Is felsic an intrusive or extrusive igneous rock?
It can be either. "Felsic" is not a specific type of rock but a general description of an ingeous rock's composition indicating high levels of silica and alkali feldspars.
What group of rocks does granite belong to?
Granite is classified as an intrusive igneous rock.
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.
Is gabbro a felsic rock?
No, gabbro is not a felsic rock. Gabbro is classified as a mafic rock due to its dark color and high content of iron and magnesium minerals, while felsic rocks are light-colored and have a higher silica content.
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 is a is a felsic rocks?
A felsic intrusive rock is a a type of compressed granite. a good example would be the McTavish monument on mount royal in Montreal. Despite this felsic intrusive rock is not from Montreal.
Is granite a mafic rock?
No. Granite is an intrusive felsic rock.
Is Felsic a Intrusive or Extrusive Rock?
Felsic rocks can be either intrusive or extrusive. Intrusive felsic rocks form underground when magma cools and solidifies slowly, creating large crystals. Extrusive felsic rocks form at the Earth's surface when volcanic lava cools quickly, resulting in fine-grained rocks like rhyolite.
What is rock type?
Granite is classified as an intrusive, felsic, igneous rock.
Is felsic an intrusive or extrusive igneous rock?
It can be either. "Felsic" is not a specific type of rock but a general description of an ingeous rock's composition indicating high levels of silica and alkali feldspars.
What is light colored ofrten intrusive igneous rock containing a high percentage of silica are called?
felsic
What group of rocks does granite belong to?
Granite is classified as an intrusive igneous rock.
Is Rhyolite Porphyry an intrusive or extrusive rock?
Rhyolite Porphyry is an intrusive rock, formed from the slow cooling of magma underground. It is characterized by large crystals (phenocrysts) surrounded by a fine-grained matrix.
Are felsic rocks usually intrusive or extrusive?
Felsic rocks are usually intrusive, meaning they form below the Earth's surface from magma that cools and solidifies slowly. This slow cooling allows minerals such as quartz and feldspar to crystallize and form coarse-grained textures commonly seen in intrusive rocks like granite.
What type of rock is sandstonelimestonemarblegranite?
Sandstone is a sedimentary rock as is limestone. Marble is a non-foliated metamorphic rock and granite is a felsic intrusive igneous rock.
Is felsic magma eruptive?
Not usually. Because it is so viscous, felsic magma does not erupt as easily as mafic magma. While eruptions of felsic magma do occur, most felsic rocks are intrusive, meaning they solidify underground.
Is granite homogeneous of heterogeneous?
heterogeneous Granite is a common widely occurring type of intrusive, felsic, igneous rock which is granular and crystalline in texture. This rock consists mainly of quartz, mica, and feldspar.
