It has different kinds of chemicals in it
No. Shale is a mixture.
Shale can be dissolved in heated Hydroflouric Acid
== == == == == == The cap rock on a coal bed is usually a sedimentary rock, (i.e. shale sandstone etc.) but not always shale. Slate is a metamorphic rock, usually derived from shale that has been exposed to high pressures and temperatures over very long periods of time. Ways to tell the difference between slate and shale: Slate will have a smooth surface, and possible have light glare at a right angle. Shale will have a dull, sandy surface. Tap them against something hard. Slate will make a "clink" noise, almost like porcelain or ceramic, where shale will make a "thud" sound. Rub it against your teeth. Slate will be smooth, shale will be gritty. == == == ==
When oil shale burns it produces high quantities of ash, and is usually taken to large ash heaps!
Shale is a clastic sedimentary rock formed of clay and silt sized eroded particles that are a result of both physical and chemical weathering. The clay minerals, however are the result of chemical weathering of feldspars.
Shale is a rock not a chemical compound.
No, shale is clastic.
plop in erides limestone sandstone and shale by using weatheriing
Shale is a kind of rock and has a somewhat variable chemical composition. As a mineral, it might be more useful to seek its mineralogical formula or description.
I know that limestone reacts to acid and shale does not. Also Limestone is Chemical sedimentary rock while Shale is Detrail(Spell?)
Decompression and Exfoliation weathering are common in Mica and Shale.

Detrital, this is coming from my Geology textbook.
