Description: | The Lower Tunbridge Wells Sand is a massive, clean, white quartzitic sandstone containing lenses and stringers of small pebbles, mainly vein quartz. It is a finely cross-bedded sandstone and is overlain by a more massive bed. Many of the weathering features present on the cavernous lower part, the rounded nature of the surfaces, the widened joints suggest the sandstone might be calcareous. However, this has never been observed and these features are thought to be due to a combination of water seepage and frost action. The Wealden Series, of which the Lower Tunbridge Wells Sand is part is a series of lacustrine (lake) and deltaic deposits laid down in the northern end of an elongate, subsiding basin, the Anglo-Paris Basin of Cretaceous age. |
