The close-up view of each stone type shows a relatively true image of the crystalline structure and the colouring. This is suitable for grained slabs to a limited extend only. In regard to the colour matching, please take an original sample of the stone from your furniture store as a basis.
This is a limestone consisting largely of microscopic small, lime shell unicellular organisms (Foraminifers) and shell fragments of other fossils. The matrix is criss-crossed by veins of transparent calcite, which can be thin as a hair but also several millimetres thick and then have a decorative character. The larger of these veins contain in most cases brown iron (hydr)oxide limonite.
Lime sludge deposited – together with a rich fossil fauna - at the bottom of a sea. The sediments were compacted to limestone by diagenetic compacting under the load of the covering layers. Over the millions of years the rock broke up under the influence of tectonic tensions. However, the clefts generated by this healed due to deposition of crystalline calcite.
