  1. wholesale knife jewelry Reasons for the formation of gold:
    about 26 billion years ago in the Taikoo generation. The volcanic eruption put a large amount of gold elements from the cracks in the mantle and the crust, and then depressed through the ocean. Regional deterioration effects to form the initial gold ore source. About 100 million years ago, due to the powerful effect, the crust deformed folds, the folds exposed the sea, and the golden material activated and migrated to form a gold ore field, which we called rock gold.
    In the rock gold -rich zone, many natural gold is often left after rock oxidation. The shallow floor of the surface, after tens of millions of years of weathering and erosion, the rocks became sandy soil. Due to the stable nature of gold, it was dismissed into a single body. During the transportation of river water, due to its large proportion, it was deposited in the steady water of the river, so the sand gold mine was formed.
    The expansion information Before the 19th century, the level of gold productivity in human society was very low. Some people studied that in the history of thousands of years before the 19th century, a total of less than 10,000 tons of gold produced by human beings, such as in the 18th century, Only 200 tons of gold produced in 100 years.
    Due to the discovery of a series of gold resources in the 19th century, the gold output has been greatly improved since then, especially in the 50 years in the second half of the 19th century, the gold output exceeded the previous 5,000 years. Total amount. In 2013, the total gold output around the world was about 2,770 tons.

  2. kleitz 601 market street wholesale jewelry wilmington de 1920 In nature, gold appears in the golden blocks or golden grains, underground ore veins and accumulation layers in the rock. The single quality of gold is solid at room temperature, with high density, softness, light, and corrosion resistance. Its ductility is the highest among known metal.
    Thestream operation, earth formation, volcanic eruption, ancient mountain movement, magma spray, golden elements were sprayed from the ground nucleus and sprayed out of the ground; , Crazy windstorm, landslides, mudslides, flood floods, and stable river sedimentation.
    The expansion information: Gold is very precious because of extremely rare, gold mining costs are very high, many physical characteristics are very good, and they have excellent stability and are convenient for long -term preservation. It has become an important part of the complex mechanism of human society.

  3. stella and dot inspired jewelry wholesale At present, based on the latest research, scientists have shown that the gold, platinum, and some other valuable metals we have in our lives are meteorites from ancient times. Through the use of homogeneous measurement methods, scientists found that these elements were later "added" in the research process of early crustal formation topics. The impact of meteorites on the earth may also bring factors that need water and other life. 4 billion years ago, the earth's large -scale meteorite impact seemed to be closely related to our lives. In real life, the Dade Wedding Ring, the gold necklace on the neck, and even the platinum in the tail gas catalytic exhaust purification device placed on your car. All of these are from a large meteorite impact of 3.9 billion years ago During this period, a large number of meteorites accumulated in the Mainland have gradually formed valuable metals we have used today. Some metals, such as gold, platinum, nickel, tungsten, 铱, etc., attracted by iron at the core of the earth, and after the high temperature environment inside the earth began to work, these elements gradually moved to the core position of the earth and participated in the melting process. Essence Therefore, the source of these valuable metal elements in the crust is unusual. Geologists have also raised some theories to explain this problem. Through related research, it was shown in the original earth from 3.8 billion to 4 billion years ago. The shiny metal we like today, these metals are absorbed into a modern mantle in the process of geological evolution of the earth. This hypothesis has been confirmed in the study of the moon -shaped mountains to a certain extent. In the same period, the ring -shaped mountain formed by the moon can also be promoted. It also shows that during this period of 3.8 billion to 4 billion years ago, during this period, it was during this period. Not only was the earth hit a large amount of space meteorite, but the moon was not spared. The research on the impact of the impact of the early Earth's meteorites that valuable metals originated in the early days have been published in the "Nature" magazine, providing further evidence support for related research. A research team led by Matthias Willbold, the University of Bristol University in the United Kingdom, collects rock samples in the southwest of Greenland. The reason why choosing near Greenland as the sampling point is because geologists believe that there is a rock that participates in the earliest crustal activity on the earth, and this time point should be 4 billion years ago, that is, earlier than the earth was great than the earth was greatly suffered from great greatness. During the period of scale meteorites. Scientists compare these collected rocks with other places on the earth that can represent modern mantle structures. If there is a significant valuable metal element in the former sample, it can be explained to a certain extent that meteorite impact is an important factor. Researchers found significant differences in each rock sample on tungsten isotopes. In this regard, Verbold believes that we can deduce from time to time according to this situation, calculate how many meteorite materials are embedded in geological movements, and the tungsten reputation composition and environment we found today on the earth and the environment at that time. How much connection is there. Through the comparative study of tungsten isotopes in rocks, it is by far the most suitable method of isotope. At the same time, the evidence of global chemistry also illustrates the situation of a large number of meteorites hit the earth 4 billion years ago. Richard Carlson, a scientist at the Carnegie Research Institute in Washington, USA, also uses the same homicide to study the early geological activity composition of the earth. Karson believes that we are currently capable of measure the difference in the difference between the isotopes in the rocks. The use of this method to study the early construction activities of the earth can be said to open a brand new window for related geological researchers. According to the calculation of researchers, the content of about half a percentage point in the mantle is supplemented by these meteorites. This ratio does not sound much, but if the conversion is converted into actual quality, it is the number of 20 divisions of 10? Verbold also believes that all the valuable metals we currently use are from a large amount of meteorite from 3.8 billion to 4 billion years ago. Bringing various elements and conditions for the earth to bring life. The scientist Richard Carson held a different point of view. He believed that the early meteorite's impact on the earth was not a good thing, and it may pose a threat to the formation of the earth's life environment to a certain extent. Meteorite impact may make our earth have high temperatures in the early days, and can inhibit the extremely rare but still atmospheric environment. Although we do n’t know if the early earth was impacted by the birth of meteorites on the birth of life, meteorites may bring water, which has a certain impact on the temperature of the earth's surface and the appearance of the atmospheric environment that is beneficial to life.

  4. retail jewelry boxes wholesale 4.5 billion years ago, when the earth was formed, a high temperature was high enough to melt the fireball of most minerals. Many small celestial bodies in the universe had some metal elements and gold. It was also left. Due to the high density of gold, gold sinks his heart, so the mining mine is now underground.

  5. essential oil jewelry wholesale The collision of the two neutron stars will produce and throw a large amount of elements, and gold is one of them. In my cognition, gold was wrapped inside the earth at the beginning of the formation of the earth.
