 abstract={The Grimes Graves flint mine site is situated in south-east England. W. Greenwell carried out here, between 1868 and 1870, the first recorded excavation of a deep shaft to its entire depth (12 m). He correctly deduced that the minefield was of Neolithic date. Greenwell’s recorded observations were supported by twentieth century excavations conducted by the Prehistoric Society of East Anglia (1914), A.L. Armstrong (1923-1939) and R.J. Mercer (1971-1972). Excavations by the British Museum over the period 1972-1976 were undertaken to resolve a number of problems connected with the interpretation of the site, mainly: variations in flint extraction and its dating, chipping floors and flint reduction sequence, and the Bronze Age occupation on the minefield. The survey of the 1972-1974 Chipping Floor and Feature 112 enables us to attempt a reconstruction of the stages and directions of the flint processing. Both chipping floors represent debris from the production of blades for axes and adzes, as well as from preparation of discoidal bifacial knives. Finally the authors discuss the finds of Grooved Ware pottery at Grimes Graves},
