SITE IDENTIFICATION AND CORRELATION USING GEOARCHAEOLOGICAL METHODS AT THE CABECO-DO-PORTO-MARINHO (CPM) LOCALITY, RIO-MAIOR, PORTUGAL

Several geoarchaeological techniques have been employed in evaluating an open-air site within a uniform sand matrix, near Rio Maior, Portuga l. Electrical resistivity data, acquired at the Upper Palaeolithic sit e complex of Cabeco do Porto Marinho (CPM), delineated an important ne w occupational locus. This result was confirmed, first by auger testin g which recovered subsurface artefacts, and then by direct excavation. In addition, 107 samples were recovered at the site for magnetic susc eptibility measurements. Comparisons between magnetic susceptibility p rofiles from two loci, including the new area at CPM, show distinctive patterns which allow direct correlation between the occupation areas. These methods provide quick and inexpensive means for investigators t o evaluate new sites or to correlate between and within sites, without resorting to other more time-consuming and expensive techniques.
