Is vein a sedimentary rock?
No, veins are not considered sedimentary rocks. Veins are mineral formations that fill fractures in rocks. Sedimentary rocks are formed through the accumulation and compaction of sediments, such as sand, silt, and clay.
What are green rocks with orange veins called?
long
Where can zinc be found in rocks?
It is found in veins in rocks (where it was deposited hydro-thermally) as the mineral sphalerite.
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.
What are bands of ore that form when minerals dissolved in water and enter cracks in rocks?
veins
What are veins of exermely coarse grained igneous rocks called?
Pegmatitic Intrusions (Viens).
What are veins of extremely coarse grained igneous rocks called?
Veins of extremely coarse-grained igneous rocks are referred to as pegmatites. These veins are formed from the last minerals to crystallize in a cooling magma, resulting in very large crystals. Pegmatites can contain economically valuable minerals such as lithium, beryllium, and rare earth elements.
What are mineral deposits beneath earths surface that are different from the surrounding rocks are called what?
These are called veins
Is fluorite an extrusive rock?
No, fluorite is not an extrusive rock. It is a mineral commonly found in hydrothermal veins associated with igneous rocks. Extrusive rocks are formed from lava cooling on the Earth's surface, while fluorite is usually found in veins deep within the Earth's crust.
What rock forms along cracks or in faults?
Veins or dykes of minerals like quartz, calcite, or pyrite can form along cracks or faults in rocks. These mineral veins are known as 'veins' and are the result of precipitation of minerals from hot fluids circulating within the Earth's crust.
What rocks are copper isolated from?
Copper is primarily isolated from copper ores such as chalcopyrite, bornite, and chalcocite. These ores are typically found in igneous and sedimentary rocks, as well as in hydrothermal veins. Copper can also be found in some metamorphic rocks.
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.
