Vein is a deposit of minerals linked to nearby firearms and is alien to the surrounding rocks. They are like cutouts in that they fill the voids of surrounding rocks. The veins are formed when mineral components carried by aqueous solution are deposited into a rock mass by deposition. This hydraulic flow is usually due to the circulation of the pelvis

The width of the veins ranges between millimeters and several meters, while the length ranges between tens of meters and kilometers.
