Description:
Sumrakov granite is fine grained. Lower parts of the quarry contain grey (blue) granite; the top parts then contain yellow granite, as depicted in Figures 1 to 4. Up to several cm thick ferrous pigmentation is clearly visible along fractures (see Figures 5). Figure 6 shows polished granite. The tested sample was taken from the lower parts of the quarry (the grey variant).
