No, not all birthstones are metamorphic rocks. Birthstones can be composed of a variety of minerals and can be classified as igneous, sedimentary, or metamorphic. For example, diamonds (April's birthstone) are formed from carbon under extreme pressure, while others like garnets (January's birthstone) and amethysts (February's birthstone) are minerals that can form in different geological processes. Each birthstone has its own unique origin and characteristics.
no
No. Non-foliated metamorphic rocks include quartzite and marble.
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
Metamorphic Rocks
Any type of rock can become metamorphic.
no
yes, all rocks can form from all others depending on pressure, etc

Slate and marble are examples of metamorphic rocks. Other metamorphic rocks include gneiss, schist, and quartzite. All metamorphic rocks are formed from other rock types.
All sedimentary and igneous rocks
They are all metamorphic rocks.
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
All rock types can be changed through metamorphism.
Metamorphic Rocks
All rocks are solid. Igneous, metamorphic, or sedimentary.
All rocks are in the solid phase of matter.
