They are known locally as clunches and underclays and were at one time supposed to represent the soil that produced the vegetation from which the coal was formed, but are now considered by many authorities to be of estuarine origin.
The Estuarine clays of Great Britain--with the possible exception of the Jurassic deposits in Northamptonshire and Lincolnshire--are of minor importance, but in some countries they form a valuable source of clay.
Estuarine deposits partake of the nature of both fluviatile and marine beds, according to their position relative to the river from which they originate.

Beneath the Barton Clay we find in the north of the Isle of Wight, both in Alum and Whitecliff Bays, a great series of various coloured sands and clays for the most part unfossiliferous, and probably of estuarine origin.
Some members, however, of the series have an estuarine character, and must have been formed within the influence of rivers.
