Abstract: |
This report explores the use of portable X-Ray Fluorescence (pXRF) spectroscopy as a survey technique for archaeological prospection. St Algar's Farm was chosen because recent archaeological excavation (undertaken by a community archaeology group) has indicated that cupellation of lead took place in the Roman period. Lead cupellation is known primarily from the recovery of litharge (lead oxide rich material) left behind when lead was oxidised in order to recover silver. Geophysical surveys of the site show the presence of a simple road system, enclosures and buildings. The excavations have found little evidence for either earlier or later activity. The pXRF was optimised to allow rapid determination of lead content of the soil. Each pXRF analysis point was surveyed using a Global Positioning System (GPS) instrument and the combined datasets were interrogated using Geographic Information Systems (GIS) software to reveal spatial variations which could be compared with the data from other survey techniques. |
