Please further define what you mean by 'crystal rock'.
Marble.

Metamorphic rock
makes the paper turn white. it also makes it stonger
When limestone is under high pressure from overlaying rock layers and is heated by magma it can form marble.
I suppose it could be marble.
It goes into a rock underground and the rock will soon turn back into a regular rock such as the i was talking bout
Marble, an intermediate grade metamorphic rock.
No, limestone is a sedimentary rock that is the basis for marble if it is compressed by millions of years of pressure. Limestone consists of calcium carbonate, CaCO3. Limestone dissolved in slightly acidic water forms the basis of stalactites and stalagmites in limestone caves.
Limestone is created in small warm still waters where shells and other sediments create layer which in time turn into Limestone.
it becomes a shale rock. There is no way that chalk, a form of limestone, can be metamorphosed into shale. It will like limestone change to marble.
By the metamorphosis of limestone, marble is formed. By the thermal decomposition of limestone, quicklime is formed. Which process depends on the temperature and pressure.
