How does Gold Naturally Form on Earth's Crust Veins. Instead, most scientists now believe that gold actually came to earth from outer space in large meteorites that have struck the planet over billions of years. In fact, most of the gold on Earth is actually loed in its core where its heavy properties caused it .

The effort to understand the geology of gold was perhaps man's first serious effort at understanding the earth's rocks and minerals. Gold is actually a relatively scarce element on the crust of the earth, but it occurs in trace quantities spread throughout many different kinds of rocks and in many different geological environments.

The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth's surface) and endogenetic (formed within the Earth). The bestknown of the exogenetic ores is alluvial gold. Alluvial gold refers to gold found in riverbeds, streambeds, and floodplains. It is invariably elemental gold and usually made up of ...

ESTIMATES OF GOLD IN THE EARTH'S CRUST Parker (1967) has pointed out the difficulty in estimating the composition of the earth's crust, which forms less than 1 percent of the earth's mass (Aller, 1961). Differences among the estimates given by various authors since Clarke and Washington (1924) are due partly

Answer (1 of 3): The heavy elements that make up the Earth, and us came from the explosion of white dwarfs and massive stars as supernovae. Elements such as iron, titanium and sulfur are produced when white dwarfs exceed the ability of their electrons to support them against their own gravity. Wh...

Weathering of rocks and soil is the primary way that clays and clay minerals form at the Earth's surface today. The weathering process involves physical disaggregation and chemical decomposition that change original minerals to clay minerals; weathering is uneven, and many stages of breakdown may be found in the same clay sample.

During the formation of Earth, molten iron sank to its centre to make the core. This took with it the vast majority of the planet's precious metals such as gold and platinum. In fact, there are enough precious metals in the core to cover the entire surface of Earth with a fourmetre thick layer. The removal of gold to the core should leave ...

Gold is an extremely rare element on Earth. Because it doesn't react with very many other elements, it is often found in its native form in the Earth's crust or mixed with other metals like silver. It can be found in veins underground or in small fragments in sandy riverbeds.

Elements and the 'Big Bang' theory. During the formation of the universe some 14 billion years ago in the socalled 'Big Bang', only the lightest elements were formed – hydrogen and helium along with trace amounts of lithium and beryllium. As the cloud of cosmic dust and gases from the Big Bang cooled, stars formed, and these then grouped together to form galaxies.
