Abstract: |
Archaeology South-East (ASE), a division of University College London Field Archaeology Unit (UCLFAU), were commissioned by Berkeley Homes (Southern) Ltd to undertake a geoarchaeological watching brief on land east of the A24, west of Horsham, West Sussex during geotechnical investigations carried out by Geo-Environmental LTD in December 2010. The watching brief and assessment of recorded geotechnical logs has allowed for a reasonably comprehensive assessment of potential at the site. The majority of the development area has no potential whatsoever for the preservation of deeply buried Holocene or Pleistocene archaeology and associated palaeoenvironmental remains. In nearly all cases solid Weald Clay was encountered directly below topsoil. In areas flanking the current watercourse, slope deposits reaching depths of 1.5m were recorded but did not contain either archaeology or contexts suitable for palaeoenvironmental remains. However, two areas remain of unproven interest and both have moderate potential for preserving Holocene alluvial sequences and possible associated palaeoenvironmental evidence. These comprise the immediate edge of the Arun watercourse and the alluvial sequence noted in the northern half of the site at locations WS6, WS7 and WS8. The absence of surviving terrace deposits on the valley sides flanking the current channel must be testament to the poor survivability of such deposits of Weald Clay substrates. Such deposits lack coarse components likely to preserve as identifiable terrace deposits (lacking sand and gravels) and the impervious nature of the clay may lead to higher rates of sediment recycling and entrainment in the fluvial systems during periods of high water charge. These facts and the current mis-fit nature of the small water course occupying a wide valley landform attest to the high energy processes involved in the formation of central Wealden hydrology during the Pleistocene and Early Holocene. |
