Slate is primarily a sedimentary rock, originating from very fine clays deposited in deep water - or at least distant from shore. It is only mildly metamorphosed by heat and pressure. Often a good source of fossils.
Obsidian on the other hand is volcanic glass, generally derived from melting and re-freezing of rhyolite lava
What else can I help you with?
What type of mixture is slate rock?
Slate rock is a homogeneous mixture, specifically a metamorphic rock composed of fine-grained minerals such as clay and mica that have undergone intense heat and pressure, resulting in its unique layered structure and smooth texture.
What is the chemical formula for slate?
There is no specific or universal chemical formula for slate, because slate is formed up of various amounts of varying types of rock such as:QuartzMuscoviteIlliteBiotiteChloriteHematitePyriteApatiteGraphiteKaolinMagnetiteTourmalineZirconFeldsparIn some locations, such as the mountains of Wales, slate also contains iron.Because of the range of diversity of which slate is formed from - there is no universally accurate formula for slate in general.
Is slate shiny or dull?
Slate is typically dull in appearance. It has a matte finish and does not have a shiny or reflective surface.
Is slate grey the same as graphite grey color?
Slate grey and graphite grey are similar colors but have slight differences. Slate grey tends to have more of a blue or green undertone, while graphite grey tends to have a dark, matte finish resembling the color of graphite pencils. Additionally, graphite grey may appear slightly darker than slate grey.
Can you use bleach to clean slate?
It is not recommended to use bleach to clean slate as it can damage the surface and alter its natural appearance. Instead, use a mild detergent and warm water solution to clean slate surfaces effectively.
How do you slate?
Slate is formed when clay is squashed under extreme temperature and pressure under the Earth. You can't make it at home!
Does heat and pressure can change into slate?
yes
Can heat and pressure change the sedimentary shale into slate?
No
What are the examples of ingeous rocks?
Obsidian, Granite, and i believe slate
Can heat and pressure change the sedimentary rock shale into slate?
No
What is another word for obsidian?
Synonyms for obsidian are brunet, charcoal, coal, ebony, pitch, raven, slate, sable, clouded, dusky, and somber. Antonyms for obsidian are white and clean.
Extreme pressure and temperatures can change sedimentary rock into .?
Extreme pressure and temperatures can change sedimentary rock into metamorphic rock. This process, known as metamorphism, involves the alteration of the mineral composition and texture of the rock without melting it. Common examples of metamorphic rocks formed from sedimentary rocks include shale transforming into slate and limestone turning into marble.
What do heat and pressure change shale to?
Heat and pressure change shale into metamorphic rock, specifically slate when exposed to low to moderate levels of heat and pressure, and then further into phyllite, schist, and gneiss as the intensity of heat and pressure increases.
What metamorphic rock does shale and granite turn into?
Shale turns into slate, granite into gneiss.
What happens to slate if the pressure increases?
If the pressure on slate increases, it can lead to metamorphism, resulting in the transformation of slate into a denser rock known as phyllite or schist, depending on the degree of pressure and temperature. This process alters the mineral composition and texture, causing the rock to develop a more pronounced foliation or layering. Additionally, the physical properties of the slate may change, making it more compact and resilient.
What is the formation of slate?
when shale is subjected to heat and pressure, it can be metamorphosed into slate.
What causes shale to change into slate?
Shale changes into slate through a process called metamorphism, which involves heat, pressure, and chemical changes. The heat and pressure cause the minerals in the shale to recrystallize into a denser, more compact form, resulting in the fine-grained texture and foliation characteristic of slate. The composition of the original shale, as well as the intensity and duration of the metamorphic conditions, influence the final characteristics of the slate.
