gneiss
Slate is a foliated metamorphic rock.
It is called Non-foliated.
A non-foliated contact metamorphic rock is called a hornfels. Hornfels is called so because of its exceptional toughness and texture both reminiscent of animal horns.
The two classifications of metamorphic rock are foliated and non-foliated:1. Foliated metamorphic rock such as gneiss display banding and regrouping of its mineral constituents as a result of enormous pressures and heat. The banding forms perpendicularly to the direction of pressure. The pressure is usually related to tectonic plate collisions. Schist is another type of foliated rock that exhibits thin layering of micaceous minerals, once again due to pressure and heat. The difference between these two types of foliated rock lies in the rock from which they were derived.2. Non-foliated metamorphic rock such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks.Metamorphic rock can also be classified as regional (from broad processes such as plate tectonics) or contact (from proximity to an invading heat source).
The geologist could see that the metamorphic rock was non foliated as it did not contain aligned minerals in bands.
Marble.
Schistose Structure metamorphic rocks are known as foliated metamorphic rock.
Quartzite, marble, and metabasalt are non-foliated metamorphic rocks..................................... i like dots
foliated
Yes, slate is a foliated metamorphic rock formed from the sedimentary rock shale.
The metamorphic rock, slate, is considered foliated.
A foliated metamorphic rock forms when crystals combine and form visible bands

i'm not sure there are "main" Metamorphic rock types
Yes. Gneiss is a foliated metamorphic rock.
