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.

A video showing the anorthosite. Anorthosite is an intrusive igneous rock composed mainly of silicates called feldspar. It is an Earth rock that can be consi

In general, lunar feldspathic meteorites tend to be more anorthosite-rich, and poorer in KREEP, than their Apollo equivalents. 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.

Anorthosite moon

The isotopic measurements were made by taking samples of ferroan anorthosite (FAN), a type of moon crustal rock, which is considered to The Plat Sjambok Anorthosite and its tonalitic country rocks: Mesoproterozoic Moon. S Klemme, D Günther, K Hametner, S Prowatke, Thomas Zack Chemical (mineralogy) A plagioclase feldspar, the final member of the Albite-Anorthite solid solution series. Anorthite is very rare on Earth, but abundant in moon rocks. Our next broadcast will be from Fra Mauro on the surface of the moon.

Lunar anorthosite Anorthosite is a fascinating rock and sparks interest even among those who usually don’t care about rocks. The reason is simple. Anorthosite is often composed of mineral labradorite which is famous for an iridescent effect called labradorescence.

5 Nov 2016 The mean inclination of the Moon's orbit to the ecliptic plane (i.e. the apparent path of the Sun through the sky) is 5.145°. Because of this

[15] anorthosite under a 300x microscope So valued is this moon rock that there were detailed plans to create a veritable space port on the east coast of Harris and to blast it out in vast quantities. The moon rock would then be exported via huge vessels harnessing the rocks availability next to deep water.

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

Constraints on the 17 Feb 2013 grains in lunar anorthosites thought to sample the primary crust, obtained crystallization of the lunar magma ocean than a dry moon scenario A lunar structural model is proposed in which a 25-kilometer anorthosite crust, produced by magmatic fractionation, floats on denser gabbro.

While quartz is quite rare on the Moon, the abrasiveness of the quartz in GreenSpar may be useful in simulating the abrasiveness of the … Anorthosite is an almost monomineralic, feldspathic rock with a great variety of industrial applications (Table 1).

This white rock is composed almost entirely of crystals of one mineral, feldspar.

Specimen are two slices of this lunar meteorite, in presentation box, with certificaty (signed). NWA 10291 lunar meteorite was used in a study to compare the

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. The ancient crust of the Moon is believed to have been composed of the rock, anorthosite, a calcium-rich white rock. This ancient crust has been smashed and redistributed by countless meteoric impacts.
