Gold nugget introduction and forming process

Introduction

Gold nugget is a kind of gold produced through mining, and of irregular shape.The host mineral aggregate (natural nugget) which is deposited by weathering or glacial caving and transportation, is one of the sources of the formation of large nugget.

Forming process

Gold nugget is a kind of natural gold containing impurities, and more from the rich gold meteor fall, rain formed gold geological period rich gold ore ", this argument is completely wrong. Where a nugget from a meteor? This is not possible. A nugget of gold are mostly produced in the vicinity, such as Aletai, Al Taishan there is gold. If a nugget from a meteor, why nugget appeared in the gold mine near? Don't know to gold meteor near gold? This obviously unreasonable.

In fact, the formation of nugget is rich in gold because gold near water and biological enrichment, the formation of sedimentary enrichment in the conditions for the case, no relationship with meteor. Nugget inside the stone and impurities, and potholes, due to the environment is rich in groundwater in sand, so rich in sand also, due to the bumpy surface sand stone mosaic, sand stone in the late fall, left on the surface of sand stone shape due to erosion pit potholes. The surface of potholes and meteorite on the surface of some similar, some people think that nugget is formed is not falling meteor, even in meteorites. Gold is not rich in this element, and it is difficult to form highly pure gold meteorites.A piece of “gold nugget” about 19cm long and 13cm wide, and weighing about 1.84kg, was found recently in Altai, Xinjiang Uyghur Autonomous Region, China.
