this slide quite late, as i already said, on the primary this very earth, in the era of the hadean, archeanat... the conditions were not the same as now, basically they fed, apparently, microorganisms on what was dissolved in water by chemosynthesis, but as soon as it exhausted itself, as soon as the amount of iron in dissolved in the ocean dropped to a certain level, it was necessary to look for something else, photosynthetics appeared, those who learned to use the energy of sunlight for exactly the same thing, in order to get an electron for themselves, and the by-product of this reaction was oxygen, now for us it is synonymous with life. but in general, initially the most terrible poison is an oxidizer of everything, as soon as oxygen began to be released in sufficient quantities, all the remaining iron in the ocean instantly self-oxidized, everyone who oxidized iron also oxidized and this, probably, can be called one of the first global extinctions, when oxygen from some bacteria killed, i don’t know, 90 percent of all the others, as in general, here’s the scheme, who became food, who b

here are the earliest deposits that exist, they belong to such a period as archean, it is about 2.5 billionnd a little older, very early deposits, here is the moment of the formation of the earth, they do not exist, that is, the earliest ones begin in the region of 2.5-3 billion years, in fact, these are rich ores, because they reflect ... very unusual conditions that were then on the earth, on the earth there was no oxygen in the atmosphere yet, therefore the entire cycle of life of the earth and the movement of matter, it was a little different from what is happening today, further, starting from 2.5 billion years and younger, we have such, well , classical objects with an age close to there 1.8 billion years and younger, but most of the deposits, specifically for russia, are certainly distant... well, on active volcanoes, in principle , gold deposition is happening right now and i saw a report, a colleague showed, right in the sublimations of volcanoes he found newly formed gold, that is, the deposit is of course not there yet, but it is being redeposited, and how is it determined that i

on our territory, these are the earliest deposits that exist, they belong to such a period as the archean, it is about 2.5 billion years and a little older, uh, very early deposits, here is the moment of the formation of the earth, they do not exist, that is, the earliest ones begin in the region of 2.5-3 billion years, in fact, these are rich ores, and because they reflect very unusual conditions that were then on the earth, on the earth. there was no oxygen in the atmosphere yet, therefore the entire cycle of the life of the earth and the movement of matter, it was a little different from what is happening today, further, starting from 2.5 billion years and younger, we have such, well , classic objects with an age close to 1.8 billion years and younger, but most of the deposits are for russia, this is certainly the far east, siberia, the urals, and this is the range... well, probably from - 650, but if we take the yenisei crash, theft, yes, well, maybe even from 800 million years to the present, because - modern systems in chukotka, in the far east they are generally determined by an ag
