Can any type of rock become another type of rock?
Yes. Kimberlite a rock which under high heat and pressure can become diamond.
Metamorphic rock can become igneous rock by melting and resolidifying. It can also become sedimentary rock through weathering and erosion, deposition and lithification. It can also become a higher grade metamorphic rock. In a few instances, it can also become a retrograde metamorphic rock. Igneous rock can form from any rock type, if the rock type is melted then cools to a solid.
There are many ways a sedimentary rock can become a metamorphic rock depending on the type of environment but in general metamorphism is any process that changes the mineral content/composition and/or microstructure of a rock which is caused by a change in physical conditions that become different then those under which the rock was originally formed. So for either sedimentary or igneous this can be accomplished by changes in temperature, pressure, stress/deformation or metamorphic fluids.
An igneous rock can become a sedimentary rock by undergoing erosion. An example would be Stone Mountain in Georgia. Weathering and erosion wear away at the mountain, and the particles of quartzite that break away from the mountain are carried from streams to the ocean. Over millions of years, the sand will build up in layers, along with other sediments that end up in the same location. After all deposition (depositing of rocks), cementation and…
Sedimentary rocks can undergo metamorphism, turning it into a metamorphic rock. Sedimentary rock can also become melted, becoming magma and then igneous rock. It can also undergo uplift, weathering and than erosion, becoming sediments again. So the answer is any type of rock including staying itself.
Any rock can become a metamorphic rock. All that is required is for the rock to be moved into an environment in which the minerals which make up the rock become unstable and out of equilibrium with the new environmental conditions. In most cases, this involves burial which leads to a rise in temperature and pressure. The metamorphic changes in the minerals always move in a direction designed to restore equilibrium. Common metamorphic rocks include…
