Abstract: |
Geoarchaeological investigations were carried out at the Isis House site in order to: (1) clarify the nature of the sub-surface stratigraphy, and (2) clarify the nature, depth, extent and date of any alluvium and organic/peat deposits. Following the results of the initial deposit modelling exercise, it was recommended that a programme of radiocarbon dating was carried out in order to assess the age of the Peat horizon at the Isis House site in comparison to those already recorded in the area of the Bankside Channel, and to assess the need for subsequent environmental archaeological assessment of the sequence. The results of the deposit modelling indicate that the Isis House site lies towards the main axis of the Bankside Channel: here, a Gravel surface as low as -5m OD is deeper than has been identified elsewhere within the channel. The sequence of Holocene sedimentation overlying the Gravel is similar to that recorded elsewhere within the Bankside Channel, incorporating a horizon of Sand, the silty/sandy Lower Alluvium, Peat, and the clay-rich Upper Alluvium, overlain by modern Made Ground. Here, the Peat is relatively thin, at between 0.4 and 0.6m thick, perhaps indicative of prolonged fluvial activity at this location either preventing the accumulation of peat, or subsequently eroding its surface. The results of the radiocarbon dating indicate that Peat accumulation occurred at the present site during the late Mesolithic/early Neolithic transition, lying within the age and elevation range of the organic deposits at Surrey House, immediately to the east (Batchelor et al., 2012), from where environmental archaeological analysis of a thick Peat sequence has already been carried out. Given the thin nature of the surviving Peat deposits at Isis House, and their contemporary age with the deposits at Surrey House, no further environmental archaeological assessment is therefore recommended. |
