Andesites are dark-coloured and black, display coarse-columnar jointing and sometimes fluidal texture. Total height of exposure benches attains tens of meters. Along the jointing planes in the weathered crust, there appear enigmatic scripts caused by deviations and shifting of semi-chilled lava primary fluid strips.
