Abstract

The clay mineral, dickite, is a common rock-forming mineral of many Carboniferous sandstones in North Wales and Northern England and of Middle Jurassic sandstones over much of North-East Yorkshire. It occurs as well-shaped authigenic crystals associated with highly altered mineral assemblages, including partly dissolved feldspar which is one of the probable sources of the alumina and silica.
