What else can I help you with?
Is basalt an example of a felsic rock?
No, basalt is not an example of a felsic rock. Basalt is an example of a mafic rock, which is rich in iron and magnesium and typically dark in color. Felsic rocks, on the other hand, are rich in silica and aluminum and are lighter in color.
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.
What crystallizes from an intermediate lava and is moderately gray or green in color?
felsic rock
What color is a gneiss rock?
Granite is felsic on the color index. It is largely composed of potassium feldspar and quartz.
What are two examples of felsic rock?
Granite and rhyolite are examples of felsic rocks. These rocks are generally light in color and rich in minerals like quartz, feldspar, and mica. They are formed from the crystallization of magma with high silica content.
What happens if the percentage of felsic minerals in a rock increase?
If the percentage of felsic minerals in a rock increases, the rock will become lighter in color and less dense. Felsic minerals are rich in silica and aluminum, so the rock may also become more viscous when melted. Additionally, the rock's melting temperature may decrease.
Which rock is most felsic out of rhyolite andesite and basalt?
Rhyolite is the most felsic rock out of rhyolite, andesite, and basalt. Felsic rocks have a higher silica content and are associated with continental crust. Rhyolite is typically light in color and has a high silica content, making it more felsic compared to andesite and basalt.
Where did felsic lava get its name?
The term felsic des derived from feldspar and silica, which are the primary components of felsic rock.
What are the terms felsic and mafic used by geologists to describe?
Geologists use the terms felsic and mafic to describe the compositions of igneous rocks. Felsic rocks are rich in silicon and aluminum, making them lighter in color and less dense. Mafic rocks are richer in magnesium and iron, making them darker in color and denser.
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 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.
What is a felsic intrusive rock?
A felsic intrusive rock is a type of igneous rock that is rich in silica and aluminum minerals. These rocks form from the slow cooling of magma below the Earth's surface, allowing large mineral crystals to develop. Granite is a common example of a felsic intrusive rock.
