The Tiles of Veneguera
On the steep slopes are rocks that appear to have been coloured with delicate brushes ...
How did they get their colour ?
When magma emerges through the tube of the volcano and encounters a humid atmosphere, the atmosphere is saturated with gases known as hydrothermal fluids. These can alter the mineral composition of the surrounding rocks with the greatest effect in the inner wall of the crater.
Here they lie at the edge of the large crater of the Tejeda volcano and the tinted materials are pyroclastic deposits, known as "ignimbritas" which means "burning stone".
The different colours are created by different levels of minerals contained in the fluid.
Many years of erosion means that the interior of the great volcano is now visible and in turn its "Tiles" with wonderful colours.
How many colours do you see?
