Shale And Slate

Shale - Wikipedia

Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility . [1]

The best known and most commonly seen metamorphic rocks are those produced by Barrovian (also called regional) metamorphism. Beginning with a shale parent, Barrovian metamorphism produces a sequence of metamorphic rocks that goes through slate, and then through phyllite, schist, and gneiss.

Slate vs Shale - What's the difference? | WikiDiff

As nouns the difference between slate and shale is that slate is (uncountable) a fine-grained homogeneous sedimentary rock composed of clay or volcanic ash which has been metamorphosed so that it cleaves easily into thin layers while shale is a shell or husk; a cod or pod. As verbs the difference between slate and shale is that slate is to cover with slate while shale is to take off the shell ...

How to Tell the Difference Between Shale and Slate | Sciencing

Slate is one stage in the metamorphosis of shale, a sedimentary rock, to gneiss, a metamorphic rock. Slate can also form from volcanic rock. In slate, the heated and compacted minerals slowly flow and align themselves perpendicular to the axis of compression, to create "cleavage," which is the tendency of the rock to break along straight lines.
