Stones, sandpits and limestone quarries in the Czech Republic

Mrákotín granite is medium up to fine grained. The stone is typically pigmented to different shades of ochre (so called yellow granite), as depicted in Figures 1 to 3. Grey granite without almost any pigmentation is also common (see Figure 4). Figure 5 shows intense reddish-brown colouring of granite that can only be found along fractures in several centimetre thick layers. Figure 6 shows polished granite. The presented results were obtained on grey granite.
