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.
The granite contains secondary minerals like chlorite and epidote apart from the feldspar, quartz and biotite mica. These two minerals are responsible for the clearly visible green shade. The low content of these is not of disadvantage for the good technical characteristics of the granite.
Granite belongs to the plutonic rocks. It solidified when gigantic hot liquid magma bubbles cooled down at a depth of several kilometres under the earth surface. The feldspar crystallised in this case first: In this way, the feldspar could largely take on the predetermined crystal form. It is therefore largely euhedral. The green minerals were generated, still in the depth, by later chemical changes.
