B- Metamorphic rocks. metamorphic rocks are formed through the change of igneous and sedimentary rocks. which sandstone and basalt are. metamorphic rocks are also formed through heat and pressure
Metamorphic rocks are the type of rock that has their origin in the transformation of other rocks (sandstone and basalt, for example) due to pressure and temperature. Examples of metamorphic rocks are gneiss (formed from granite), slate (originated from clay) and marble (limestone formation), quartzite (formed from sandstone) and rocks formed from basalt.
The oldest rocks are igneous and metamorphic rocks, which emerged respectively in the Pre-Cambrian and Paleozoic era. These rocks are called crystalline because of the crystallization of the minerals that formed them.
