Abstract: |
In March 2018, Oxford Archaeology carried out an archaeological watching brief during the excavation of two small test pits within the existing cellar below Staircase 8 at Oriel College, Oxford. The work followed on from earlier test pitting and trenching carried out in 2015 and a borehole transect across Second Quad which was undertaken in 2017. During the 2015 works, possible Oxford Clay was encountered at the base of the stratigraphic sequence, with the lack of overlying gravel suggesting that it had been truncated by a feature within the projected alignment of the putative ditch of the primary burh. However, terrace gravel was encountered in both test pits at approximately the same elevation as the top of the gravel observed during the borehole transect and the earlier test pits and trenching, which suggests that the feature encountered during the 2015 works is more likely to be discrete rather than linear. No dating evidence was recovered from the fairly homogeneous silty clay deposits which overlay the gravel, but it is possible that they correspond with the sequence of medieval occupation observed in the previous phases of work. As with the earlier observations, no evidence for the post-glacial brickearth which overlies the gravel terrace was revealed, which may suggest that these deposits are filling negative features. In one of the test pits, the silty clay deposit had been truncated by a deposit of limestone rubble in a sandy gravel matrix which may have represented the rubble core of an earlier wall, although the extent of this deposit was not revealed. |
