Poikkileikkausprofiilit

Poikkileikkausprofiilit, often referred to as transverse profiles, are a method used in archaeology and geology to analyze the stratigraphy of archaeological sites or geological formations. This technique involves creating a vertical or near-vertical cross-section through the site, revealing the layers of soil, artifacts, or rock strata in a linear fashion.

The primary goal of poikkileikkausprofiilit is to understand the sequence of events that have occurred at a site over time. By examining the different layers, archaeologists can determine the age and context of artifacts, reconstruct past environments, and identify changes in land use or occupation. In geology, transverse profiles help in studying the structure and history of rock formations, aiding in the interpretation of tectonic activities and sedimentary processes.

The process of creating a poikkileikkausprofiili typically involves excavating a trench along a straight line, recording the depth and composition of each layer encountered. This data is then plotted on a graph or map, creating a visual representation of the site's stratigraphy. The profiles can be used to correlate different parts of a site, identify features such as hearths or walls, and provide insights into the site's chronology and evolution.

Poikkileikkausprofiilit are a valuable tool in archaeological and geological research, offering a detailed and systematic approach to understanding the past. They are particularly useful in complex sites where traditional surface surveys may not provide sufficient information. However, the method requires careful planning and execution to ensure accurate and meaningful results.
