Large crystals with well-formed crystal faces tend to form when?
Large mineral crystals can form when magma is able to cool slowly underground, creating intrusive igneous rock.
What determines the size of the crystals that form in a sample of granite?
Crystal size in igneous rock is predominately a factor of time spent in cooling from lava or magma. Samples with relatively large crystals are the result of the magma having spent a longer amount of time at ideal crystal forming temperatures for each mineral present.
Rocks with large mineral grains are formed from what?
Their texture could be formed from slow-cooling magma, from mineral precipitation and crystallization in pockets or fractures, or from recrystallization during metamorphism.
How was crystal cave formed?
The crystals were formed by hydrothermal fluids emanating from the magma chambers below
Compare the ways in which ironmagnesium minerals and feldspars crystallize from magma?
In Bowen's reaction series, feldspar minerals go through a continuous change of composition, while iron-magnesium groups have an abrupt change of mineral types. When magma cools, the feldspars that form are calcium-rich. As cooling continues, the feldspars react with magma and the feldspar composition changes. The result is a zoned crystal with sodium-rich outer layers and calcium-rich core. For iron-magnesium minerals, when magma starts cooling, a mineral begins to crystallize. However, when the magma temperature drops, a whole new mineral begins to form. The previously formed minerals reacts with the magma and is converted into the new mineral.
What determines the type of mineral formed by cooling magma?
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
What determines the size of a minerals crystals?
The rate at which magma cools determines the size of the mineral crystal.
Large crystals with well-formed crystal faces tend to form when?
Large mineral crystals can form when magma is able to cool slowly underground, creating intrusive igneous rock.
What are two factors affect the type of igneous rock that is formed?
The mineral composition of the magma and the rate at which it cools determines what rock forms.
What determines the size of the crystal that form in a sample of granite?
Crystal size in igneous rock is predominately a factor of time spent in cooling from lava or magma. Samples with relatively large crystals are the result of the magma having spent a longer amount of time at ideal crystal forming temperatures for each mineral present.
Rock formed when magma cools slowly?
crystal
What is factor that affects the size of mineral crystal formed in magma?
The main factor is time spent in cooling and solidifying. More time means larger crystals.
What is the difference between magma and crystal?
Magma is molten rock, the dissolved mineral remains of solid rock. During cooling and solidification, the magma will crystallize into a mass of crystallized mineral components.
Can minerals from from the cooling of magma?
Yes. When magma cools and solidifies, mineral crystals are formed.
What affects th size of crystals formed from magma?
the slower the magma cools the bigger the crystal is
