Abstract:		 Desk-based assessment of borehole logs. A geoarchaeological desk based assessment was undertaken on land at Ripple East, Worcestershire owned by CEMEX UK Operations Ltd. The work was commissioned by Cotswold Archaeology Ltd in November 2022 and involved the analysis of the logs of 20 geotechnical boreholes and relevant geological literature to investigate the potential for biological and Palaeolithic archaeological remains to be present on the fluvial terraces that cover the site. These terraces are assigned by the British Geological Survey (BGS) to the Holt Heath Sand and Gravel Member and the Worcester Member of the Severn Valley Formation and rest on bedrock of the Mercia Mudstone Group. The Holt Heath Sand and Gravel Member dates from MIS6 to MIS2 and has a complex record of deposition; the Worcester Member is more tightly constrained to MIS2 to MIS1 (Late Devensian); however, the deposits on or near the site have not been chronometrically dated. The assessment revealed that the Holt Heath Sand and Gravel Member rests on a Mercia Mudstone Group bedrock bench at +14±1m OD; and that the Worcester Member lies between +7.65m OD in the south and +11.30m OD in the centre east of the main site also on the mudstone bedrock. The average thickness of the former is 2.4m (5 records) and of the latter 2.54m (12 records). The potential for biological remains (in particular peat) and for in situ Palaeolithic archaeological remains (in particular lithics) to be found in the terrace deposits is believed to be low. However, boreholes WOB7 and BH07/85 on the Worcester Member record fine grained and waterlogged clayey sand and the upper 1-2m of the Member is tentatively postulated as conducive to the recovery of peat or in situ artefacts. The drilling of purposeful geoarchaeological boreholes could significantly enhance the detail of any fine grained biological strata found and provide a means of dating via Optically Stimulated Luminescence.
