slate
The foliated metamorphic rock that forms from the sedimentary rock shale under relatively low temperatures and pressures is called slate. Slate exhibits a characteristic foliation, allowing it to break into thin, flat sheets. This transformation occurs due to the alignment of mineral grains, primarily clay minerals, under directed pressure.
The rock you are referring to is shale. Shale is a fine-grained sedimentary rock composed of compacted clay and silt particles. When subjected to intense heat and pressure, shale can undergo metamorphism and transform into slate. This process of metamorphism causes the clay minerals in shale to recrystallize, resulting in the characteristic foliated texture of slate.
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.
Yes, slate is harder than shale. Slate is a fine-grained, foliated metamorphic rock that has undergone more intense heat and pressure than shale, a fine-grained sedimentary rock. As a result, slate is more durable and resistant to erosion compared to shale.
Shale
Yes, slate is a foliated metamorphic rock formed from the sedimentary rock shale.
Slate is formed from the metamorphism of shale or mudstone. This process involves intense heat and pressure which causes the shale to recrystallize into a fine-grained, foliated rock with excellent cleavage properties.
Slate is a foliated (displaying layers or banding) metamorphic rock, and its parent rock was shale or mudstone. Marble is a non-foliated metamorphic rock (no layers or bands) and its parent rock was limestone.
(B)-slate
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.
The parent rock of slate is shale. Slate forms from the metamorphism of shale, which is a sedimentary rock composed of clay and silt-sized particles. The intense heat and pressure during metamorphism cause the clay minerals in shale to recrystallize into a dense, foliated structure characteristic of slate.
hf
yes, slate is metamorphic rock
No. Shale is laminated. Foliations arean allignment of minerals due to increase in temperature and pressure during metamorphism. The laminations in shale however are a result of the plate like nature of clay minerals (more technically known as phyllosilicates) which when deposited lie flat against each other forming the lamina seen in shales.
Schist is a foliated metamorphic rock. It is formed when mudstone, shale, slate, or phyllite are subjected to higher temperature and pressure.
No, shale is a natural form of rock.
Shale can be metamorphosed into slate through the process of low-grade regional metamorphism, which involves heat and pressure causing the minerals within the shale to recrystallize into a fine-grained, foliated structure characteristic of slate.
