This Appendix has a series of cross-sections of the lithostratigraphy and lithologies using data from a number of ground investigations. The distribution of the cross-sections are shown in Figure A2.1 and listed in Table A2.1. A more detailed map of London is in A2.1. Each set of sections contains a map with the boreholes, a lithostratigraphical cross-section and one or more detailed cross-sections with the lithostratigraphy and boreholes with lithologies. Most of the cross-sections do not include faults.
