A vein is a deposit of minerals found within a rock fracture that are not part of the host rock. A hydrothermal vein is a vein which is filled with minerals that contain large amounts of water. This water is chemically bound water, meaning that it is part of the chemical formula for that mineral.
A vein of silver forms from a solution by vein minerals that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.
