Portland Grove Whitbed
Location:
Quarried at Jordans Quarry, Portland, Dorset.
Geology:
This appeared to be a fine-grained sedimentary limestone. Light creamy-white coloured matrix containing an abundance (>10%) of highly elongate light-grey (brownish-grey when weathered) coloured fossiliferous material. This material was orientated primarily in one direction which probably represented bedding. These fossiliferous clasts were observed up to 3µm in length. Voidage appeared modest and the fluorescent resin take up appeared high. This sample appeared to be a fairly uniform fine-grained material in which no bedding or linear features other than the fossiliferous material was apparent.
Colour:
Typical Portland colour – creamy/white, although the large concentrations of grey shells can darken the overall colour.
Application:
Cladding
External Paving
Landscaping
