large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
Geodes, mineral veins and layered igneous intrusions.
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
Intrusive igneous
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
Metamorphic rocks that consist of only one mineral and have large interlocking crystals often have a coarse-grained texture. This means that the individual mineral grains are easily visible to the naked eye. Examples of such rocks include quartzite (formed from quartz) and marble (formed from calcite).
Geodes, mineral veins and layered igneous intrusions.
Intrusive igneous rocks commonly have large mineral crystals.
diorite crystals are large and andesite crystals are small
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.
Because while the mineral is found worldwide, large red crystals of rhodochrosite are only found in a few places on Earth, the largest one known to have been found in the Sweet Home Mine near Alma, Colorado
Gypsum is a valuable mineral, as all minerals are. One of its most prominent and beneficial uses is in drywall (sometimes also called gypsum board) thanks to its fire retardant properties and ability to absorb heat energy. The mineral is prevalent and can be found in very large crystals commonly.
Recrystallization. Recrystallization is a process whereby small crystals of one mineral will slowly convert to fewer, larger crystals of the same mineral, without melting of the rock.
They can get very large. In Mexico there were gypsum crystals discovered in an underground mine that measured over 30 feet in length.
Non-foliated metamorphic rock is composed of non-layered visible mineral crystals.
The mineral crystals within them are large enough to see without a microscope.
The presence of hot fluids causes the mineral crystals to become extremely large.
