Mars Formed from Similar Building Blocks to That of Earth, Reveals Study of Martian Meteorites

 

Conel Alexander Wang Jianhua, including Carnegie and a team of scientists studied hydrogen from water Martian interior and found the building blocks of Mars from the ground up, but there were differences in the evolution of the two planets. This means that terrestrial planets, including Earth, are the sources of water - chondritic meteorites. However, unlike on Earth, Martian rock environment such as water contains volatiles, are not recyclable planet's deep interior.

December 1 to planet earth and their work in scientific papers will be published.

Most ethnic conflicts Mars, and water often surrounded by history. Martian southern hemisphere channels of water flowing sculpted speak loudly, but the area is pristine. As a result, planetary scientists often "warm and wet" as early as Mars and the Mars explained, "is cold and dry."

Debate in the scientific community focuses on how the planet's interior and crust and how they are different from the people of the earth. Martian water and other volatiles to investigate the history of NASA's Johnson Space Center in Houston, Carnegie, Lunar and Planetary Institute in Houston and a number of scientists and two water hydrogen isotopic crystals in Martian meteorites fall within compositions have been studied. meteorites, called shergottites were of the nature of Adam, but was rich in elements such as hydrogen, while others have been eliminated.

Used in the study of meteorites basaltic liquids are trapped, and ancient samples samples of different Martian atmosphere is unstable element. Martian meteorite from the planet's surface through a curtain to indicate little has changed. It's like a hydrogen isotopic composition of land. Martian meteorite is another layer that was in contact with the Martian atmosphere, this model shows that. Thus, meteorites water represent two very different sources. Samples of water and water from a deep interior of the planet Mars as it is based on, while the other represents the shallow crust and atmosphere samples.

He views the diverse compositions of Martian meteorites are competing for the account, "said Tomohiro Usui lead. They said no direct evidence from this study that the surface of Mars in Martian lavas Adam The content was. "

The two meteorites martian surface water hydrogen isotopic compositions of the Martian interior of the inferred geologic history has been different from water. Most likely, atmospheric water is lost preferentially space and light hydrogen isotope preferentially heavy hydrogen isotope (deuterium) is maintained.

Have included the enriched crustal meteor and atmospheric water can help solve the mystery. Martian meteorites components such as water, are enriched in an enrichment, from deep responsibility, or their interaction with Martian crust has been overprinted by?

"Enriched hydrogen isotopic composition of meteoric water clearly indicates that they have been overprinted, it's about the Martian meteorite scientists Martian mantle layer tells more about," Alexander said. . Instead, he said, other Martian meteorite find more information about the interior. '

of water in meteorites is also very different. Less than one means that the water concentration and the dry interior of Mars is. In contrast, 10 times more water enriched basalt from each other, suggesting that the surface of Mars at the same time can be very wet. So scientists now know that what we Martian meteorites Martian interior surface of the sample we tell you about are starting to talk about.

"Alexander" The geologic history of Mars to understand, about their environment both in need of more information,
