Abstract: |
Borehole survey In November 2016, ARCA performed a watching brief on
geotechnical boreholes and trial pits drilled and
excavated by Delta-Simons Environmental Consultants
Limited on Land at Conington Road, Borough of
Lewisham, London. The White Chalk Subgroup bedrock
sub-cropped between +0.55m OD and +8.75m OD. The
Kempton Park Gravel Member was determined to sub-crop at between +6.49m OD and +4.29m OD. The Gravel
is confined to the southern half of the site where it
occupies an ancient channel of the River Ravensbourne.
Heavily oxidised Fine Grained Alluvium overlay the
gravels and was recorded only in one trial pit (TP203) at
higher elevation in the north of the site (+8.01m OD). No
organic remains were recovered. Thin strata of Head
were recorded in the north of the site. The Fine Grained
Alluvium and Head strata were truncated by modern
Made Ground strata. The thickness of the Made Ground
varied from 1.00m to 4.10m.
An assessment of the BGS borehole records in the
environs of the site revealed two boreholes (TQ37NE1551
and TQ37NE1552) that record fine grained strata with
organic material located to the immediate west of the
site. These strata sub-cropped at a lower elevation to the
Kempton Park Gravels on the site and as a consequence
probably do not sub-crop on the site.
It is concluded that the deposits on the site have a low
archaeological and palaeoenvironmental potential and it
is recommended that no further work is required |
