Niether. Foliation is a characteristic of metamorphic rocks. Basalt is igneous.
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
Geologists classify rocks based on their origin (igneous, sedimentary, metamorphic), grain size (fine-grained, coarse-grained), mineral composition (feldspar-rich, quartz-rich), and texture (foliated, non-foliated).
The foliated metamorphic rock that forms when shale is subjected to relatively low temperatures and pressure is called slate. Slate is characterized by its fine grained texture and ability to be split into thin sheets.
If the mud has lithified into shale or mudstone, then metamorphosed, the answer would be slate.
Phyllite is an example of a fine-grained foliated metamorphic rock
Slate
Foliated rocks have layers in them. We often refer to the layers as Banding.
Chert is non-foliated. Foliation is a term that is used mainly to describe the appearance or texture of metamorphic rock. Chert is a sedimentary rock, composed mostly of microcrystalline quartz.
Phyllite is a type of metamorphic rock that forms from the metamorphism of slate. It is characterized by its sheen, fine-grained texture, and foliated structure.
Niether. Foliation is a characteristic of metamorphic rocks. Basalt is igneous.
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. It is popular for a wide variety of uses such as roofing, flooring and flagging because of its durability and attractive appearance.
Geologists classify rocks based on their origin (igneous, sedimentary, metamorphic), grain size (fine-grained, coarse-grained), mineral composition (feldspar-rich, quartz-rich), and texture (foliated, non-foliated).
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
No, slate is not magnetic. Slate is a fine-grained, foliated metamorphic rock that is formed from the compression of mudstone and shale. It does not contain magnetic minerals that would make it magnetic.
Metamorphic rock can be coarse grained or fine grained.
