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.
Rocks are classified by the processes under which they were formed. The differences in formation account for variations in the appearance of the rocks and, with some practice, you can learn to recognize the different types by sight. Metamorphic Rocks are rocks that have changed form due to heat and pressure.Metamorphic comes from the Greek words meta and morph. Meta means change and morph means form.etamorphic rocks were once sedimentary, igneous or even other metamorphic rocks that have been changed by heat and pressure.
