystals.
Closure[edit]
The cave was featured on the Discovery Channel program Naica: Beyond The Crystal Cave in February 2011.[17] Earlier, it was featured on the History Channel program Life After People, in the episode "Depths of Destruction" of the second season.[18] Additionally, these caves were also featured on the program Angry Planet, in episode 311. Exploration has given credence to the existence of further chambers, but further exploration would have required significant removal of the crystals. As the cave's accessibility is dependent on the mine's water pumps, once mining operations ceased, the caves were allowed to re-flood in October 2015.[16]
If the mining company decides to open another entrance, researchers might again enter to continue their work, according to a February 2019 report.[19][20]
