Talk:Jarosite

message: FOUND IN 1852 IN THE EL BARRANCO Jaros NASA test that ran water through the Martian jarosite, a mineral found in Almería    OLALLA Cernuda    MADRID .- The key to NASA's announcement that Mars had lakes is one days in jarosite, a mineral almost unknown and the origin of the ravine Jaros (Almería), which demonstrates irrefutably that Martian rocks rose water. For this material is formed, it is absolutely necessary and essential aqueous alteration. If there is jarosite, there was water.    Jarosite is a mineral that was discovered in 1852 by the geologist Breithaupt in the Andalusian Jaros gully, a spot located in the Sierra Almagrera in Almeria. Geologists have found jarosite in places such as Rio Tinto (Huelva), Mazarrón (Murcia), Sierra Gorda (Chile) or Burra Burra (Australia), but mine is the type locality almeriense this material.    Mars missions and the Mars Pathfinder and Mars Global Surveyor detected the possible presence of this mineral in the red planet, scientists suggested that it would be a major mineral surface alteration of volcanic rocks on Mars.    Now, Opportunity has been able to analyze the rock 'Captain' just like a geologist would have done, and let their findings to NASA stating emphatically that, as there is jarosite, on the Red Planet one day the water ran.    The jarosite is  a mineral difficult to identify, because it can be easily confused with limonite and goethite. It is a yellow-brown and more often being present in granular masses, powdery or earthy, sometimes forms small tabular crystals. One of its noticed properties is that it is water-insoluble. It is a potassium sulphate and iron hydrate, ie oxygen and hydrogen and has made it his "KFE3 ((SO4) 2 (OH) 6).    According to Dr. Jesús Martínez Frías, director of the Planetary Geology Laboratory of the Center for Astrobiology, mineralogy space "is now one of the most important fields of research, because the minerals are the best witnesses of the evolution of a planet."    The most important aspect of this discovery reminds Martínez-Frías, is that "scientists are going to have a clear informational landscape. We have already seen signs of gullies, and through space probes already knew that there could be water in the subsoil, by the detection of hydrogen and water ice at the South Pole. "    Martínez Frías ensures that these indications "suggest that there is water in the Martian subsurface in the form of 'permafrost', a mixture of water and ice which can be found in areas like Siberia. If so, to establish human colonies on the red planet would be much easier since they could draw water through drill and secure the humidification of the environment.    Some scientists also argue that the theory in the subsurface of Mars could have water right now in circulation, it would be possible by the volcanic activity that has the planet.    Despite the euphoria that reigned in the centers of NASA, scientific studies are yet to be developed. During the first six months, only investigators from the agency will have access to data, then the entire scientific community can work with them.    Currently, the agency has already covered the case. "NASA launched the mission specifically to determine whether at least part of the planet had a wet environment that could have harbored some kind of life," said James Garvin, chief scientist of the team of NASA. Mission accomplished. Everything come later, will be 'free'.
