A cast is when that mold has been filled in with rock or minerals. Carbonization-Carbonization is a process in which the more volatile substances of the organism (hydrogen, oxygen, nitrogen, etc) are removed, leaving behind the carbon.These fossils typically appear as a thin, dark film on the rock. This type of preservation is common among plant fossils. cast is when that mold has been filled in with rock or minerals. Carbonization-Carbonization is a process in which the more volatile substances of the organism (hydrogen, oxygen, nitrogen, etc) are removed, leaving behind the carbon.
Now the fossils have a. white film instead of a black carbon film. Carbonization is the process where only the residual carbon of the organism remains. In nature this usually happens over time when the organism is subject to heat and pressure.here are many ways an organism can become preserved as a fossil. Some of the ways include Casts and Molds, Permineralization, Replacement, and Carbonization Sometimes the fossil is unaltered, meaning it is the actual organism.
