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 types of rocks are most metallic minerals or metals associated with?
Metallic minerals or metals are commonly associated with igneous rocks, especially mafic and ultramafic rocks such as basalt, gabbro, and peridotite. These rocks have higher concentrations of iron, nickel, copper, and other metallic elements compared to other rock types, making them favorable environments for the formation of metallic mineral deposits.
What is a hydrothermal mineral?
A hydrothermal mineral forms due to the precipitation of minerals from hot, mineral-rich fluids that have circulated through fractures or fissures in rocks deep within the Earth's crust. These minerals typically have distinct crystal shapes and compositions that are influenced by the temperature, pressure, and chemical components of the hydrothermal fluids. Hydrothermal minerals are commonly found in areas with active or ancient hydrothermal systems, such as geothermal fields or some types of ore deposits.
Why do you think are metallic deposits abundant in places where are trenches of volcanoes?
Metallic deposits are often abundant in areas near volcanic trenches due to the geological processes associated with subduction zones. As tectonic plates converge, one plate is forced beneath another, leading to the melting of minerals and the formation of magma. This process can concentrate metals and minerals, which are then brought to the surface through volcanic activity. Additionally, hydrothermal systems associated with these volcanic regions can further deposit metals, enriching the local geology with valuable mineral resources.
Is gamet a metallic?
Gamet, more commonly spelled "garnet," is not a metal; it is a group of silicate minerals. Garnets are typically found in various colors and are commonly used as gemstones and abrasives. They are characterized by their hardness and crystal structure, which distinguishes them from metallic materials. While some garnets may contain trace elements of metals, they are primarily non-metallic minerals.
Sulfide mineral long metallic slender bladed crystals?
The mineral you are referring to is likely acanthite, a silver sulfide mineral that forms long metallic slender bladed crystals. Acanthite is commonly found in hydrothermal veins associated with silver deposits and has a distinct silvery-gray to black color with metallic luster. It is an important ore of silver and is often confused with other silver-bearing minerals such as argentite.
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.
Undersea hydrothermal vent that precipitates a dark cloud of metallic minerals?
This phenomenon occurs when hot, mineral-rich fluids from the Earth's crust meet cold seawater, causing the minerals to precipitate and form a dark cloud. These metallic minerals include compounds of iron, copper, zinc, and sulfur, which contribute to the unique ecosystem around hydrothermal vents.
What types of rocks are most metallic minerals or metals associated with?
Metallic minerals or metals are commonly associated with igneous rocks, especially mafic and ultramafic rocks such as basalt, gabbro, and peridotite. These rocks have higher concentrations of iron, nickel, copper, and other metallic elements compared to other rock types, making them favorable environments for the formation of metallic mineral deposits.
Name the rocks with which non metallic minerals such as petroleum are associated?
Shale
What type of mineral is Chalcopyrite?
Chalcopyrite is a copper iron sulfide mineral with the chemical formula CuFeS₂. It is the most important copper ore and is characterized by its brassy yellow color and metallic luster. Chalcopyrite commonly forms in hydrothermal veins and is often associated with other sulfide minerals. Its primary use is in the extraction of copper for various industrial applications.
What origin does galena come from?
Galena is an ore of lead that is commonly found in hydrothermal veins associated with igneous and metamorphic rocks. It forms through the deposition of lead minerals in these geological environments over time.
What is a hydrothermal mineral?

These minerals typically have distinct crystal shapes and compositions that are influenced by the temperature, pressure, and chemical components of the hydrothermal fluids. Hydrothermal minerals are commonly found in areas with active or ancient hydrothermal systems, such as geothermal fields or some types of ore deposits.
What is an alabandite?
Alabandite is a rare mineral that consists of manganese sulfide. It is typically found in hydrothermal deposits associated with other minerals like sphalerite and pyrite. Alabandite is known for its metallic luster and black color.
Is marble and fossils are non metallic minerals?
fossils are not metallic minerals. marbles are non metallic minerals.
What are 2 uses for metallic minerals?
Metallic minerals are commonly used in the production of metal products such as jewelry, electronics, and machinery. They are also essential for construction materials like steel and cement, making them a critical component in infrastructure development.
What rock contains chalcocite?
Chalcocite is commonly found in copper-rich ores, such as those found in the rocks of hydrothermal veins and in the oxidation zone of copper deposits. It is often associated with other copper minerals like chalcopyrite and bornite.
