Geology of the Brackley and Charlton area (SP 53 NE and part of SP 53 NW)

This report describes the geology of the 1:10 000-scale sheets SP 53 NE and part of SP 53 NW (the Brackley and Charlton area) and is read to best advantage in conjunction with those maps. The area of sheet SP 53 NW east of grid line 53, and sheet SP 53 NE were surveyed on the 1:10 560 or 1:10 000-scale by A Horton in 1963, P M Hopson in 1991 and A J M Barron in 1998-99. Mr Horton and Dr Michael J Oates (formerly Peko Petroleum, now of BG Group) also logged a number of sections exposed during the construction of the Brackley bypass in 1986. Dr Oates and Mr H P Powell also provided a number of other section descriptions.
