What else can I help you with?
Which material has definite properties and definite chemical composition?
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
What is the chemical composition of the sterol that is present in high levels in most people who have coronary artery disease?
State the chemical composition of the sterol that is present in high levels in most people who belong to the high-risk group.
What are minerals considered to be?
A mineral has a fixed chemical composition, and crystal format. Sometimes we may have two minerals with the same chemical formula - e.g. calcite and aragonite, but differ in crystallization.
What are the advantages of frost wedging?
It helps to breakdown rocks without affecting their chemical composition or altering their minerological properties.
What is the comparison between basalt and granite in terms of their origin and texture?
Basalt is a fine grained VOLCANIC igneous rock of mafic composition typically made up of the minerals olivine, clino-pyroxene and calcium rich plagioclase. It is the product of undifferentiated magma at either constructive or destructive plate margins. Granite is a coarse grained PLUTONIC igneous rock of felsic composition typically made up of the minerals quartz, orthoclase, sodium rich plagioclase and either biotite or muscovite mica. It is the product of a highly differentiated, partial melting in which the felsic components have become a segregated fraction separate from the main subducting plate within a destructive plate margin. The two rocks are very different in colour; basalt is grey-brown whilst granite is pink or pale grey. They are however, both igneous rocks & may be used for construction. Granite is frequently used as the building blocks for houses, basalt is more commonly used for kerb stones.
What has a more felsic composition rhyolite or basalt?
Rhyolite has a more felsic composition than basalt.
Which intrusive and extrusive rocks have the same chemical composition?
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
What is the igneous rock between granite and basalt?
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
The mineral composition of the oceanic crust is similar to the composition of what rock?
The mineral composition of the oceanic crust is similar to the composition of basalt rock. Basalt is a type of volcanic rock that contains minerals such as feldspar, pyroxene, and olivine, which are also commonly found in the oceanic crust.
Which igneous rock has the same chemical composition as basalt but a different grain size?
Gabbro has the same chemical composition as basalt (both are mafic rocks) but differs in grain size. Basalt has fine-grained crystals due to rapid cooling at the Earth's surface, while gabbro has coarse-grained crystals as it cools slowly beneath the surface.
What is the lava composition for surtsey?
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.
Peridotite is composed almost entirely of dark sillicate mineralsits chemical composition is referred to as?
Peridotite is composed almost entirely of dark silicate minerals, primarily olivine and pyroxene. Its chemical composition is referred to as ultramafic, containing high levels of magnesium and iron.
Does rhyolite have a more mafic composition than basalt?
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
What chemical property is most commonly used to classify igneous rock?
The mineral composition (silica content) is the chemical property most commonly used to classify igneous rocks. This can help differentiate between different types of igneous rocks, such as basalt, andesite, and granite.
Is probably closest in chemical composition to the upper mantle?
The Earth's upper mantle is composed mainly of silicate minerals rich in magnesium and iron, such as olivine and pyroxene. Basalt is a type of volcanic rock that is commonly found in the upper mantle and has a similar chemical composition to the rocks in the upper mantle.
What is the composition and appearance of mars surfaces crust?
It has basalt and many others.
What intrusive igneous rock has the same mineral composition as basalt?
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.
