New Imperial Red
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
Medium size grain granite, which consists of up to 80-85% bright red alkali feldspar. In addition, dark-grey-transparent quartz and, of lesser importance, very little black biotite mica occurs. Such granite types are called alkali feldspar granite and are almost always bright red. They have very little or no black biotite, as all the iron had been used up for haematite (iron ore), which causes the red colouring of the feldspar. Single feldspar crystals only appear pink-coloured due to the lower haematite content.
Petrogenesis
New Imperial Red has been generated, like numerous other Indian hard rocks, during the Pre-Cambrian period, when large-volume magma complexes of granite composition intruded the earth crust and solidified in there. Many of these plutonite types melted again in the border areas and were mixed into so-called migmatite (mixed gneiss types), like for instance Paradiso or Multi-colour. This did not happen in the deposit of the New Imperial Red, which crystallised evenly and remained in the upper earth crust level due to tectonic movements and did not undergo any further metamorphosis. To-day, the rock, weathered free, can be quarried in quarries.
