Over the millions of years as the earth formed and cooled down these fluids rich in elements such as gold penetrated the cracks, fissures and cavities in the earths crust. They are deposited in faults, quartz veins, Doleritic sills, fractures, balsaltic rocks, in fact the deposits could have intruded into any sort of

Gold is not formed on the Earth like diamonds and many other gems and minerals. 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. ... geologically speaking. Most of the original discoveries of gold

How Is Gold Formed Geologically . ... 2020-6-14I read theories that gold was formed from stars going nova after the big bang. Prior to Earths final formation these now ancient meteorsasteroids deposited gold all over the world. Gold would be found closet to the Earths core. As gold is a heavy element and Earths early stages, naturally more gold ...

Gold is collected in a precipitate form and further purified. in lode mining, ores of gold are collected from the source by quarrying rocks with the ore deposits. This is known as the mother lode, geology. A mother lode is the principal vein or zone of veins of gold or

2017-1-17 Gold deposits are formed via a very wide variety of geological processes, but they generally fall into three categories: Lode deposits – a lode can be a deposit of ore that fills a fissure in a rock formation, or a vein of ore embedded between layers of rock. Lodes form through a process called mineralization – when gold
