It is believed that all chemical elements were originally present in the protoplanetary cloud. From it formed: a metal core in the center of the planet and various minerals around it. And although this is only a model, a hypothesis - it dominates as a fundamental one.
Many metals from the interior through plumes (convection currents in the mantle) and volcanism ended up in surface ore deposits or deposits.
And what a word: deposit! Or: native gold. Those. for some reason, in the Russian language, the process of formation of some metals occurs through their birth in the earth, and not through transfer and loss from somewhere.
Maybe this is so, especially when you look at the examples below:
Gold in a quartz vein. It is seen that quartz crystals grew in this conglomerate. But as in a sandwich, there is gold between them. And also in a peculiar form, not like a frozen melt.
I invested articlewith a version about the hollow structure of planets and stars. This is also a hypothesis, although it overturns many of our ideas about the world.
Here you can see that the vein of gold grew like an ice pattern on glass - like a branch of a plant, a fern.
I immediately remembered the testimony of miners and the beliefs of geology that such "branches" and "leaves" in the layers of coal are supposedly 100% evidence that coal is of biological origin. That these are coked deposits of ancient flora.
I have repeatedly written that there is as much sulfur in coals as there is not in any tree or grass. Sulfur concentration is not comparable to biological life. Bituminous and brown coal is of abiogenic origin. These are petrified oil outflows after disasters. And the branches of supposedly ferns - this is how graphite and carbon grow under certain conditions.
Let's go back to gold. Such a picture with the growth of a gold vein, imitating the branch of a plant, is the growth of crystals and can occur either from a melt or from a solution. I am a supporter of the second version. The same explanation is with the formation of crystals of silicon dioxide in granite - from an overheated solution (broth) under pressure or when some parameters change.
The frosty pattern on the window also does not grow just like that - you need a certain temperature on the glass and the presence of moisture in the air. I think it's the same with gold. In the broth, grains of quartz and a "branch" of gold begin to grow when the physical characteristics of the broth change.
Geologically, gold is most commonly found in hydrothermal quartz veins. Those. quartz can be said to have grown from solutions of hydrothermal vents. Probably, gold is the same.
Placer gold in sands and soil is already a product of the destruction of such conglomerates, when streams of water erosion destroyed and washed out this rock.
Gold can crystallize, grow out of solution and into the following forms:
On the left, it has a common structure with quartz crystals. On the right are individual crystalline forms.
Crystalline gold grown by chemical transport. Those. the growth of gold can be recreated in the laboratory.
Other precious metals of the platinum group are also growing:
The conclusion is this: during geotectonic catastrophes on Earth (global extinction of flora and fauna according to geochronology), processes took place that led to the emergence of new deposits of various metals and minerals. I think this is not a gradual process, but associated with rapid catastrophic phenomena in the lithosphere. But what led to such a destabilization of the subsoil?

Before Muhammad, before Jesus, before Buddha, there was Zarathustra. About 3,500 years ago, in Bronze Age Iran, he saw a vision of the one Supreme God. A thousand years later, Zoroastrianism, the world's first great monotheistic religion, became the official faith of the powerful Persian Empire, its fiery temples were visited by millions of adherents. After another thousand years, the empire collapsed, and the followers of Zarathustra were persecuted and adopted the new faith of their conquerors - Islam

Any civilization needs a lot of resources. Including metals. With the volume built on the territory of Europe, Africa, allegedly remaining from the Roman Empire, the level of metal extraction should be comparable to the level of production in the middle of the 20th century. And there is confirmation of this. One of them is the ancient Roman quarry of Las Medulas, Spain
In the first half of the 19th century, a gold rush began in Russia. Merchants and industrialists from all over the country, as well as from abroad, rushed to the Urals to mine gold. It was then that the famous "Big Triangle" was found - a huge nugget worth tens of thousands of the then rubles
