Reading Formation
The Reading Formation is a geologic formation in southern England. It dates to the Paleoceneperiod, and is part of the Lambeth Group. It overlies the London Basin and is below the Harwich Formation. The formation is composed of "a series of lenticular mottled clays and sands, here and there with pebbly beds and masses of fine sand converted into quartzite. These beds are generally unfossiliferous."
