All anorthosites found on Earth consist of coarse crystals, but some samples of the rock taken from the Moon are finely crystalline. Most anorthosites formed during Precambrian times. Anorthosite is not nearly as common here as it is on the Moon. Anorthosites on the Moon are extremely old, almost as old as the Moon itself. Anorthosites on Earth are pretty old too, mostly from the Proterozoic Eon. Anorthosite is a plutonic rock just as granite and gabbro and it is usually associated with the latter. Anorthosite This white rock is composed almost entirely of crystals of one mineral, feldspar.

Anorthosite is an intrusive igneous rock composed mainly of silicates called feldspar. It is an Earth rock that can be consi • Anorthosite was prominently represented in rock samples brought back from the Moon, and is important in investigations of Mars, Venus, and meteorites. 16. OCCURRENCE Anorthosite are occurred in different parts of the world. Some of them are listed below: 1. Sandford lake, New York.

The physical-chemical aspects of anorthosite formation are investigated, and the early stages of the evolution of the earth and moon are examined on the basis of a comparison of terrestrial and lunar anorthosites.

THE recent report from Houston1 proposed that the lunar highlands may be composed “predominantly” of anorthosite and gabbroic anorthosite. O'Hara has therefore suggested that some of the Pre On the Moon (1) there are no rocks rich in quartz or other silica polymorphs*, (2) in a given rock, particularly breccias, the average concentration of silica in the three main minerals, plagioclase, pyroxene, and olivine, are all about the same, and (3) in highlands rocks ilmenite is usually present only in small amounts (<3%), so silica concentrations of common lunar rocks vary by only a 2013-02-17 · to the Moon through impact events or during mantle overturn as suggested by previous studies7,11. 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.

These are magmatic rocks that have crystallized from the magma which is enriched in low- or high density minerals. 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.

[1] 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 Feldspathic Highland Terrain and the south and north polar regions.

However, there are numerous differences, nearly all associated with the lack of water and wind on the Moon. Typically, calcium-rich anorthosite deposits are small, irregular and contain too many impurities for commercial applications. The White Mountain ore body is geologically massive and homogeneous with no competitors.
