Rosa Norvegia

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.

Petrography

An unmistakable rock of peculiar beauty. Essentially, it is made of three components which draw out over a vast distance with an astounding uniformity: 
a) salmon-pink to pale pink areas of medium-grain calcite, either in the shape of small lenses or longer strips (up to 30 cm at a maximum width of 7 cm).
b) white, rounded clasts of fine-grain dolomite, measuring on average only 3-10 cm in length. 
c) grey to greenish, often fissured streaks of bright mica (muscovite, phengite, perhaps even phlogopite) and alkaline silicate (chiefly diopside and vesuvianite) between the areas of a) and b), frequently forming blurred boundaries. This texture refers most likely to an ancient, previous conglomerate whose debris has been extensively deformed. 

Petrogenesis

The Norwegian Rose was generated by metamorphosis (rock re-forming) from a magnesium-rich and low-iron content limestone massif. The original rock got into larger depths by tectonic movements of the earth crust and was converted under pressure and temperature into marble during a period of millions of years. Its texture indicates that the original rock has been a chalk conglomerate, the fractures of which were deformed by pressure inside the earth crust and arranged in parallel fibres.
