Hiilikerroksen

Hiilikerroksen is a Finnish term that translates to "coal layer" or "charcoal layer." It refers to a stratum of organic matter, primarily decomposed wood or plant material that has undergone pyrolysis, a process of heating in the absence of oxygen. This process converts the original organic material into charcoal, a dark, porous substance composed largely of carbon.

In archaeological contexts, hiilikerrokset are significant indicators of past human activity. They are often found at prehistoric settlement sites, hearths, or in association with metalworking activities. The presence of a hiilikerros can suggest the location of ancient fires, cooking areas, or the remnants of a charcoal production site. The thickness and composition of the layer can provide clues about the duration and intensity of the activity that created it.

Analysis of hiilikerrokset can yield valuable information about the environment and diet of past populations. Radiocarbon dating of the charcoal can help establish chronological frameworks for archaeological sites. Furthermore, examining any preserved artifacts or plant remains within the layer can offer insights into the resources used and the types of food consumed. The preservation of hiilikerrokset is often good due to the anaerobic conditions created by the charcoal itself, which inhibits decomposition. Therefore, these layers are crucial for understanding past human-environment interactions.
