Abstract: |
In November and December 2013, one mechanical and four manual geoarchaeological boreholes were drilled by ARCA and The Brislington Community Archaeology Project (BCAP) on the site of St Anne's Well, Brislington, in the city of Bristol, in order to establish the nature of the Holocene stratigraphy. St Anne's Well is located on the narrow flood plain of the Brislington Brook, a tributary of the River Avon. Strata in the borehole cores were described by ARCA geoarchaeologists and members of BCAP. This document reports on the stratigraphy of the boreholes and discusses the archaeological and palaeoenvironmental significance of the sediments encountered. Coarse grained alluvial sands and sandstone gravel was recovered below +6.6m OD in BH1 and below +7.5m OD in BHs 2 and 4. These deposits were derived from reworked colluvium eroded from the Magnotsfield Member which forms the sides of the gorge, through which the Brislington Brook has cut its course to the join the River Avon. Overlying silt/clay and fine sand laminae date to the Early Bronze Age (c.2350-2570 cal BC) and is the first indirect evidence of human activity in the watershed found on the site. After this date approximately 3m of silt/clays accreted on the floodplain. Topsoil has developed conformably within the alluvium in BHs 1, 2 and 5. In BHs 3 and 4 cultural deposits relating to Victorian landscaping were recorded. No in situ organic strata were encountered nor is the alluvial sequence part of the contemporaneous Wentlooge Formation of the central Bristol area. |
