  1. The river Tinto

  2. The River Tinto belongs to the basin of the Guadiana, is born in the Saw of Padre Caro and after crossing almost 100 Km comes even it estuary at Huelva where it fuses with the river Odiel.

  3. In the high basin of the River Tinto is located the biggest mining deposit places to sky opened of Europe. The development of the mining industry along the history in this zone has originated a peculiar landscape.

  4. The River Tinto is the only place in the world, both for its chromatic beauty and for its exceptional environmental conditions. The waters characterized principally for being of pH very acid and red.

  5. The River Tinto is the only enclave in the world, both for its chromatic beauty and for its exceptional environmental conditions.The place was chosen by the spatial North American agency FISHNET to study these forms of life, due to the probable similarity between its environmental conditions and those who might give in the planet Mars.

  6. The river takes importance as the contributions received from the reservoir of the Marismillas (Nerva), later it receives contributions of the Rivera del Jarrama and other tributaries, but its high degree of mineral concentration in the top section does that it supports the singularity of its waters.

  7. The border of the river characterize for the absence of a vegetation of developed given bank the marked acidity of the way.

  8. Within municipal term of Berrocal, the natural space expands beyond the river including the whole territory of the term that was affected by the summer fire of 2004 (12.636, ha.) where the Govern of Andalucia develops plans of reforestation and regeneration.

  9. With the declaration of River Tinto like Protected Landscape the aims go to preserve the wealth geomorfologic originated by the mining activity, to support the peculiar characteristics of the waters, to guarantee the displacement of the wild animals among the natural spaces that connect, to preserve the natural existing systems in its territorial area, to regenerate the spaces most degraded

  10. As for the flora and fauna, the management of the new protected area will give special attention to species threatened as the so called heather of the mines (Erica andevalensis), endemic plant of Huelva in danger of extinction, and different varieties of bats that nest in the cavities and channels of the mining place.

  11. The river is characterized by the reddish color of its riverbed and yellow - ocher of its shores, originated by the mining activity from its step along Rock of the Iron. In the shores they present typical structures, result of the cooling of the dross and the mining residues.

  14. River Tinto: A piece of Mars on the Earth

  15. Why NASA is interested to explore and study River Tinto environment? • Using information proceeding from the Mars Global Surveyor, it could have discovered in the equatorial region of the red planet deposits of oxide of iron that originated under a mass of liquid stable water. • Recently the water existence has been confirmed in Mars' subsoil.

  16. A British geologist investigated the deposits of iron (gossan) placed in the surroundings of Ríotinto's locality. • The realized studies allowed to know that these oxides were formed in lacustrine environments by high place contained in iron similar to those who today are observed in the River Tinto.

  17. The river Tinto shares many characteristics with Mars: • Presence of minerals as the jarosita, hematita or limonita, and the goethita. • Extreme conditions, as low concentrations of oxygen or acidity. • Big concentrations of iron and sulphur.

  18. ¿How do the organisms survive in the River Tinto? • The aquatic community is adapted to supportin pH’s low values and high concentrations of metals. • The acidity of the waters provokes the increase in the concentratios of Cu+2 y CuOH+ (toxics). • The community of algae and diatomeas cover the bed of the river and few macroinvertebrates which can be fed on the community of algae. Fungi Acidophilic Black Protists Acidophilic

  19. QuimiolitotroficBacterium : • They provoke the oxidation of the ferrous iron of the pyrite to ferric ion. • The ferric ion controls the pH of the river and protects of the radiation UV. Besides they provide the reddish color of the waters. • They turn the sulphurs in sulphuric acid and sulphate of iron. Euglenoids Acidophilic Diatomeas Acidophilic

  20. TIOBACILLUS It presents anaerobic growth and uses the sulphur like donor of electrons and the ferric ion as aceptor.

  21. LEPTOSPIRILLUM They obtend his energy oxidizing the ferrous ions of the pyrite in ferric. Click here to come back
