Can we calculate theoretically, in which areas underlain by gold ore, determine the amount of its reserves in a particular field, to decide whether the cost-effective to build a mining company here?After exploration, drilling deep wells and exploration of mines take years, and more than one thousand dollars.Are there any signs to discern the presence of the Earth's interior in the thickness of the precious metal?Alas, a single universal "recipe" search of gold deposits humanity has not yet invented.Although long thought about the question.
gold ore requires geologist intuition, inspiration, almost art.In one area nuggets and dendrites almost sparkle under their feet, while the other has all the accompanying symptoms, and the rock is not a trace of precious metals.To understand the origin of this issue for the people desired substance allows the study of the processes occurring in the bowels of the planet to a depth of several tens of kilometers.
magmatic activity on the Earth chases cracks and large fissures in the rocks hot solutions that leave the walls of the stone channel sediment from feldspar, quartz, sulfur compounds with different metals.Gold ore, platinum, and silver may also be among them.Nuggets often have impurities of silver.If the white metal more than 25%, a stone called electrum.There are native silver, which contains an admixture of gold.This kyustelity wherein the yellow metal may be up to 10%.The chemical composition of the solution, brought precious metals from the lower layers of the crust to a depth of 5-7 kilometers to several tens of meters, it shows that they need to look in the sulfide and chloride environment.
But this knowledge does not bring us to the bottom line: the search for deposits of gold theoretically.Chloride and sulphide source of many, but not the desired metal is found in any of them.We can assume that we are interested in the substance formed from the alluvial deposits of the ancient seas, buried under a layer of earth many kilometers.There, under the influence of high temperatures and pressures, it was melted into the liquid magma, passed through cracks and faults in the solidified form of ore or nuggets.But this scientific hypothesis does not give us a practical use.
try to go the other way: to determine the list of minerals, which frequently coexists gold ore.Satellites are its other precious metals - silver, platinum, palladium, iridium, ruthenium, osmium and rhodium.Also in close intergrowth with splashes of gold found less noble breed: quartz, argentite, pyrite, galena, adularia, albite, and Amethyst.But the trouble is that these satellites often have no grain of gold and therefore can not guide us in finding the cherished core.
mining gold in Russia for a long time was carried out in alluvial deposits, that is, where it will leach to the surface streams.And as in other countries, to invent new tools and research technology development, we have guns prospector remained trough yes sieve.Fortunately, our open spaces of these deposits is still very much.When they exhausted the Urals, they were discovered vast alluvial accumulations in Siberia and the Far East.
