[edit] Geotechnical data
Geotechnical information such as borehole and test-pit logs can provide a first ‘look’ at the deposits. These logs are made by geotechnical contractors for non-archaeological purposes, but often record colour, texture, organic matter and inclusions (usually relatively non-specific). They also usually record the presence of ‘made ground’ and the depth to natural. However, the quality of data for archaeological purposes is variable and the location and density of boreholes or test pits may not be that required by the archaeologist.
Geotechnical survey can of course be supplemented by geoarchaeological auger or test pit survey. The depth of such investigations needs to be appropriate to the sedimentary environment being studied, and in turn this dictates method. Systematic investigation of this sort can help identify areas of accumulation and erosion in order to pinpoint where buried cultural remains may be located, and conversely where they are unlikely to have developed or to have survived.
