The Leighton Buzzard district is of national importance as a source of industrial sand and fuller's earth products, won from the Woburn Sands Formation of early Cretaceous age. This memoir, with the new 1:50 000 sheet it describes, provides a comprehensive modern account of the geology.

In the past, the rocks described in this memoir have been a prolific source of building stone and can be seen in the fabric of many local buildings, including the Oxford colleges. Other natural resources for the construction industry have been worked in the district and the need for these continues. This memoir is a good source of geological background information for planners and civil engineers. The district extends from the eastern suburbs of Oxford to the western outskirts of Aylesbury. Between the towns the area is one of pleasant countryside, with a topography which closely reflects the outcrop geology of Jurassic and Cretaceous rocks. This memoir integrates some of the large body of existing literature with new information gathered during the recent detailed survey of the district.
