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.
What soil is produce more fertile soil igneous or metamorphic?
Igneous soil tends to be more fertile than metamorphic soil because it contains minerals like potassium, phosphorus, and magnesium that are beneficial for plant growth. Metamorphic soil undergoes high heat and pressure, which can decrease its fertility by altering the mineral composition and reducing nutrient availability for plants.
What is a protolith?
A metamorphic rock changes from one form to another by intense heat or pressue. The parent rock, or protolith, is the rock that undergoes change. It can be any rock type, sedimentary, igneous, and even metamorphic.
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.
Igneous rocks are classified based upon their composition and what?
Igneous rocks are classified based on their composition and texture. Composition is determined by the minerals present, while texture refers to the size of the mineral grains in the rock. These classifications help geologists understand the conditions under which the rock formed.
What igneous rock family contains the highest proportion of silica?
Felsic igneous rock contains the highest proportion of silica. Granites are felsic igneous rocks.
HOW does composition layering occur in igneous bodies?
A layered intrusion is a large sill-like body of igneous rock which exhibits vertical layering or differences in composition and texture.
Can igneous rock be felsic?
Yes. Felsic is a term used to describe the composition of some igneous rocks.
When molten rock undergoes crystallization above ground what type of rock results?
Extrusive igneous rock is the result of above ground crystallization.
What can you conclude from the color of igneous rocks?
Their origin, and chemical composition.
How does chemical composition effect igneous rocks?
It affects the color.
What does the term composition mean as it applies to igneous rock?
it can mean two things, (1)mineralogical composition or (2)Chemical composition
Igneous rocks that crystallize from magma and that are composed almost entirely of quartz and feldspar have a composition that is?
Granitic Composition
What does igneous rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
How can igneous rocks be different densities?
Igneous rocks vary greatly in composition and method of formation, resulting in diverse densities.
What characteristics determines the chemical composition of an igneous rock?
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
How Does chemical composition affect the color of igneous rock?
The chemical composition of the rock affects the color of an igneous rockbecause some minerals like quartz change color becasue of t's own
