Description

Details

This yellow to buff fine sandstone is from the Wealden Group (Hastings sub-group) of the Lower Cretaceous. Approximately 110 million years old. It exhibits large scale cross bedding indicative of fast flowing tidal currents. It is quite soft , friable and flaggy in places and so is extracted mainly for concreting and building sand. Sandstones higher up the sequence such as the Ardingly Sanstones make excellent building stones. This example is from Philpots Quarry, West Hoathly, West Sussex. Specimens are supplied in labelled card trays.
