large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
Wiki User
∙ 13y ago
Large mineral crystals are commonly found in igneous rocks, such as granite and pegmatite, where slow cooling allows minerals to grow large. Certain metamorphic rocks, like marble and schist, can also contain large mineral crystals due to high pressures and temperatures. Veins and pockets within rocks can sometimes host large crystals as well.

Which large blocky feldspar is found most often in association with large muscovite crystals?
Orthoclase feldspar is commonly found in association with large muscovite crystals. This mineral combination is often seen in pegmatite deposits, where slow cooling allows for the growth of large crystals.
What are large mineral crytals commonly found in?
Geodes, mineral veins and layered igneous intrusions.
Slow cooling of magma results in the formation of?
Slow cooling of magma results in the formation of igneous rocks with coarse-grained textures, such as granite. The slower the cooling process, the larger the mineral crystals that can form within the rock. These rocks are commonly found in the continental crust.
Which mineral commonly forms porphyroblasts?
Garnet is a mineral that commonly forms porphyroblasts in metamorphic rocks. These large, distinctive crystals grow within a finer-grained matrix and are often visible to the naked eye due to their size and different composition compared to the surrounding rock.
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.
Which large blocky feldspar is found most often in association with large muscovite crystals?
Orthoclase feldspar is commonly found in association with large muscovite crystals. This mineral combination is often seen in pegmatite deposits, where slow cooling allows for the growth of large crystals.
Are large crystals found in diorite?
Large crystals can be found in diorite, typically consisting of plagioclase feldspar and amphibole minerals. These crystals are formed from the slow cooling of magma deep within the Earth's crust, allowing for the growth of larger mineral grains.
What are large mineral crytals commonly found in?
Geodes, mineral veins and layered igneous intrusions.
Slow cooling of magma results in the formation of?
Slow cooling of magma results in the formation of igneous rocks with coarse-grained textures, such as granite. The slower the cooling process, the larger the mineral crystals that can form within the rock. These rocks are commonly found in the continental crust.
Are the crystals of a mineral are always the same size?
No, the crystals of a mineral can vary in size depending on factors such as growth conditions and the speed at which the mineral forms. Crystals can range from microscopic to very large sizes, even within the same mineral species.
Which mineral commonly forms porphyroblasts?
Garnet is a mineral that commonly forms porphyroblasts in metamorphic rocks. These large, distinctive crystals grow within a finer-grained matrix and are often visible to the naked eye due to their size and different composition compared to the surrounding rock.
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.
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.
Why is the rhodochrosite Colorado's state mineral?
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
Why are exceptionally large mineral crystals found in pegmatite?
Exceptionally large mineral crystals are found in pegmatite due to the slow cooling rate of the magma that formed them, allowing more time for the crystals to grow to a larger size. Pegmatites also have a high concentration of volatile elements, which can contribute to the formation of large crystals.
A mineral specimen has very large crystals what is the best explanation for how this happend?
Large crystals in a mineral specimen typically form when the mineral has enough time and space to grow without being obstructed by nearby crystals. This often occurs in environments with slow cooling rates or low levels of impurities, allowing the crystals to grow to a considerable size.
What class of rock is hornblende?
Hornblende is a mineral commonly found in igneous and metamorphic rocks. It belongs to the amphibole group of minerals, which are inosilicates with a double-chain structure. Hornblende is dark green to black in color and can form large crystals in certain rock types.
