Placer gold is the ancient and modern history, major deposits in the world gold production, but after thousands of years of mining, ore-rich and more have been exhausted, and now mainly dominated gold mine, gold is produced in the bottom of the riverbed Bay song or low-lying areas, mixed with sand and stone, after washing out of gold. Shakin originated in mine, is due to the gold ore out of the ground, the wind and rain after a long, weathered and cracked rock, lode gold will accompany sediment from sailing down the natural precipitation in the sand stone, sand and gravel in the river bottom or below deposition of gold layer to form alluvial gold. Shakin features are: particle sizes, big as beans, small sand-like shapes. Color due to the level of different fineness, over ninety percent of red yellow slag machine, eight became yellow, green yellow become China located in seven eastern Asia, the Pacific West Bank, the territory is vast, Woyeqianli, mountains aspect slag machine maintenance, beautiful scenery , lake basin Seira its cloth Cinder machine maintenance, extremely magnificent landscapes. More high mountains in western, eastern hilly plains. This vast expanse of the earth and the complexity and diversity of geological features to store a variety of mineral resources has provided a broad space. In addition, the vast land of China, each complete stratigraphic dating from the Archean to the Cenozoic are distributed; from the Archean to the Cenozoic which more than 30 billion years, the earth has experienced a number of Chinese broad and intense magmatic activity, the formation of a variety of types of magmatic rocks are widely distributed throughout the country; China is an important part of the Eurasian continent, is a global crustal movement and tectonic evolution of the product. By plate tectonic perspective, China is located in the southeastern part of the Eurasian plate, the East and the Pacific plate and the Philippine plate necklace, south Indian plate phase. It is in the border regions in mainland China these large plates, and is affected by several different tectonic units, so as to form a variety of minerals to create good conditions for the geological structure. It is for these various factors, which makes China become a mineral resources in the country.
