How old is aquamarine?
Aquamarine is a mineral that forms from the mineral beryl. Beryls can vary in age but typically form in pegmatite veins in igneous rocks. The mineral itself can be found in rocks that are hundreds of millions of years old.
What is another word for mineral veins?
imperative mining
What are large mineral crytals commonly found in?
Geodes, mineral veins and layered igneous intrusions.
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.
Are magnesium veins in caves?
Magnesium veins are not typically found in caves. Magnesium is more commonly found in mineral deposits, such as magnesite or dolomite, which are formed through geological processes. While magnesium may be present in the rocks or minerals of a cave, it is not usually in the form of distinct veins.
Were mineral veins once in solutions?
Yes, mineral veins are often formed when minerals from a solution deposit within fractures or faults in rocks. This usually occurs when mineral-rich fluids flow through cracks and fissures in the Earth's crust and deposit minerals as the fluids cool and/or react with surrounding rock. Over time, this process can lead to the formation of mineral veins.
How do veins form?
pure metals that crystallize from hot water solutions underground often form veins.Veins form when rock collides with another rock and the rock that collide pushes the other rock untill only a little bit of it is left
What happens when blood pools in the veins?
Varicose veins form when blood pools in the veins.
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 mineral occurs in veins?
Copper, gold, silver, to name only three.
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.
What are veins of extremely coarse-grained igneous rocks called?
Veins of extremely coarse-grained igneous rocks are called pegmatites. These veins form from the crystallization of mineral-rich magma, resulting in very large crystals due to slow cooling and high water content. Pegmatites are commonly found in association with granitic rocks.
