What name is applied to a coarse grained felsic igneous rock?

The name applied to a coarse-grained felsic igneous rock is granite. It is composed mainly of quartz, feldspar, and mica minerals. Granite is commonly used as a building material due to its durability and aesthetic appeal.


Describe granite using the three characteristics geologists use to classify igneous rocks?

Granite is a coarse-grained igneous rock that is classified as intrusive, meaning it formed beneath the Earth's surface. It consists mainly of quartz, feldspar, and mica minerals, giving it a light color with darker mineral grains. Granite is considered felsic in composition, meaning it has a high silica content.


What is the difference between rhyolite and granite?

Rhyolite is a fine-grained, extrusive igneous rock with high silica content, while granite is a coarse-grained, intrusive igneous rock also rich in silica but with larger crystals. Rhyolite forms from cooled lava flows on the Earth's surface, while granite forms from slowly cooling magma beneath the surface.


Granite is what type of rock?

Granite is a type of igneous rock, which forms from the cooling and solidification of molten materials within the Earth's crust. It is a coarse-grained rock primarily composed of quartz, feldspar, and mica minerals.


What are granite and basalt?

Both are igneous rocks, formed from the cooling and solidification of magma. Granite is a felsic, intrusive igneous rock, with visible well mixed mineral crystals. Basalt is a mafic, extrusive igneous rock, composed of darker mineral crystals, most of which are not distinguishable without the aid of magnification.

Which igneous rock is composed of coarse grained crystals of quartz feldspar and mica?

Felsic igneous rocks (the lightest in color) are comprised mostly of quartz and potassium feldspar. Intermediate igneous rocks (somewhat darker than felsic) are made up of some quartz and potassium feldspar, but mostly plagioclase feldspar.


What are the types of volcanic rocks?

Igneous rocks exhibit three types of textures: coarse grained (intrusive), fine grained (extrusive), and porphyritic (two-stage solidification of mineral constituents). Chemically, they are categorized as felsic, mafic, or intermediate.


Is granite a glassy igneous rock?

No, granite is a coarse-grained igneous rock that is made up of minerals like quartz, feldspar, and mica. Glassy igneous rocks, like obsidian, form when molten lava cools quickly on the surface, resulting in a smooth, glass-like texture.


What are some examples of igneous rocks?

Igneous rocks are generally classified first on the basis of their formation (and therefore their texture) as intrusive or extrusive. Intrusive rocks are solidified from magma under the surface resulting in a visible crystalline texture, and extrusive igneous rocks are solidified from lava at or near the surface, resulting in a small or nearly invisible crystalline texture.Igneous rock can additionally be classified by general chemistry composition as felsic, intermediate, mafic, and ultramafic. Felsic rocks are higher in silica and aluminum. Maficrocks are higher in magnesium and iron.Examples of igneous rock include:pumicebasaltandesitewehrlitemonzoniteanorthositewelded tuffnepheline syeniteaplitewebsteritekimberlitegabbrodioritegranitebasanitetroctolitepegmatitediabasepicritelatitegranodioritetonaliteperidotiteignimbritehornblenditelampophyrephonolitedunitesyenitetachylytemonzogranitetephritegranophyreboniniterhyodacitetrachytecarbonatiteharzburgiteicelanditepyroxenitetrachyandesitefoidoliterhyoliteobsidianscoriaWords used to describe igneous rock or igneous rock typesinclude: ultramafic, mafic, intermediate, felsic, aphanitic, porphyritic, phaneritic, extrusive, intrusive, vesicular, glassy, coarse grained, fine grained, acidic, basic.

How does a granite and a gabbro differ?

Granite is a felsic intrusive igneous rock, its light in colour due to the predominance of acidic magma. while Gabbro is a mafic intrusive igneous rock, its dark in colour as a result of high ferromagnetic composition. They are both coarse grained but only differs basically in chemical composition of the magma.


How do scientists classify intrusive igneous rock?

Scientists classify intrusive igneous rocks primarily based on their mineral composition and texture. The mineral composition is often determined by the types of minerals present, such as quartz, feldspar, and mica, which can indicate whether the rock is felsic, intermediate, mafic, or ultramafic. Texture, which refers to the size and arrangement of the crystals, can be categorized as coarse-grained (with large crystals) or fine-grained (with small crystals), depending on the cooling rate of the magma. Common examples include granite (felsic), diorite (intermediate), and gabbro (mafic).

What is the difference between granite and dolerite?

Granite is a coarse-grained igneous rock composed mainly of quartz, feldspar, and mica. Dolerite, also known as diabase, is a medium- to coarse-grained intrusive igneous rock with a composition similar to basalt. One key difference is that granite forms at shallow depths within the Earth's crust, while dolerite forms at deeper levels.
