Agatha

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 microcrystalline rock is mainly composed of glassy, transparent quarzite and very fine-flakey black mica. With a polished surface, fine and shimmery golden metallic crystallites of pyrite become visible.

Petrogenesis

The rock originates in highly argillaceous sandstone that had been deposited on the seabed. Through the load of the massive upper deposits, the rock solidified and, in the process of the later orogeny, was intensely folded by means of high pressure and high temperatures.
