The origin of gold

CONCLUSION ON GOLD’S ORIGIN

Several processes for moving gold nanoparticles dispersed in the silicate crust exist. They range from the lure of gold sulfides and other similar ions, in the absence of chalcophile cations with an enrichment in galena, arsenopyrites or other thiosalts. The setting in motion of the sulphides has the ability to create gold deposits. Subsequent alteration restores reducing the metal.

Another mechanical transport by water may be carried out thanks to the physico-chemical characteristics (surface tension) of gold microparticles. All prospector knows that the finely divided flakes float easily.

At this stage, if one includes the formation glitter conveyed by brooks and rivers, causing nuggets remains legendary. Here we must bring in a spontaneous natural process under certain conditions, accretion of gold itself. Saw the accused siderophilic properties, demonstrated by the alloys that form almost instantly with a metal such as mercury, and the strange surface features it has and its great malleability, it is conceivable that it is easily welded to itself even in geological conditions. The existence of gold crystallized suppose it has passed through the molten state.

The intervention of siderophilic bacteria are in all likelihood another effective way of concentrating the marbling colloidal gold in rocks with hydrothermal flows upward, to the point of making chips.

The reader can perceive the uniqueness of science. Physics, chemistry, biochemistry are but aspects of the same thing, watching our beautiful Nature. What interests us now is to understand that outside of the primary chemical enrichment, which this has been short-circuited by the transfer of the greater mass of gold to the central ferronickel core, d other chemical reactions (ascending hydrothermal fluids) or biochemical (bacteria) make up for this shortage by giving us all the same local enrichment process, allowing the collection of little gold as iron left us.
