far east, siberia, the urals, and this is a range, well, probably from 650, if we take just the yenisei krezhaeven from 800 million years to the present, because the modern system in chukotka in... in the far east, they are generally determined by the age there of 50 million years, 60-90, well, yes, by your geological standards, 50 million is, well, even modern, well, on active volcanoes in principle - gold deposition is happening right now and - i saw the report, a colleague showed it right in the sublimates - he found newly formed gold in volcanoes, that is , of course there is no deposit there yet, but it is being redeposited. how is age determined? here lies, well, from the point of view of the average person, a piece of stone, there is a small piece of gold in it, how to determine that this piece, this small piece of gold appeared 850 million years ago, by and large, determining the age exactly when gold was formed is a difficult task , in geology there is such an approach that allows the use of an isotope system, in other words , the radioactive decay of one chemical element into transfo
