African Lapis Lazuli
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
The intense blue rock is composed of one-third each of blue sodalite, white plagioclase feldspar, and the dark silicates amphibole and pyroxene, together with the ore minerals magnetite and ilmenite, which are specular when the light falls obliquely. All minerals are fairly evenly distributed.
Petrogenesis
The rock was formed more than 1.1 billion years ago, when an already solidified magma rock at a depth of several kilometers came into contact with a foreign molten magma penetrating from an even greater depth. This resulted in a chemical transformation of the old rock, which led, among other things, to the formation of the very rare, deep blue mineral sodalite.
