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.
Even though the texture resembles that of granite, the mineral composition of this rock differs significantly from it. It is dominated by feldspar of a grey to white shade, whose 20 mm idiomorphic crystals sometimes glint. These are often surrounded by another form of feldspar, recognisable by its reddish colour, which also forms its own crystals. The black spaces are filled with amphibole. A relatively high content of golden-yellow titanite is considered typical of monzonite.
Magma in a pocket at a moderate depth (5 - 15 km) in the earth's crust differentiated itself in such a way that the parts with a low silicium content solidified separately and thus resulted in plutone, deviating from granite chemism, namely monzonite, an intermediate - and relatively rare - plutonic rock.
