Superheated water forces its way into rock faults. It contains many dissolved minerals which crystallise out when the water cools.
Yes and No, while some metal ores may indeed be vein minerals, not all vein minerals are metal ores and not all metal ores are vein minerals.
Vein minerals can contain deposits of metals and other minerals, and occur in fissures or cracks of rock.
A mine that follows the vein of certain minerals, instead of digging a straight tunnel.
vein minerals form between faults.
Metal deposits that occur in the cracks of rocks.
Vein minerals are those that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.
Yes, vein minerals were once in solution as they form when mineral-rich solutions flow through fractures and cracks in rocks, depositing minerals as they cool and solidify. These minerals can include quartz, calcite, sulfides, and various metal ores.
The minerals formed in narrow channels or slabs of rock are called vein minerals. These minerals are deposited within the fractures of the rock, often in a crystalline form. They can include a variety of minerals such as quartz, calcite, and sulfides.
A vein in rock is a line that contains another mineral besides the larger percentage of what the rock is made up of. A vein, for example, could be a vein of coal in a coal mine. Coal is extracted out of the rock.
A hydrothermal vein is composed of minerals deposited from hot, mineral-rich fluids that flow through fractures in rocks. These minerals often include quartz, calcite, and sulfides such as pyrite. The composition of a hydrothermal vein can vary depending on the temperature, pressure, and chemical makeup of the fluid involved.
earth+volcano+water... also hydro-thermal vein+earth=minerals
An apex vein is the highest point of a vein of minerals to the surface of the earth. "U.S. mining laws say that the holder of the apex of a vein can mine the downdip even if it passes under an adjacent claim." This is from Casey Research.
