His conclusion is based on data from the experiment of the lunar radiometer soothsayer aboard NASA Lunar Reconnaissance Orbiter (LRO), not manned fully entera.La Moon spacecraft orbits associate some 31 miles from the surface of the moon.
New numbers previously invisible compositional differences in the Highlands crust of the moon to reveal and have confirmed the elements silicon and oxygen - material the existence of surprisingly rich in silica - substance containing in five regions of moles.
All minerals and therefore each rock absorbed and radiates energy with a unique spectral signature that can be measured, to his identity.For the first time in history reveal, dowser provides scientists with global, high-resolution maps infrared Moon, allow you to a final identification of silicates, often in the bark found.
Co-authors in the research include David Paige, principal investigator who drive soothsayer and Professor at the UCLA in Planetologie, Benjamin green Germany, a scientist at the laboratory of NASA received at UCLA in Paige; Timothy Glotch, an associate professor of Geosciences, the University of New York Stony Brook; and Paul Hayne, that his Ph.d. at UCLA this year see Paige to get.
Lunar geology can generally be divided into two categories: the Highlands, the anorthosite containing an igneous rock that rich that calcium, aluminium and Maria (Latin for "sea"), basalt, rich in iron and observations of the soothsayer magnesio.Las volcanic igneous rock are confirmed that more land moles accordance with compositions, but divided into two broad Categorías.Sin spectral signatures, you have also showed that the Highlands can be less homogeneous than I thought.
In a variety of fields, magician revealed the presence of Lunar soil compositions, rich in sodium anorthosite Típico.ESTOS soil crust reveals that there have been changes in the chemical industry and speed Ocean can cooling magma, which made the early Lunar crust, or "Processing" (point melt and solidify repeatedly) early lunar crust, said green, Germany.
Multi-site dowser has detected the presence of minerals that are found only in conjunction with rocks, extensive magmatic process - are exposed to, these are very silica, quartz, rich in potassium feldspar minerals and rich in sodium feldspar, the common mineral rock formed in the Earth's crust.
Siliceous minerals detection at these sites is one find meaningful because you in areas previously shown to display highly unusually high frequencies of thorium element, a proxy for occur lithologies, developed Paige said.
"" Silícicas features we've found on the moon are essential from the typical basaltic Mare and Highlands anorthosite, "said Glotch, lead author of one of the documents.""We see, these multiple configurations geological composition suggests that there have been several processes of production of these rocks can".
Steep slopes have some high silica, regions such as trafficking in human beings Gruithiusen and rough, surfaces - like dome in St. Helens, after the eruption formed said Glotch of lava domes can suggesting that they are created by the slow eruption viscous lava on the lunar surface.
In other regions, such as the crater Aristarchus siliceous spectral signatures are limited to craters and material ejected by his impacto.Esto that the excavation of the underground by these effects caused has suspended parts of PLUTONE, the institutions of the solidified magma u-Bahn from reaching the surface proposes.
As such materials make high silica in a glass that rich is ruled basaltic through the Highlands of calcium and iron and Maria magnesium-rich anorthosite?
High siliceous sites occur in Procellarum KREEP property (PKT), an expensive the mole area which was known for its wide basáltico.Esto volcanism scientists believe that material rich in silica present in this region a result of the hot of basaltic magma we interfere and recasting the Lunar crust.
However, regions, Belkovich Compton, way of PKT and its associated vulcanismo.La location of Compton Belkovich beats anomaly occurs before on the far side of the Moon, that the conditions, you have to sustainable production of heat and Volcanism on the PKT resulted in many smaller scales on the far side of the moon there been can.
Not obvious thing in data is lunar coat, pristine material evidence that previous studies suggested that you at some places on the surface material, rich in iron and magnesium lunar.Dicho exposed can be easy by Soothsayer, would be discovered Paige said.
In the pole South Aitken basin (SPA), largest crater, oldest and deepest deep enough the crust and mantle - have penetrated the moon - there is however no evidence for material of a cloak, said.
This time effects are unknown; perhaps no such risks coat material, or may occur in areas too small for soothsayer to recognize that Paige said.
However, it is likely the impact that these craters formed material coat, ditch since then crustal material inside and outside of the SPA have mixed with subsequent effects.
"" New data soothsayer help select of the appropriate samples for future missions of landing zurückzugebenden pages of SPA, "says Green Germany." """We want these examples use date effects, the formation of SPA and potentially lunar coat, exploring so it is important to use data soothsayer to identify areas with a minimum of mix".
Soothsayer still detailed maps of infrared reflection and moon for the rest of the mission solar Goddard Flight Center manages LRO.El LRO Greenbelt, MD NASA.
