Excerpt from The Geology of the London District, Being the Area Included in the Four Sheets of the Special Map of London In the present area the strata consist of gravel, sand, loam or brickearth, Clay, marl, limestone, and peat; and they are grouped according to age, position and mode of origin, under names that denote the different geological formations. Examples are found in the Thames Valley Gravels, the Bagshot Sand, the Thames Valley Brickearth, the London Clay, the Boulder Clay (a chalky Clay or marl), the Chalk (limestone), and the Peat which occurs in the Alluvium of the marshlands. These terms indicate for the most part the leading lithological characters, but, as will be learnt from the detailed descriptions, all the formations are subject more or less to changes in composition. The formations represented in the area are tabulated in sequence on Sheet 4; and their order of succession has been proved by observation in pits and quarries, and by the records of wells and borings.
