It was collected from the rim of Spur Crater and given the name 'Genesis Rock' by the astronauts of Apollo 15. They had been looking for evidence of the Moon's

That sample, nicknamed the Genesis Rock, sample number 15415, was an anorthosite, a piece of the moon’s primordial crust. Geologists, hoping to learn more about the moon and its origins, selected the Hadley-Apennines landing site for precisely this reason.

Geochimica et Cosmochimica Acta Supplements 1, 965-988. ). Here we show While Apollo astronauts returned with 382 kg of Moon rocks, not one milligram is primarily lunar anorthosite with approximately 90-95% plagioclase with minor 5 May 2020 The Apollo astronauts brought back samples of anorthosite from the Moon.

Highland Anorthosite When the moon first formed it probably had a surface composed mostly of feldspar-rich igneous rocks. This rock type still exists today and makes up the lunar highlands, which is the lighter-colored part of the moon visible from Earth.

• It consist of highly calcic plagioclase with It is middle Proterozoic in age. The Apollo astronauts brought a very similar anorthosite back from the moon.

Anorthosite rocks brought back to Earth by Apollo astronauts have helped researchers learn about the Moon’s geologic history. But the supply of anorthosite samples from the Moon is limited. Fortunately, the rock can also be found on Earth.

of New York, and on the moon. Ships in a Anorthite is the calcium-rich endmember of the plagioclase solid solution series, the other endmember being albite, NaAlSi 3 O 8.Anorthite also refers to plagioclase compositions with more than 90 molecular percent of the anorthite endmember. At 1 atmosphere, anorthite melts at 1553 °C.. Occurrence.

We present a new global survey of the purest anorthosite (PAN) rock using the Spectral Profiler onboard Kaguya. We found that PAN rocks are widely distributed over the Moon, including the Feldspath Anorthosite masses are relatively rare on Earth, and when they occur, they tend to be very old Precambrian rocks. As rare as anorthosite is on our planet, it is extremely abundant on the Moon, being the primary constituent of the lunar crust and the bright-colored lunar highlands.

These data are used to estimate the water content of the Moon’s interior at the time of the magma ocean, as well as that of the mare magma source regions. So far, ferroan anorthosite (FAN) is the only available lithology that is Anorthosites, rocks composed almost entirely of plagioclase feldspar, are the oldest rocks on the Moon. They appear to have formed when feldspar crystallized and floated to the top of a global magma ocean that surrounded the Moon soon after it formed. material (ORM) on the Moon, possibly from both the lower crust and the upper mantle [Yamamoto et al., 2010].

Introduction: A major unresolved question is whether there is an enrichment in plagioclase in the lunar crust. If a magma ocean once existed on the Moon, an anorthositic crust should have been formed by plagioclase floatation. Therefore, it is important to determine the distribution and modes of occurrence of anorthosite on the lunar surface. We have been conducting remote sensing studies of

Lunar meteorites represent samples of the Moon distinct from those collected by the Apollo or Luna missions. In general, lunar feldspathic meteorites tend to be more anorthosite-rich, and poorer in KREEP, than their Apollo equivalents. We present a new global survey of the purest anorthosite (PAN) rock using the Spectral Profiler onboard Kaguya.

Anorthosite. Found on both the moon and the Earth, anorthosite is an igneous rock primarily comprised of plagioclase feldspars. The name of the rock stems from the Greek an and orthos, which together mean “not upright,” a reference to the slanting form of the plagioclase crystals it contains.

The Moon highlands seem to be composed of anorthosite. We have both indirect and direct evidence for that. Measurements made recently by the Japanese lunar orbiter SELENE suggest that the lunar anorthosite may in many cases be almost totally monomineralic — composed entirely of plagioclase with very high calcium content. Anorthosite . This white rock is composed almost entirely of crystals of one mineral, feldspar. Rocks like this make up much of the Highlands of the Moon, where feldspar produces the light color.

It is an Earth rock that can be consi What is Anorthosite? Hudson’s anorthosite is a calcium feldspar rock which is primarily comprised of aluminum (31%), silicon (50%) and calcium (15%). The White Mountain anorthsoite is unique in its size and purity. Typically, calcium-rich anorthosite deposits are small, irregular and contain too many impurities for commercial applications.
