Chinese Black Basalt

Chinese Basalt
In the far north of the southeastern Chinese province of Fujian find the only quarry of this massive calcareous basalt (see pictures).
The quarry, located approximately 2500 meters altitude is reached via a drive through the green tea plantations (Wu Han) of the north of the province
among other renowned.
Basalt solidifies in hexagonal columns (see pictures), which gives a limit on the cross-section of the blocks and thus the reason is that this material as tile
in a maximum size of 100x100 square cm is available.
