What typically occurs is that a igneous intrusion enters a local country rock. the water within it rises due to density differences. this fluid is a few hundred degrees celcius and is very rich in metals and quartz. It rises along faults or fractures in the rock until it cools thus forming hydrothemal veins.
What else can I help you with?
Where is fluorite formed?
Fluorite is formed in hydrothermal veins associated with granite and other igneous rocks, as well as in sedimentary rocks and as a primary mineral in some limestones. It can also form as a product of hydrothermal alteration of other minerals such as beryl and topaz.
Where do quartz form?
Quartz typically forms in igneous, metamorphic, and sedimentary rock environments. It is commonly found in veins and pegmatites in igneous rocks, as well as in hydrothermal veins in metamorphic rocks. In sedimentary environments, quartz can be found in sandstone and shale formations.
What are veins of gold found in rock called?
Veins of gold found in rock are typically referred to as gold veins or gold lodes. These are formed when hydrothermal fluids carry gold and deposit it in cracks and fissures within the surrounding rock.
How do hydrothermal deposit form?
Most hydrothermal deposits form from hot, metal-rich fluids that are left during the late stages of the movement and cooling of magma.
What type of rock is antimonite?
Antimonite is a mineral form of antimony oxide. It is typically found in hydrothermal veins associated with other sulfide minerals. Antimonite is not a type of rock, but rather a mineral.
Is there gold in lava?
Gold is not typically found in lava itself, as it is formed from the cooling and solidification of molten rock. However, sometimes gold can be transported by volcanoes in the form of volcanic deposits or hydrothermal fluids that can eventually crystallize into gold veins.
What happens when blood pools in the veins?
Varicose veins form when blood pools in the veins.
Ores may form from what two liquid substances?
Ores may form from magmatic liquids and hydrothermal fluids. Magmatic liquids can crystallize as they cool, leading to the formation of mineral deposits within igneous rocks. Hydrothermal fluids, which are hot, mineral-rich waters, can deposit minerals in veins and fractures in rocks as they cool or react with the surrounding material. Together, these processes contribute to the concentration of valuable metals and minerals in ore deposits.
Brownish mineral form of mercuric sulphide?
Cinnabar is the brownish mineral form of mercuric sulfide. It is commonly used as a source of mercury and as a pigment in various applications due to its vibrant red color. Cinnabar can be found in hydrothermal veins and is often associated with hot springs and volcanic regions.
What is it called when water-rich solutions carrying metallic salts fill cracks and form?
This process is known as hydrothermal mineral deposition, where hot water carrying dissolved minerals seeps into cracks in rocks or other surfaces. As the solution cools and evaporates, the minerals precipitate out and form crystals.
What name is given to the process where hot mixtures of water and dissolved substances react with existing minerals to form minerals?
The process where hot mixtures of water and dissolved substances react with existing minerals to form new minerals is called hydrothermal mineral alteration or hydrothermal alteration. This process commonly occurs in hydrothermal vents or deep in the Earth's crust.
What deep veins drain the forearm?
The deep veins that drain the forearm are the radial veins and ulnar veins. These veins run alongside the radial and ulnar arteries respectively, and eventually join to form the brachial veins. The brachial veins then merge to form the axillary vein, which continues the drainage pathway.
