Why do ores form vein of equal metals? Gold, silver, iron, etc. why would they clump together underground
In other words, when you find a 'vein' of gold you can stay follow the vein for a long time until its 'tapped'. Why would the planets formation create these vein? Or the planets geological evolution create it?
Answers:
Because much of the earth and rock-forming forces involve heat, magma, hose down, and movement. When rocks shift and move, they create voids into which other fluids will seep, then bring within other materials with them,and build them up. That's where the vein come from, moving rock due to tectonic and magma movements. And, since different minerals have different specific gravities, they'll tend to congregate in indistinguishable areas due to their similar weight and mass. Lighter ones will move up, heavier ones down. And countering forces to sometimes stir them up.

Veins basically are created when you put pressure on different competent rocks. These will crack within different angles and when then sliding apart or together cavities will form. Circulating hydrothermal dampen will then start to precipitate elements it solved while going through the surrounding rock into those cavities. Note that vein are by no means the only places to find ore, nor are they in truth relevant to modern mining.
