Important Metamorphic Rocks

IMPORTANT METAMORPHIC ROCKS . Definition . Ø Slate is an extremely fine-grained metamorphic rock characterized by a slate cleavage by virtue of which it can be readily split into thin sheets having parallel smooth surfaces.. Ø The slaty cleavage is due to parallel arrangement of platy and flaky minerals of . the slate under the dominant stresses operating during the process of metamorphism.

LIMESTONE

Limestone is a very common sedimentary rock of biochemical origin. It is composed mostly of the mineral calcite. Sometimes it is almost pure calcite, but most limestones are filled with lots of other minerals and sand and they are called dirty limestones. The calcite is derived mostly from the remains of organisms such as clams, brachiopods ...

What happens when limestone is subjected to …

2021-1-27 · What happens when limestone is subjected to metamorphism? This occurs when limestone, for example, is subjected to heat and pressure and turns into a more coarsely-crystalline and sometimes banded rock called marble. The soft, clay-rich rock known as shale, when subjected to pressure becomes a harder rock called slate.
