Creeton Hard White

A beautiful pale white limestone in appearance with minimal fossil content, Creeton Hard White will bring a touch of warmth and elegance to your home or project.

Petrographic Description and Mineral Examination

Creeton Hard White limestone is pale cream in colour with some grains exhibiting a slightly darker orange colour. The fabric was dominantly Oolitic with a few broken bioclastic fragments visible. Most constitutes appeared to be micritic and held within a sparite cement.

In thin section the stone is dominated primarily of ooliths up to 2mm wide and peloids. Many were seeded with this comprising a fossil fragment or intraclast, and showed a concentric structure.

Composition was micritic with many showing fine iron grains within their texture. Elongate and broken fragments of bivalve fossils were also noted with these often consisting of fibrous calcite with micritic margins.

A low level of compaction has been observed with finer fragments and ooliths infilling between coarser particles. A coarse sparite cement enclosed all the costituents with only very few open pore spaces remaining. Based on the mineralogy identified the limestone has been given the classification of Oolitic Limestone.
