摘要

This report describes the occurrence, extraction and natural hazards related to Triassic gypsum in the Chellaston and Aston-on-Trent areas, south of Derby. A brief historical review of gypsum working from the Middle Ages onward is given. The stratigraphy of the gypsum and Cropwell Bishop Formation in the Mercia Mudstone Group is described. Details of the mines and quarries in the area are presented along with notes about their geology. Geological hazards, related to gypsum workings and natural gypsum dissolution, are noted. This work was undertaken as part of the BGS project to revise the Loughborough Geological Map (Sheet No. 141).
