The Saltworks at Shirleywich are four miles to the E.N.E., and are also in 

 the Keuper marls, but are separated from the extension tract ranging from 

 Stafford, by Stafford and Enson Moors, to the country west of Stone, by 

 an important north and south fault, which throws up the small coalfield 

 of Moddershall, near Stone, and the more important coalfield of Cannock 

 Chase. The throw of this fault is equal to the vertical thickness of the 

 Keuper marls, Keuper sandstones, and Bunter pebble beds or its maxi- 

 mum point, or not less than 1,500 feet. It ranges through Baswich and 

 Sandon, at the latter place being about a mile to the west of the Enson 

 Moor borings. The first of these was made in 1847 in search of coal, 

 and water overflowed at the surface, which is stated to have been used 

 for cooking and drinking, but from the experience of the boreholes since 

 put down by the Stafford Corporation, there is little doubt the water was 

 largely impregnated with salt.
