Abstract
Records obtained from trial borings with a combined penetration of over 8000 feet of strata are analysed, and an account is given of the Eocene succession revealed. This ranges from the Lutetian to the Sparnacian, comprising the Bracklesham, Bagshot, London and Reading formations. Their maximum proved thickness is 436 feet. The Chalk next beneath the Eocene is that of the Marsupites Zone except in the most northerly boring, where the Uintacrinus Zone was proved. Evidence is adduced suggesting that local variations in the thickness of the Reading Beds may be due to original irregularities on the surface of the Chalk.Keywords
