![]() ![]() For example, at the cropmark site at Forteviot, chemical transformations can be triggered by organic matter accumulation and increased water retention within prehistoric ditch deposits and can have an effect on the type of magnetic contrast. This study demonstrates that, by focusing on the responses of single archaeological features and assessing their physical and chemical signatures, soil composition and processes involved in the ‘history’ of buried features are of importance in improving our understanding of the reasons behind their detection with geophysical means. Second, the different geophysical results were considered with respect to soil chemical concentrations (total phosphate and multi‐element analysis), texture, pH, conductivity, organic matter content and magnetic susceptibility from archaeological deposits, topsoil and subsoil samples. ![]() ![]() First, a range of geophysical techniques was employed over archaeological targets. systematically tested a combined approach using geophysical and soil characterisation to understand the proxy responses of known archaeological features. The results presented here are part of the first research project that. This article explores the application of geophysical and soil geochemical methods to detect archaeological features in three traditionally ‘difficult’ survey environments in Scotland: wind‐blown sands (Bay of Skaill, Orkney), clay (Chesterhall Parks Farm, Lanarkshire) and glacial drift deposits (Forteviot, Perthshire). ![]()
