Fig 2. The white rock is a piece of anorthosite, a rock type made up predominantly of the mineral anorthite (a plagioclase feldspar). The sample is known as “the Genesis Rock” as it is the first sample of crystalline pristine anorthosite returned, and helped to confirm the theory that the moon crystallized from a magma ocean.

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 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.

Geologists, hoping to learn more about the moon and its origins, selected the Hadley-Apennines landing site for precisely this reason. The global distribution of pure anorthosite on the Moon. Makiko Ohtake 1, Tsuneo Matsunaga 2, Junichi Haruyama 1, Yasuhiro Yokota 1, Tomokatsu Morota 1, Chikatoshi Honda 3, Yoshiko Ogawa 3, Anorthosite is not nearly as common here as it is on the Moon. Therefore we can conclude that despite being officially leucocratic it actually is usually associated with mafic rocks. These are magmatic rocks that have crystallized from the magma which is enriched in low- or high density minerals.

Bibliography. Ohtake et al. (2009) The global distribution of pure anorthosite on the Moon. When the Earth was first forming, anorthosite was probably produced the same way it was on the Moon. The Earth, however, is much bigger, and its crust was more dynamic.

The Apollo astronauts brought a very similar anorthosite back from the moon. This anorthosite was intruded into a previously 7 Oct 2019 (1970) Lunar anorthosites and a geophysical model of 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.

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].

The term anorthosite, from Frenc anorthose (term for plagioclase) was coined by Sterry Hunt. Discussion: Initial analyses suggests that the White Mountain anorthosite (aka GreenSpar) would be useful as a mechanical simulant for testing of systems and components bound for the Moon. While quartz is quite rare on the Moon, the abrasiveness of the quartz in GreenSpar may be useful in simulating the abrasiveness of the lunar regolith.

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.

The reason is simple. Anorthosite is often composed of mineral labradorite which is famous for an iridescent effect called labradorescence. Anorthosite .
