1. In nature, gold exists as a simple substance in gold nuggets or rocks, underground veins and alluvium. Gold, a simple substance, is solid at room temperature, with high density, softness, brightness, corrosion resistance and the highest ductility among known metals.

2./kloc-Before 0/9th century, the level of gold productivity in human society was very low. Some people think that in the thousands of years before19th century, human beings produced less than 10000 tons of gold, for example, only 200 tons in18th century.

According to scientists' calculations, the total gold reserves of the earth are about 4.8 billion tons, of which about 4.7 billion tons are distributed in the core, 86 million tons in the mantle and less than 654.38 billion tons in the crust. More than 99% of the gold on the earth enters the core. This distribution of gold was formed during the long-term evolution of the earth. The crust formed in the early stage of the earth's development is rich in gold, so it can generally represent the Archean greenstone belt composed of early residual crust, especially the combination of mafic and ultramafic volcanic rocks. The abundance value of gold is higher than that of various rocks in the crust, which may become the earliest "source bed" of gold deposits.

Gold is very precious because it is extremely rare, and its mining cost is very high, many physical properties are very good, stability is excellent, and it is easy to preserve for a long time. These characteristics make gold especially favored by human society, and gold has become an important part of the complex mechanism of human society.
