1 After your inspection, you can purchase a treatment plan, in which a company will come out once a year and either do preventative treatments or check/replace monitoring bait stations. 2  The cost for this varies, but could be anywhere from $150 to $300.
Metamorphic Rocks. Any rock (igneous, sedimentary, or metamorphic) can become a metamorphic rock. If rocks are buried deep in the Earth at high temperatures and pressures, they form new minerals and textures all without melting.If melting occurs, magma is formed, starting the rock cycle all over again. the temperature and pressure conditions (metamorphic environment) in which the rock was formed. 2  the composition of the parent, or original unmetamorphosed, rock. 3  aids in the interpretation of the platetectonic setting in which the metamorphism took place. 4  aids in the reconstruction of the geological history of an area.
How Are Metamorphic Rocks Formed. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure. They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks. Sometimes, metamorphic rocks are formed when rocks are close to some molten magma, and so get heated up. Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
