7 colored earth

The strong chemical alteration of basalt rock led to the formation of saprolite - a loose clayey rock - on the surface, as well as oxides and hydroxides of iron and aluminum.
It is these oxides and hydroxides that influence the color of the soil. iron oxides have shades raging from red to brown, while aluminum oxides produce blue and purple shades.
Since iron and aluminum repel each other, each metal spontaneously comes into colorful stripes.

Silná chemická zmena bazaltovej horniny viedla k tvorbe saprolitu – sypkej ílovitej horniny – na povrchu, ako aj oxidov a hydroxidov železa a hliníka.
Práve tieto oxidy a hydroxidy ovplyvňujú farbu pôdy. Oxidy železa majú odtiene od červenej po hnedú, zatiaľ čo oxidy hliníka vytvárajú modré a fialové odtiene.
Keďže sa železo a hliník navzájom odpudzujú, každý kov spontánne vytvára farebné pruhy.Read more
