10 deadly rocks and minerals

We often ask the question whether the ground under our feet will consume us. In fact, more and more insidious than we thought. Throw a stone that you have just picked up ... you can get poisoned. This list contains the ten most toxic and potentially deadly minerals that crystallize in rocks and are dangerously deceptive stone beauty. These stones can cause serious harm to your health even without someone threw them in you.

10. chalcanthite (Chalcanthite)

10 deadly rocks and minerals

Seductive bluestone blue crystals composed of copper, in combination with sulfur and other elements, as well as water. This composition makes the copper, which is essential for the organism, but which become toxic in excessive quantities and in very bio-available crystal. In other words, the copper becomes soluble in water and can be absorbed in large quantities in any plant or animal, rapidly weakening him and then killing due to the fact that the important internal organs stop working. Scientists lovers should never try chalcanthite on salt content, because in this case, they can occur an extremely serious overdose copper. Simple production of this blue mineral crystal kill all the algae in the pond a whole, in addition, these crystals are able to create significant environmental problems. Because of the incredible beauty and rarity of the bluestone, within the geological community had an enterprise engaged in the cultivation of artificial crystals for sale that are advertised as authentic samples.

9. Koloradoit (Coloradoite)

10 deadly rocks and minerals

Koloradoit - a newly discovered crystalline mineral normally found in the veins of magma. This mineral is a compound of mercury telluride is formed during the mercury alloy with tellurium, another extremely toxic and rare metal. Therefore koloradoit represents a double threat toxic for those who dare to take it in hand. The combination of these two elements creates a risk of serious injury when carelessly handling. When heated or chemical changes, this strange mineral highlights the deadly vapor and dust. What is most interesting - this mineral is mined to produce tellurium contained in it. tellurium minerals are also found in combination with gold, but the earlier of such combinations has not been known. By a strange fate would deposits koloradoita developed in Australia during the gold rush of unusual after people realized that the stones of tellurium containing gold, fill the potholes in the roads.

8. Hutchinson (Hutchinsonite)

10 deadly rocks and minerals

Thallium - is grim lead counterpart. This dense, greasy metal similar to lead in their atomic masses, but is even more lethal. Thallium is a rare metal that appears in a very toxic compound consisting of a rather strange combinations of elements. The effects of thallium is even more strange, and include hair loss, serious illness in contact with skin and in many cases lead to death. Hutchinson is dangerous, but a striking mixture of thallium, lead and arsenic. Three toxic metals form a lethal cocktail of minerals, which must be handled with great care. Hutchinson was named in honor of John Hutchinson (John Hutchinson), the famous mineralogist from the University of Cambridge. This mineral can be found in the mountainous regions of Europe, mostly in the ore deposits.

7. Galena (Galena)

10 deadly rocks and minerals

Galena is the primary ore, used for lead production. It is a shiny silver cubes unnatural ideal shape. Despite the fact that lead is usually very flexible, the sulfur content in galena makes it extremely fragile and malleable for chemical treatment. Galena is able to cause serious consequences for the workers and amateur researchers who have worked with him without compliance with safety measures. Work samples may lead to dust inhalation. Workers in mines are at high risk of poisoning from contact with the deadly minerals and dust, formed during the production. After extraction of lead from this mineral creates an ecological threat to human health during processing and purification. Galena has cubic fracture process, and if hit with a hammer, the crystal will collapse into several smaller copies its original shape.

6. Asbestos (Asbestos)

Chrysotile (Chrysotile) and amphibole (Amphibolite)

10 deadly rocks and minerals

Asbestos - it is not an artificial product, however, it is one of the most terrible of minerals on the planet. While other minerals act as toxins because of their chemical composition and accidental poisoning victims of asbestos to the fullest holds a mechanical diversion in human lung. Asbestos refers to all categories of natural minerals and consists of a silica - the most abundant mineral in the world solid, iron, sodium and oxygen. The deposits are composed of asbestos aggregations of thousands of tiny, whiskers, which can become airborne. They can also easily get into your lungs. Carcinogenic effects occur due to permanent irritation of lung tissue, resulting in scarring. asbestos education can be found among any set of siliceous rocks, so the study of these rocks have to comply with the relevant safety rules. Oddly enough, the natural weathering leads to the natural spread of asbestos in the atmosphere. As a result, in the lungs of many people can find a small amount of asbestos fibers.

5. Arsenopyrite (Arsenopyrite)

10 deadly rocks and minerals

Arsenopyrite - it's fool's gold, but with a slight difference. A man, confusing it with gold, will not just be a fool. Equally silly solution is picking up this mineral from the earth during the campaign of his career, and continued use of the hands, which visited this mineral for cooking and eating. Arsenopyrite sulphide is iron and arsenic, which belongs to the same type of minerals as pyrite (fool's gold or iron sulfide), the difference lies in the fact that it contains a heavy addition of arsenic. When attempting heating or any mineral changes, it begins to emit a strong garlic odor of arsenic, which comes from lethally toxic, corrosive and carcinogenic vapors produced in this mineral. Even the treatment of this mineral causes a person in contact with volatile sulfur arsenic salts. It is interesting that arsenopyrite can be determined simply by hitting it with a hammer. As soon as the sparks will fly, you can for a brief moment to feel a strong smell of garlic.

4. Thorburn (Torbernite)

10 deadly rocks and minerals

Thorburn is a mineral from hell. Green crystals formed in the shape of a prism as secondary deposits in granitic rocks and consist of uranium. Formed in the complex reaction between phosphorus, copper, uranium and water, great clusters of crystals often tempted collectors their appearance, so people these minerals were sampled for their collection, arranged on the shelves. If the decay of uranium in Chernobyl was not enough, deadly radon gas, can cause cancer of the lungs, slowly from these beautiful stones. This is the crystal that should be left alone. Thorburn can be found in the granite, so your granite countertop can easily contain traces torbernita. Bright green crystals of the cluster miners are used as indicators of uranium deposits.

3. Stibnite (Stibnite)

10 deadly rocks and minerals

Stibnite is antimony sulfide, however, looks like silver. For this reason, a huge, shiny metallic crystals of this unstable compound used once to tide excellent dishes. However, the crystals in the shape of a sword bring death to all those who have used them. stibnite crystals interspersed with antimony killed a considerable number of people, before it became known that the use of this mineral is one of the worst food poisoning. Even if stibnite samples collected for the collection, they should be treated with great caution, to avoid poisoning. It is recommended to wash your hands after any contact with this mineral. In the mines in Osaka in Japan made the best crystals of stibnite in the world, their size reaches 30 centimeters in length. Most samples stibnite like tiny spikes.

2. Orpiment (Orpiment)

10 deadly rocks and minerals

The only thing that could be worse than most of arsenic is a stone composed of arsenic and sulfur. Lethal and reactive orpiment crystals grow in the form of underground mineral formations, often near hydrothermal sources. Orpiment colors look pretty tempting, but if you take it into the hands of the crystals it will highlight the carcinogenic, neurotoxic arsenic powder. The Chinese have made extensive use of this mineral, as well as cinnabar, but with much more dire consequences. In rastolchonnye samples of this stone fell arrows which were then used against the enemies to poison - a rather clever way of throwing a stone. Orpiment famous because it gives off a strong smell of garlic because of the content of arsenic in it. It can also be scattered into a dangerous powder when exposed to light. This mineral is used as a main component for the manufacture of paint ocher, and probably many of those poisoned by artists who have used it.

1. Cinnabar (Cinnabar)

10 deadly rocks and minerals

Cinnabar (mercuric sulfide) is the most toxic minerals for processing of all existing in the world. The name of the crystal means "dragon's blood". It is from cinnabar ore mined mercury. Formed near volcanoes and sulfur deposits of bright red crystals signal the most terrible danger. Cinnabar is capable of releasing pure mercury or heating during processing, causing convulsions occur in humans, there is a loss of sensitivity occurs and death. In the Middle Ages, and in the late 1700s to be directed to work in the Spanish mines, comprising forming cinnabar it was considered practically a death sentence. Cinnabar is widely used in Chinese history for making decorative dishes for the meal, and of her pieces are also created bizarre carvings, sometimes at the expense of the lives of artisans. Even more incredible is that some of the ancient physicians believed that vermilion contained medicinal properties, and prescribed it to treat certain diseases.
