Shale rocks are formed in the deep waters of swaps, oceans and lakes where the water is still and the fine clay and silt particles are able to settle to the floor. Shale rocks can easily erode due to weathering.
Shale
Shale can metamorphose into slate, which can metamorphose into phyllite, which can metamorphose into schist, which can metamorphose into gneiss.
Slate is metamorphosed shale.
Granite, sandstone, and shale transform into distinct metamorphic rocks under heat and pressure. Granite typically becomes gneiss, characterized by its banded appearance due to the alignment of mineral grains. Sandstone metamorphoses into quartzite, which is known for its hardness and resistance to weathering. Shale, on the other hand, transforms into schist or slate, depending on the degree of metamorphism, with schist displaying a foliated texture and slate exhibiting a more dense and compact structure.
Shale undergoes metamorphism and transforms into slate, then phyllite, followed by schist, and eventually gneiss as heat and pressure increase. This progression represents a sequence of increasing metamorphic grade from low (slate) to high (gneiss) with changes in mineral composition and texture.
The first metamorphic rock to form from shale is slate. With further metamorphosis you get phyllite, then schist, then gneiss.

Shale
Slate, after that it can continue to schist.
Shale becomes schist through the process of metamorphism. Heat and pressure from deep within the Earth cause the minerals in the shale to recrystallize, forming new minerals and textures characteristic of schist, such as aligned grains and distinct foliation. This transformation occurs over millions of years at high temperatures and pressures, converting the original sedimentary shale into a metamorphic rock known as schist.
If you apply shale with intense heat and pressure. you'll get slate. Now just apply intense heat and pressure to the slate an over time you'll get your schist
Schist typically begins as a metamorphic rock called shale, which is composed of clay and other fine-grained sedimentary minerals. Through the process of metamorphism, intense heat and pressure cause the minerals in the shale to recrystallize, forming the distinct foliated structure and mineral composition that characterize schist.
yes, it's slate. it goes from shale to slate to phyllite to mica schist.
Shale typically forms into slate, phyllite, or schist through metamorphism. Each of these metamorphic rocks forms under different temperature and pressure conditions, resulting in varying textures and mineral compositions.
Schist is a foliated metamorphic rock. It is formed when mudstone, shale, slate, or phyllite are subjected to higher temperature and pressure.
The protolith of schist is typically shale or slate, which undergoes metamorphism to form schist. The protolith of anthracite coal is primarily bituminous coal, which is subjected to higher temperature and pressure conditions during metamorphism to convert into anthracite coal.
Mostly: Limestone, Shale, Sandstone and Schist
