Description

Details

Estuarine sandstone as the name implies was laid down as fine cross bedded deposits at the mouths of rivers. Occasional marine incursions are evident from fossils & ripple bedding. Some of the fine beds are peppered with mica flakes. This example is from the Carboniferous of Derbyshire. Specimens are supplied in labelled card trays.
