pölykerroksen
Pölykerroksen is a Finnish term that translates to "dust layer" or "layer of dust." It refers to a stratum of accumulated dust that can be found in various natural and anthropogenic environments. In geological contexts, pölykerros can represent a time period marked by increased airborne particulate matter, often originating from arid or semi-arid regions or from volcanic activity. These layers can be preserved in sediment cores, providing valuable data for paleoclimatic and paleoenvironmental reconstructions. Analyzing the composition and thickness of a pölykerros can help scientists understand past wind patterns, aridity, and major environmental events.
In archaeological and historical studies, pölykerros can indicate periods of abandonment, neglect, or reduced human activity
