Most of the images we see from Mars make its landscape look flat and wide, but in fact it's home to some of the largest mountains in the system whole supply. And while the planet was quite inactive, it was once very active. The Mars has winds and dunes that form prominent features on its face similar to what we see here on Earth, and a new study suggests that Mars could get much more common with & # 39 ; r Earth than we thought.
Meteorists are constantly falling through our sun, landing around the world. From time to time, small pieces of Mars survive the record through our environment and can be found – mainly in the Sahara and Antarctic desert – where researchers collect for study in the future. Newspaper released today Nature Communication says that these Martian meteorites could be formed from the same volcanic volcanic process in Hawaii.
The island's fuel mountains are created by what is known as "hot spot" or when the ground tile material comes to the surface and melts. A good example of this is a very active Kilauea volcano. But when these "hot spots" volcanoes are heavier and more heavier in creating and staining constant materials, they can create a different type volcano type. They become as heavy as a rock as they fold and grow physically the massive plate under at least Hawaii. As that bending happens, very similar to weld-saw, the area around the deeper volcanoes is flexible and creates the creation of new, potentially emerging bricks shot.
"If you're going to Oahu or some of these islands, you'll see this long-lasting volcano after the original volcanism. A good example of that is a diamond crater," he said. The geologist James Day, is a leader at the Scripps Oceanographic Institute at the University of California San Diego.
The Diamond Head crater on Oahu was formed due to tectonic stress from older volcanoes, more massive. "This equates exactly what we see in the martian meteorites," said Day.
Give the Mars: Scientists know about two types of Martian myths of the name shergottites and nakhlites, and while they sound on the same superhero team, they are very different in age and chemical composition. And although he has collected over 200 Martian meteorites, scientists have no idea of where they come on Mars. Although they know they are volcanic origin, if you've ever seen a geological map of Mars, you know that the planet has spread with volcanoes.
But the new research could give a big picture. Day and team analyzed the Martian team of 40 meteorites for their chemical composition and it was found that they shared some similarities to each other – not different from the way in which these volcanic rocks are on Earth associated. The nakhlites have a unique composition that does not fit the volcanoes that we will find on the ground, while the shergottites look like volcanoes such as Kilauea that form a hot spot. This is what Day thinks it could have happened on Mars. And Olympus Mons-the largest volcano in the solar system, which raises several times higher than Mt. Everest is sure in the task. The other Mars regions hold smaller, less well-known volcanoes like Diamondhead. A day suggests that, as we see around Hawaii, weights of large volcanoes such as Olympus Mons have bent and flexible a whole region of Mars up, creating smaller mountains, where nakhlites come.
"What's really about these two similar styles of lava or folcanoes is that both of them ask for a source that has already melted," says the Day . "What's happening in Diamondhead is that the plate is folded and squeezed and writes, and that little more that rich material can be pushed out – and that's it & What we see with Mars nahkalites ".
Kayla Lacovino, a post-doctoral researcher in experimental petroleum at the University of Arizona State, says what's cool about the study is her ability to explain all Martian, large and small volcanoes. "Their model seems to fit in with geochemical observations of Martian volcanic [from meteorite samples], and no other strange explanation is needed on how or why volcanoes form Mars. "
The day says that people have been searching for these meteorite sources for decades and now this can give them a place to search for the source. "If this model is correct, they should find this laptop away from the large volcanoes. They should find them in the region where the outer plate is in. be flexible. "
Dr. Paul Byrne, assistant environmental geology professor at the North Carolina State University, "We have long known that the massive volcanoes on Mars are older older versions of Hawaiian shield volcanoes. This study takes an interesting attitude by combining & # 39; what we know about the chemical composition of Martian meteorites with large-scale geophysical processes such as the flexibility of these large plates. "
Understanding the volcanic processes that once occur on Mars is not only important for the completion of the history of a Martian history, but it can help to decide on the ability to live as well. "If you do not have Earth vacancy, you do not have some of the necessary gases in the atmosphere to keep our biosphere alive," said Day. The nakhlites found on the Earth are rich in water, which requires water to help dissolve. This could suggest that the volcanoes on Mars are associated with the hydrological cycle.
"If we see this process happening on Earth, which could be like volcanism on other planets?" Is the answer, based on the Martian meteorites, yes, "says the Day. Now he and his colleagues have to wait for more satellite comments from these volcanic regions to see how well the data fits with hypothesis
"It's up to remote sensors now to go and look at their imaging and their spectacle data and decide if they match."
