Can shale change into slate

Answer 1

From depth of burial by continual sediment deposition from above, or from compressional stress from tectonic plate collisions, shale is metamorphosed into slate over periods of millions of years. During this compression, the clay minerals making up the shale decompose as they become unstable in the high pressure environment, and their chemical components are gradually transformed into minerals that are more stable in the newly forming higher pressure environment. A more stable high pressure mineral is mica, consisting of flat individual crystals. The mica minerals form in the shale and align themselves at right angles to the direction of the pressure producing a metamorphic rock layering known as foliation. The foliation in slate creates cleavage planes that will bear no relationship to the original bedding planes found in the parent rock, shale.

Answer 2

Mudstone is changed into slate when it has intercourse with shale and then is heated and pressurized. It is truly a sight to watch two rocks get it on.

P.S. By get it on, I really mean have sex.

Answer 3

Shale is transformed into slate by the process of metamorphism. shale will go under high temperatures and pressures to create slate.

Answer 4

Shale is metamorphosed into slate over millions of years. It takes compression from tectonic plate collisions or continual sediment deposition to do so.

Answer 5

The process is called prograde metamorphism.

Answer 6

Slate is a metamorphic rock created when shale is subjected to the heat and pressure of volcanic activity.

Answer 7

When shale is subjected to high temperatures and pressures, it can be metamorphosed into slate.

Answer 8

Yes. Slate is metamorphosed shale or mudstone. The metamorphoses is caused by heat and pressure from depth of burial or plate collisions.
