Tóm tắt

An electrical resistivity survey of a lacustrine infilled basin in drift (Abbot Moss, N. England) clearly revealed the morphometry and internal structure of the basin. The technique also delimited extensions to the basin, which are buried beneath colluvium outside the present area of peat accumulation. Resistivity drilling has definite advantages over hand boring particularly for deposits formed between deglaciation and the onset of limnic sedimentation, or for sequences containing inpenetrable sand horizons. Geophysical techniques can provide an overall framework and gross stratigraphy of limnic deposits within which more detailed conventional Quaternary studies can be assessed.
