Where is the dog s head gold generally available? What does kotou gold mean?

In the plate movement, due to the action of strong external forces, the underground gold material is activated, and it is brought below the surface through volcanic eruptions, a few kilometers to dozens of kilometers, forming rocks containing **. In rock-rich areas, rocks often leave a lot of natural gold after oxidation. Wang Yiwen, a researcher, elaborated on the general formation pattern of nuggets:

Gold-bearing source rocks Weathering and denudation, mechanical handling and solution solutions, precipitation, recrystallization, polymerization in the formation of ores. This process is repeated to form a huge "dog's head gold".

Dog's head gold refers to the naturally occurring irregular lump of gold, which is characterized by an impure texture, composed of gold, quartz and other minerals, and the fineness is generally 80-90%; The second is that the block is larger, generally a few hundred grams.

In January 2015, a piece of news that happened in Xinjiang caused a sensation overnight, and suddenly the dream of the poor to get rich was full. It is reported that a Kazakh herdsman picked up a piece of dog's head gold weighing 7,850 grams in Qinghe County, Altay Prefecture, Xinjiang. This is the largest piece of dog head gold found in China, because its artistic value is greater than the value of **, this piece of dog head gold is estimated to be worth more than 100 million.

How the dog's head gold was formed is still a mystery! **The content on the earth is very low, containing 10 grams per ton of gold ore** is already a rich ore, and it is unthinkable to directly enrich it into ko's head gold! Until now, there has been no definite conclusion as to what causes it.

Some people think that it is an extraterrestrial visitor, a golden meteor shower flying from space.

Huma County, Luobei County, Heilongjiang. There has been a gold rush in the Northeast since ancient times, and there are more sand gold and granular gold, and it is a matter of course that there is doghead gold. In the above two counties, a lot of dog's head gold was found.

The probability of picking up doghead gold in these places in China is very high. It should be reminded that the dog's head gold is hard to find, without professional mining knowledge and prospecting experience, it is best not to get involved, if you really pick up the dog's head gold, its artistic value is more precious, do not refine it into pure gold.

There are about 4.8 billion tons** on this earth, of which 100 million tons are in the crust and mantle. Due to the limitations of human science and technology at this stage, theoretically you can dig less than 20 million tons of ** in the earth's crust. However, the cost of investing in gold mining is huge, and it is obviously unaffordable for ordinary people.

Then, I had to hope to pick up a piece of "dog's head gold".

Outdoor Explore Qinghe County Gold Nugget Dog Head Gold Brother Shi will take you to understand what dog head gold looks like? How to find kotou gold?

Dog's head gold is generally near the gold mine, although the name is dog's head gold, but in fact, it is an ordinary natural unpurified gold ore, as long as it is a large enough gold + quartz + other minerals of the aggregate, can be called dog's head gold.

In China, there are Mesozoic magmatic intrusion processes in the Altay region of Xinjiang, Zhaoyuan in Hunan, Shandong, Yanshan Mountains and other places, and they are all the most important production areas.

It has to be where there is primary gold. The ore containing gold elements, after repeated and continuous reduction and precipitation, the small gold nuggets continue to grow, and finally form the doghead gold we see.

Dog's head gold, a gold-rich ore, is a naturally produced, impure texture, large particle and irregular shape of nugget gold.

Ko's head gold is usually composed of natural gold, quartz, and other mineral aggregates.

Some people call it dog head gold because of its resemblance to a dog's head. Some people call it horseshoe gold because of its resemblance to a horse's hoof; However, most of them commonly refer to this natural nugget as dog's head gold.

The formation of doghead gold is due to the enrichment of sedimentary enrichment in the vicinity of gold-rich groundwater and bioaccumulation in the vicinity of gold deposits, when conditions are suitable. There are many stones and impurities in the dog's head gold, and there are potholes, that is, because the environment produced is mostly in the sand particles rich in groundwater, so it is rich in sand particles, and the surface potholes are also due to the inlay of sand stones, and the sand stones fall in the later period, leaving potholes in the shape of sand and stones on the surface.

The case of the discovery of kotou gold.

In the year, the officers and men of the Fifth Detachment who fought in the Xing'an Mountains found a huge "dog's head gold" that shocked China. This piece of gold weighs up to a gram and contains more than 70% gold.

On November 25, Xinjiang Altay discovered "dog-headed gold". This piece of "dog's head gold" is about 19 centimeters long and 13 centimeters wide, flattened, and weighs about 1,840 grams, and was found in Altay, Xinjiang. "Dog's head gold" is a naturally produced, impure texture, large particle size and irregular shape of nugget gold.

On February 5, a herdsman in Qinghe County, Xinjiang, accidentally picked up a piece of dog head weighing about kilograms last week, which resembles a map of China, which is the largest piece of dog head gold found in Xinjiang so far.

Doghead gold is a kind of natural gold nugget containing impurities, mainly from gold-rich ore and gold-rich ore formed during the goldfish geological period. Literally, it can be satisfied, but not pursued. If found, it will be kept as a treasure.

We often say that this kind of dog's head gold is not synthetic, but naturally formed, containing more gold and some large pieces of ore.

The ore produced in this gold mine will not be very large, many of them are small pieces, and even the stones contained in magazines need to go through a certain refining process before they can be refined into the kind we consume daily**, and then used to produce gold and silver jewelry. However, in very rare cases, these mines will appear, very large nuggets with a particularly high gold content in the ore, the appearance is gold, is this ore with high gold content, not 100% gold element, but a slightly higher degree of gold to form gold. In 1909, a gold prospector in Sichuan Province and Yanyuan County was working underground when a 31-kilogram dog's head fell from the top, injuring him.

In 1987, a large gold nugget of heavy grams and grams was found in Konglonggou, Baiyu County, Sichuan Province, which successively broke the weight record of dog's head gold found in China after the founding of New China, and was called a "national treasure".

Doghead gold is generally more close to the mine, and there are some places, remote mountainous areas may also dig doghead gold mines, but this probability is very small. Kotou gold is more likely to be found near gold mines, where the elements are concentrated. There is also a kind of dog's head gold, not real gold, but one, like the color of gold, all kinds of ores, large ores.

Of course, there are also places where the ancients buried gold, and there is also this kind of gold.

Dog's head gold generally refers to some natural metal ores with high gold content, this ore is called doghead gold, and it is usually found near mines. Doghead gold is mainly distributed in placer gold areas. Without professional mining knowledge and mining experience, it is impossible to find it in the ditch, and it is best not to set foot on it, because according to the current laws of China, any cultural relics, mineral deposits, tombs must be handed over to the state.

For doghead gold, it is generally found in Yiyang, Hunan, Baiyu area of Sichuan, Huma County in Heilongjiang, Qaidam in Qinghai, Jiaodong District in Shandong, and Xinjiang and other places; The reason why kobolds are rare is because they have particularly high requirements for geographical location and have strong artistic value.

Where is the dog's head gold generally available? Why is it so rare?

Yiyang area, Hunan. In the area from Yiyang to Anhua, there are many gold deposits, and a lot of dog's head gold has been found since ancient times, among them, in 1983, 6 places with dog's head gold were found, and a total of more than 6,000 grams were found. Since then, many more have been discovered.

It is rare because it is not easy to form.

It generally occurs in some downstream areas with abundant water resources. Because ko's head gold is a gold-rich ore that is naturally produced, it is rare.

Kiss! Hello, happy to answer your <>

Pro, generally the ** per gram of dog's head gold is 1-20,000 yuan. The output of dog's head gold in the world is extremely rare, and it is very difficult to obtain it carefully, and once it is found, it often causes a sensation. According to records (as of 2017), only about 10,000 pieces of doghead gold larger than 10 kilograms have been found in the world.

It takes at least tens of thousands of years for a piece of dog's head gold to form, which not only has artistic value, but also has very blind scientific research value. After the financialization of the dog's head, not only the weight is reduced, but the hardness of the dog's head gold is relatively soft, and it can be scratched with a fingernail, and it is elastic and not easy to break by hand. The voice of the real doghead gold is low, thick, heavy, and there is no aftersound; The fake dog's head gold voice is brittle and not dull, it is generally a dangdang sound, and there is an aftersound.

When the real dog's head gold landed, the old god was not fake** violently. Hope mine can help you <>

If you have any other questions, you can ask me again<>

Summary. Generally, the ** of each gram of dog's head gold is about 1-20,000 yuan.

Generally, the ** of each gram of dog's head gold is about 1-20,000 yuan.

According to the calculation formula of the year's title: 1 * 100 = 1 million, 2 * 100 = 2 million. Therefore, a piece of dog's head gold of about 100 grams can be sold for about 100-2 million yuan.

Let the Zi Dog Head Gold in the world output is extremely rare, very rare, once found in the dust of the dog head gold, often cause a hole to slip sensitive brother stove.

Dog's head gold, also known as "natural gold", because the hole is shaped like a dog's head, horseshoe, etc., it is called "dog's head gold" and "horse hall trembling hooves gold", although the dog's head gold is not pure gold, but because its formation conditions are very harsh, the natural conditions are very rare, the bigger the waiter, the rarer, so the dog's head gold is more expensive than pure gold, once found will be collected by the museum, some of the better quality, the shape of the dog's head gold will even become the "treasure of the town".

Dog's head gold is a very rare natural gold nugget, its collection value is much higher than ** and not the same as ** by gram price, so the dog's head gold is a whole transaction, the bigger, the better the condition, the higher the value, each piece is a unique individual can not be split, so there is no such thing as how much money is a gram.

In fact, the formation of doghead gold is due to the gold-rich groundwater and bioaccumulation near the gold mine, and the enrichment and sedimentation formation under suitable conditions, which has nothing to do with meteors.

There are many stones and impurities in the dog's head gold, and there are potholes, that is, because the environment produced is mostly in the sand particles rich in groundwater, so it is rich in sand particles, and the surface potholes are also due to the inlay of sand stones, and the sand stones fall in the later period, leaving potholes in the shape of sand and stones on the surface.

Because of the similarity between this surface crater and the ablation crater on the surface of meteorites, some people think that the kotohead gold was formed by the fall of a meteor, but it is not. Even in meteorites, the element gold is not enriched, and it is difficult to form gold meteorites with high purity. The fact that the doghead gold comes from a meteor is just a misinformation, and cannot be taken as scientific knowledge, which will mislead people.

There are also many cases of doghead gold found in modern China in China. In 1909, a gold miner in Yanyuan County, Sichuan Province was unfortunately injured by the "stone" falling from the top when he was working underground.

In 1983, Wang Boyu, a farmer in Wudangqiao Village, Nanzheng County, Shaanxi Province, picked up an 810g piece of dog's head gold. It is reported that there is a ravine rich in dog's head gold in Konglong ditch, Baiyu County, Sichuan Province, and in 1987, a large gold nugget was found, and the weight record of dog's head gold found in China since the founding of the People's Republic of China was successively refreshed, which can be called a "national treasure".
