Portland Bowers Basebed
Quarried at Bowers Quarry, Portland, Dorset.
The stone was classified as well as sorted, moderately compacted, clast supported Oosparite Limestone. The clasts were predominantly composed of ooliths, but the mollusc shell fragments and quartz were also present. The matrix was composed of sparitic carbonate and some micritic carbonate. There was a moderate abundance of open voidage space. There was some evidence of sedimentary bedding by the preferred alignment of elongate clasts.
Typical Portland colour, creamy/white, although the large concentration of grey shells can darken the overall colour.
