FELSIC翻译：石英质的。 了解更多。

Felsic refers to silicate minerals, magma, and rocks which are enriched in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. Molten felsic magma and lava is more viscous than molten mafic magma and lava. Felsic magmas and lavas have lower temperatures of melting and solidification than mafic magmas and lavas.

In a widely accepted silica-content classification scheme, rocks with more than 65 percent silica are called felsic; those with between 55 and 65 percent silica are intermediate; those with between 45 and 55 percent silica are mafic; and those with less than 45 percent are ultramafic.

2017年4月25日 · Felsic lava forms Stratovolcanoes which are tall, steep volcanoes. This is one of the deadliest types of volcanoes for humans. Examples of this type of felsic volcano are Mount Vesuvius and Mount Saint Helens. Both these volcanos are notorious for how explosive and deadly their eruptions where.

The word " felsic " is a term used in geology to refer to silicate minerals, magma, and igneous rocks which are enriched in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. They are usually light in colour and have specific gravities less than 3.

As has already been described, igneous rocks are classified into four categories, based on either their chemistry or their mineral composition: felsic, intermediate, mafic, and ultramafic. The diagram in Figure 3.16 can be used to help classify igneous rocks by their mineral composition.
