grävprov

A grävprov, often translated as a trial pit or excavation pit, is a fundamental archaeological and geological investigation technique. It involves manually digging a small pit to expose and examine subsurface layers, typically soil and sediment. The primary purpose of a grävprov is to understand the stratigraphy of a site, which refers to the distinct layers of soil and deposits that have accumulated over time.

By excavating a grävprov, archaeologists can identify features such as hearths, postholes, burials, or remnants of past structures. They can also recover artifacts, ecofacts (such as animal bones or plant remains), and samples for dating or environmental analysis. The depth and size of a grävprov are determined by the research questions and the expected depth of archaeological interest.

In geological contexts, grävprovs are used to assess soil composition, groundwater levels, and the presence of minerals or contaminants. This information is crucial for construction projects, land development, and environmental impact assessments. The excavated material is carefully documented and removed, and once the investigation is complete, the pit is usually backfilled to preserve the site. The detailed recording of soil color, texture, and the position of any findings is essential for accurate interpretation.
