A question that scientists believe they finally have an answer to. They believe that gold was not formed on earth, but is actually made in space. Scientist believe that gold came to earth by giant meteorites that struck the planet over 200 million years. These meteorites were packed with gold and other metals that bombarded the surface during the formation of the planet and molten iron sank to its center to make the core taking gold and platinum with it. The closer it is to the surface the more recent a meteorite has struck.
Although a diamond can be artificially produced, there is no way to do so with gold and only so much is available to us. Of course some scientist believe that gold mining in outer space may be open to explore in the future, such big ideas are far too expensive to be explored at this moment. Maybe if the supply and demand was high enough, plus prices continuing to climb it could be something to explore and do. Until then we have small-scale miners who remaining searching near the surface.
Water erosion actually helps form gold veins that originally formed millions of years ago. Hot water and pressure combined to melt gold will push more amounts of Gold closer to the surface for us to find. Once it cools those gold veins fill the natural cracks in rocks. Even the microscopic veins are sometimes quite significant and the high-grade deposits can be mined very profitable.
Finding gold is key. Most gold is still floating around in the earth’s center or under the ocean and has still yet to be discovered. Gold can be found pretty much anywhere but to find a significant amount is where they have to find the more active parts of earth. Originally gold that was found by accident, it was just stumbled upon near streams or deposits near hills and mountains. The erosion process near large bodies of water reveals large deposits while streams that cut through rocks have the smaller amounts. Gold is one of the most sought out minerals in the world.
