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.
2. Geology Relating to metamorphism. Metamorphic rocks are formed when igneous, sedimentary, or other metamorphic rocks undergo a physical change due to extreme heat and pressure. These changes often produce folded layers and veins in the rocks, and they can also cause pockets of precious minerals to form.See Table at rock.etamorphic rocks are formed when igneous, sedimentary, or other metamorphic rocks undergo a physical change due to extreme heat and pressure.
