Geology & landscape
Geological Period: Carboniferous
Description
Area, 15.5 ha. 38.4 ac. Description This operational clay pit lies just to the south of Grimethorpe, six kilometres east of Barnsley. The special interests are within the Coal Measures strata, exposed by the extraction of clay. They include one of the best available exposures of the Top Marine Band Westphalian C, Middle Carboniferous in the Pennines coalfields. It has yielded an anomalous Myalina facies fauna, a shelly fauna which contrasts with the Anthracoceras/pectinoid facies fauna found elsewhere in this area of Yorkshire. The Top Marine Band is the highest Coal Measures marine band in Britain and is the last evidence of normal marine conditions in this country during the Carboniferous Period. A site of considerable scientific interest.
