It was once believed that the rocks that we now call felsic were rich in silicic acid. This was later disproved, but the outdated term of "acidic rock" still lingers.
Pyroclastic material is more often felsic (acidic) or intermediate, but mafic (basic) pyroclastic material may also occur.
The term felsic des derived from feldspar and silica, which are the primary components of 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.
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.
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.
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.
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.
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
No. Granite is an intrusive felsic rock.
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
When it cools and crystallizes into rock, the rock will be described as felsic igneous rock. Examples of felsic igneous rocks are granite, rhyolite, and pumice.
they are light colors :))
