One day in June 1997, the workers of the 13th gold mining team of the Sigou Gold Mine in Menyuan County, Qinghai Province, were busy at the construction site, at that time, the gold mining equipment was rudimentary, often requiring workers to stare at the chute, and from time to time to clean the stones in the flow trough, the work was not difficult.
On an ordinary day in June, one of the workers found a yellow stone on the chute that looked very much like gold, and the worker obviously did not believe his eyes, because if the stone was really gold, it was a very rare treasure "dog head gold".
Dog head gold, also known as natural gold, is formed in the natural environment, there is no clear definition of dog head gold, people habitually call more than 100 grams of natural gold nuggets as dog head gold.
Excited, the workers dragged it out of the chute, and after inspection, it was indeed a piece of dog head gold, and it was also a very large dog head gold, weighing 6577.5 grams. Although dog head gold is not pure gold, the gold content is less than 100%, and even many are less than 70%, but natural gold is very expensive, although there is no fixed price for dog head gold, but dog head gold is often 2-10 times higher than the price of the same quality gold, but even so, people also have no way to buy, because dog head gold is too rare, once found, it will often be collected by museums as the treasure of the town museum.
How is Dog Head Gold formed?
Over the years, people on the mainland have frequently picked up dog head gold in the wild, for example, in 2015, a herdsman in Xinjiang picked up a piece of dog head gold on the road.
This piece of dog head gold was found on the ground when he was wandering around a mining area in Qinghe County, and when he took it home, he found that the dog head gold weighed 8 kilograms, which was very rare, and some people bought it for 3 million yuan, but the herdsman refused.
In the area of Funiu Mountain in Henan, a dog head gold was also found. In 1988, when Zhang Zhankui, a local villager, was walking along the river near the village, he found a yellow chengcheng thing in the water and picked it up to look like gold. Gold belongs to soft metals, the ancients commonly used to identify gold is to put into the mouth to bite, if you can bite a tooth mark on the gold is real gold, Zhang Zhankui with a mouth bite, found that this is actually real gold, and is still a rare treasure "dog head gold".
Later, this piece of dog head gold was handed over to the local museum, and after evaluation, it was found that this piece of dog head gold weighed 964.5 grams and had a gold content of 93%, which already belonged to the level of "treasure of the town hall".
Seeing this, I believe that many people also want to go to the wild to pick up dog head gold, but in fact, the distribution of dog head gold is regular, not all places have dog head gold, only where these 2 conditions are available, it is possible to form dog head gold.
Golden vein
The main component of dog head gold is gold, if there is no local gold mine or gold vein, there will be no dog head gold nearby. It is worth noting that not only where there is dog head gold in the gold mine, if there is a gold vein in the local area, but the gold vein has a low gold content, the general commercial gold mining company will not mine, but the gold vein with a lower gold content can also produce dog head gold, for example: After the villagers of Funiu Mountain picked up the dog head gold, experts immediately investigated in this generation and found 5 tons of gold mineralization belt, but because the gold content is low, it has not been mined.
Water
The conditions for the formation of gold are very harsh, and the stars we usually see are actually an "alchemy furnace" that can produce other nuclei step by step in the order of the periodic table through nuclear fusion, until the iron nuclei. Gold is located behind iron, and gold cannot be produced in stellar fusion, but is produced by neutron star mergers or supernova explosions, and gold on Earth also comes from.
At the beginning of the formation of the Earth, the temperature of the Earth's surface was very high, the entire Earth was in a state of melting, and the density of gold was large, and it would gradually settle deep into the Earth.
But with the movement of the plates, the gold in the earth's interior will gradually come to the surface of the earth, forming "rock gold", and rock gold is not dog head gold.
When there is flowing water, rock gold will be eroded by the flowing water, dissolved, brought downstream, and gradually deposited in the downstream gentle place, forming "placer gold", the ancient gold diggers are panning for placer gold.
Placer gold is also not dog head gold, only at the right pH, in a suitable environment, placer gold and other minerals condensed together to form dog head gold.
Among them, the longer the formation time of dog head gold, the less impurity content, the higher the gold content, the larger the size, and the more expensive the price.
It is worth noting that not all gold mines, where there is flowing water, will form dog head gold, the formation of dog head gold has a certain degree of accidentality, which is why it is so valuable.
summary
For a long time, people did not recognize the value of dog head gold, but melted it as gold. Even if some people have picked up gold, because the ownership of dog head gold, etc., it also makes people's idea of handing over dog head gold weak, resulting in us not studying dog head gold well, hoping to standardize the ownership of dog head gold in the future, so that more dog head gold can play its own value.
